PSK2K – a new meteorscatter mode by DJ5HG

2012-01-21T16:28:00.002+03:00

PSK2k is high speed meteor scatter software written by Klaus DJ5HG (Prof. of Computer Science at University Hamburg). It allows 2 way MS QSO’s to be conducted with any suitable transceiver/PC/soundcard combination.

PSK2k is fully error correcting and call specific in operation so you will only see the QSO in progress and any non-QSO CQ or QST text. All other transmissions (other people also in QSO) are discarded. This allows multiple QSO’s to take place on a single frequency.

PSK2k can be operated in fully automatic mode if required. This enables QSO’s to be completed fully automatically without user intervention. Important advantages are that long term testing can be done, on QRP power for instance, without having to sit an monitor every period

INCREASING SOLAR ACTIVITY CLEANS UP SAT-DEBRIS:

2012-01-20T15:02:00.002+03:00

Earth's atmosphere has been puffing up in response to increasing levels of UV radiation from sunspots. This is good news for satellite operators, because a puffed up atmosphere helps clean up low-Earth orbit. "The number of cataloged debris in Earth orbit actually decreased during 2011," reports Nick Johnson in NASA's Orbital Debris Quarterly newsletter. "[The figure below] illustrates how the rate of debris reentries from the Fengyun-1C anti-satellite test of January 2007 increased during the past year."

ESA’s CubeSats ready for flight

2011-12-24T16:21:00.002+03:00

The first students' CubeSats to be sponsored by ESA’s Education Office have passed their Final Acceptance Review and have been declared ready for launch on board the maiden flight of Vega, the new ESA launcher. The launch window for this historic lift-off opens on 26 January and ends in the first week of February 2012.

The seven university-built picosatellites, each weighing only 1 kilogram, were integrated with the devices that will carry them during launch – the P-PODs, or Poly-Picosatellite Orbital Deployers – between late October and mid November. Before they could be cleared for launch, they had to pass a detailed technical examination known as the Final Acceptance Review.

TinySDR

2011-12-09T23:43:00.004+03:00

TinySDR by LY1GP It's a very simple direct conversion receiver consisting of nothing more than three parts:

1) Simple LC band pass filter;
2) Mixer; and
3) VFO.

No AF amplifier stage, it just feeds the output direct to the sound card MIC input and leaves it to do the amplification etc. Oh, and the VFO is coupled into the mixer via a phase transformer thereby providing two different phases - one at 0 degrees and one at 90 degrees - and thereby making the output that of (I believe) an IQ SDR receiver.
My 1st version work very nice ,It need more work at VFO.
tnx VK1IS for the webblog .

CubeSats

2011-12-09T21:47:00.000+03:00

Up to nine CubeSats built by European Universities will be flown during the debut of Europe's new Vega launch vehicle at the beginning of 2012. Together they represent a diverse range of designs and a variety of miniaturised technologies and sensors.

Up to nine CubeSats will be accommodated in three P-POD deployment systems which are to be mounted on the LARES primary payload. Each 1 kg CubeSat will be deployed into a high inclination, low Earth orbit, and is expected to operate in orbit for up to four years using a small ground station based at its respective university.

Nice comment Paul GM4ULS , Thank you OM .

Paul GM4ULS said...
Yesterday I was in a three-way QSO on 10m AM with two American operators. The technologies in use were very diverse. One of the stateside hams was an old Johnson Valiant transmitter, the other was using a Flex 5000A software defined set-up, and I was using a little single-band Chinese rig (Anytone AT5555). It's wonderful how such different technologies can be put to the same use.

Really it is joyful to listen to DX station with some discreet components and your PC.

The Crystal oscillator is not suitable for good band coverage.
Next step I will add a VFO. The one I've built for 20m was unstable suffering too much frequency drift!

European Student Moon Orbiter (ESMO)

2011-11-16T17:22:00.002+03:00

European Student Moon Orbiter (ESMO) is an education satellite project of the ESA's (European Space Agency) Education Office, and if successful it will be the first ever student-built spacecraft to leave Earth orbit and achieve an orbit around another solar system body

ESMO represents a unique and inspirational opportunity for university students, providing them with valuable and challenging hands-on space project experience in order to fully prepare a well qualified workforce for future ESA missions in the next decades. In addition, ESMO has a powerful education outreach aspect and strong attraction for students across Europe, by lowering the entry-level for lunar exploration to attainable university project activities. ESMO also represents an opportunity for students to contribute to the scientific knowledge and future European exploration of the Moon by returning new data and testing new technologies

Russian Mars Probe Stuck in Earth Orbit

2011-11-12T22:37:00.002+03:00

Russia’s Phobos-Grunt mission, which was designed to return samples of a Mars moon to Earth, remained stuck in Earth orbit as of Nov. 11.

The Russian space agency Roscosmos acknowledged in a Nov. 9 statement that Phobos-Grunt failed to ignite its on-board engines and became stuck in Earth orbit. Roscosmos added that it would attempt radio contact with the spacecraft late Nov. 9 Moscow time and try to “re-enable the main engines.” As of press time Nov. 11, Roscosmos had posted no further update. U.S. Strategic Command’s Space-Track website projected Nov. 10 that Phobos-Grunt would re-enter Earth’s atmosphere Nov. 26 if the spacecraft remained in its current orbit. More @ Space News

UKube-1 final design approved

2011-11-08T16:08:00.002+03:00

Posted on November 8, 2011 by M0TFO at uk.amsat.org

The UK space Agency and Astrium have just approved the final design of UKube-1 – the UK’s first CubeSat mission

On Thursday and Friday last week (3rd and 4th November 2011), a young team of engineers from Clyde Space presented their final design to a team of experts for the Critical Design Review (CDR) – the typical ‘gateway’ for space missions to proceed into the flight build and implementation phase.

The CDR for Ukube-1 thus marks an important point in the development of the mission, establishing the robustness of the design, the level of technical risk and the schedule/resourcing for the completion of all the tasks to build the flight spacecraft.

09:48 UTC Liftoff the Delta 2 with NPP – the world’s next-generation weather watcher heads to space
10:47 UTC NPP spacecraft has been released from the Delta 2 rocket’s second stage

11:26 UTC Confirmed deployment of P-POD-1 with AubieSat-1, Explorer-1 Prime and M-Cubed/COVE
11:28 UTC Confirmed deployment of P-POD-2 with RAX-2
11:30 UTC Confirmed deployment of P-POD-3. This P-POD contains the two-satellite DICE CubeSats (downlink at 465 MHz)

AubieSat 1 was made by Auburn University undergraduate students to study radio wave propagation through the ionosphere and test
protective films for solar panels.
Explorer 1 (Prime) Unit 2 from Montana State University also plans to probe space weather by monitoring trapped electrons in the horns of the radiation belts. It is named for America’s first satellite in space.
M-Cubed — the Michigan Multipurpose Minisat — comes from the University of Michigan to image the Earth and demonstrate the craft’s design for use by future projects.
The Radio Aurora Explorer 2, also from the University of Michigan, will study the microphysics that lead to plasma conditions that disrupt satellite communications.
The DICE (Dynamic Ionosphere CubeSat Experiment) will obtain electric field and electron density measurements for space weather research. The mission partners include Utah State, Clemson, Embry-Riddle Aeronautical University and the Atmospheric and Space Technology Research Associates.

PW-Sat to launch in January

2011-10-21T22:32:00.002+03:00

PW-Sat, a 1U CubeSat to be launched on the first VEGA flight in January, will carry a 145 to 435 MHz Amateur Radio transponder.

The single channel transponder will operate in a similar way to AO-16. The uplink on 145.900 MHz will be FM and the downlink on 435.020 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

PW-Sat should be launched into a 1450 by 300km 69.5 degree orbit and may be expected to have a lifetime of about 2 years before re-entry. It was built by students of Warsaw University of Technology in cooperation with the Space Research Centre and will be Poland’s first satellite.

PW-Sat has five modes of operation:
1. Receive only mode – no downlink
2. Beacon CW mode – Downlink On-Off Keying (OOK) CW (1kHz) 12 WPM on 435.020 MHz
3. Beacon BPSK mode – Downlink BPSK (3 kHz) 1200 bps AX25 (1 frame on 20 sec) on 435.020 MHz
4. Control communication mode. Downlink BPSK (3 kHz) 1200 bps AX25 on 435.020 MHz
5. Voice Repeater mode (aka “AO16″ mode) – Uplink145.900MHz FM (15 kHz) Downlink 435.020MHz DSB (3 kHz)

The first pair of satellites for Europe's Galileo global navigation satellite system has been lofted into orbit by the first Russian Soyuz vehicle ever launched from Europe's Spaceport in French Guiana in a milestone mission.

The Soyuz VS01 flight, operated by Arianespace, started with liftoff from the new launch complex in French Guiana at 10:30 GMT (12:30 CEST) on 21 October.
All of the Soyuz stages performed perfectly and the Fregat-MT upper stage released the Galileo satellites into their target orbit at 23 222 km altitude, 3 hours 49 minutes after liftoff.

What is Galileo?

Galileo is Europe’s own global navigation satellite system, providing a highly accurate, guaranteed global positioning service under civilian control. It is inter-operable with GPS and Glonass, the two other global satellite navigation systems.
By offering dual frequencies as standard, Galileo will deliver real-time positioning accuracy down to the metre range. It will guarantee availability of the service under all but the most extreme circumstances and will inform users within seconds of any satellite failure, making it suitable for safety-critical applications such as guiding cars, running trains and landing aircraft.

SRM University's satellite to take to the skies

Students of SRM University explaining the features of SRMSAT to be launched along with Megha-Tropiques satellite, on board PSLV-C18, to university president P. Sathyanarayanan and Chancellor T.R. Pachamuthu in Chennai on Monday. Photo: M. Vedhan

As the PSLV-C18 carrying Megha-Tropiques, an Indo-French venture to study the atmosphere in the tropical regions, blasts off from Satish Dhawan Space Centre at Sriharikota on October 12, students will be holding their breath at the ground station at SRM University in the city outskirts.

Along with Megha-Tropiques, SRMSAT, a nano-satellite, to monitor the green house gases, carbon-dioxide and water vapour in the tropics using a grating spectrometer will be launched.

“Fifty students were involved in design and development of SRMSAT, one of the first nano-satellites to be launched by a private university in the country,” said P. Sathyanarayanan, president, SRM University.

“There is a dedicated lab at the university. All the students involved in the project worked at the lab, after college hours, for the past two years, choosing to stay late in the night designing and testing each and every instrument,” says L.B. Vishal, a mechanical engineering student.

When they found that the power amplifier on board was dissipating heat, the students came up with heat sinks. Likewise, communication systems were arrived at after a lot of simulation. Students of 12 departments began work on the satellite with the survey of literature and Loganathan, a former ISRO scientist and product architect of space systems at the university, was available 24x7 to make the dream project a reality. ISRO scientists conducted a review of the project every month and gave insights.

Of cuboid model, the nano-satellite weighs 10.4 kg with three solar panels and was made at a cost of Rs.1.5 crore. The grating spectrometer will monitor earth-based sources and sinks of green house gases for the next two years.

Already in place, the ground station consists of two Yagi-Uda antennae with low noise amplifiers and Trans-receiver and auto tracking is through a satellite tracking programme. “The ground station has been tested by tracking the existing satellites,” says D. Narayana Rao, Director, Research.

“The University is in talks with ISRO to start a Centre for Space Sciences in its Chennai campus. It will take six months to crystallize,” Mr. Sathyanarayanan said. University Chancellor T.R. Pachamuthu and Vice-Chancellor M. Ponnavaikko were present.

More Cube Satellites toward sky nex 27 Oct 2011

E1P (Explorer 1 Prime)
Explorer 1 [PRIME] (E1P) is a Montana Space Grant Consortium Cubesat-class satellite in development by the Space Science and Engineering Laboratory (SSEL) at Montana State University.

RAX 2
RAX (Radio Aurora Explorer) is a student-built nanosatellite for ionospheric research. It is built on a triple CubeSat structure.

The RAX will measure the energy flow in the ionosphere, the highest part of Earth's atmosphere where solar radiation turns regular atoms into charged particles.

RAX is a Ground-to-Space Bistatic Radar Experiment. The RAX satellite will act as a receiver that will pick up signals from a ground radar transmitter. These radar pulses will reflect off disturbances, or space weather phenomena, in the ionosphere

AubieSat 1
AubieSat 1 is a 1U CubeSat built by students of the Auburn University. The science mission is to measure gamma rays produced by high-altitude thunderstorms. The data collected by the satellite will be transmitted to the ground station in the Physics Department for analysis.

M-Cubed
M-Cubed is a 1U CubeSat deceloped by the University of Michigan's Student Space Systems Fabrication Lab (S3FL). Development began in 2007.

The objective of MCubed is to obtain a mid resolution image to date of Earth with at least 60% land mass and a maximum of 20% cloud coverage from a single cubesat platform. S3FL is also developing the MCubed bus with the intention of making it a heritage design, thus allowing for future missions to be flown on the same bus

DICE
DICE (Dynamic Ionosphere CubeSat Experiment) will map geomagnetic Storm Enhanced Density (SED) plasma bulge and plume formations in Earth’s ionosphere. Two identical spinning spacecraft will measure plasma density and electric fields to determine the how and why of variations in ionospheric plasma density that affect the performance of communications, surveillance, and navigation systems on earth and in space.

ROSAT - 1 in 2000 chance of injury !!

2011-10-07T23:35:00.004+03:00

NASA calculates a 1-in-3200 chance of UARS causing injury or damage. But at the end of October or beginning of November, ROSAT – a 2.4-tonne X-ray telescope built by the German aerospace lab DLR and launched by NASA in 1990 – will re-enter the atmosphere, presenting a 1 in 2000 chance of injury.

The higher risk stems from the requirements of imaging X-rays in space, says DLR spokesperson Andreas Schütz. The spacecraft's mirrors had to be heavily shielded from heat that could have wrecked its X-ray sensing operations during its eight-year working life. But this means those mirrors will be far more likely to survive a fiery re-entry.

At the European Space Agency in Darmstadt, Germany, the head of the space debris office, Heiner Klinkrad, agrees that ROSAT's design means more of it will hit the surface. "This is indeed because ROSAT has a large mirror structure that survives high re-entry temperatures," he says

US Strategic Command tracks all space objects and the US-government-run Aerospace Corporation lists both upcoming and recent re-entries on its website. But ROSAT is not yet on the upcoming list because its re-entry time is far from certain.

The moment a craft will re-enter is difficult to predict because it is determined by two main factors.
First, the geometry of the tumbling satellite as it enters the upper atmosphere, which acts as a brake.
Second, the behaviour of the upper atmosphere itself, which grows and shrinks with the amount of solar activity, says Hugh Lewis, a space debris specialist at the University of Southampton, UK.

"Solar activity causes the atmosphere to expand upwards, causing more braking on space objects. The reason UARS is coming back sooner than expected is a sudden increase in solar activity. Indeed, we expect to see a higher rate of re-entries as we approach the solar maximum in 2013," he says.

The Ap index is a measure of the general level of geomagnetic activity over the globe for a given (UT) day. It is derived from measurements made at a number of stations world-wide of the variation of the geomagnetic field due to currents flowing in the earth's ionosphere and, to a lesser extent, in the earth's magnetosphere. The official values for Ap (and other related indices of geomagnetic activity such as the three-hour Kp index) are calculated by the GeoForschungsZentrum Potsdam Adolf-Schmidt-Observatory for Geomagnetism, D-14823 Niemegk (Germany),

A Radio Astronomy paper describes the use of the AMSAT-UK FUNcube Dongle Software Defined Radio as part of a Radio Telescope.

In the paper Dr David Morgan of the British Astronomical Association Radio Astronomy Group (BAA-RAG) describes how he used the FUNcube Dongle as the heart of a Radio Telescope operating on 1420 MHz.

He concludes that “A newly available SDR component has been shown to be very capable of acting as the heart of a simple and inexpensive three component radio telescope.”.

My prediction for ROSAT re-entry

2011-10-05T21:58:00.010+03:00

My prediction for ROSAT re-entry.
With in 20 days +-13 days !! :(

DLR information for ROSAT re-entry
The time and location of re-entry cannot be predicted precisely At present, scientists expect the X-ray satellite, which completes an orbit around Earth in about 90 minutes, to re-enter around the end of October 2011. Currently, this date can only be calculated to within plus/minus five weeks.This time slot of uncertainty will be reduced as the date of re-entry approaches. However, even one day before re-entry, the estimate will only be accurate to within plus/minus five hours .All areas under the orbit of ROSAT, which extends to 53 degrees northern and southern latitude could well be affected by its re-entry.

Happy 54th birthday to Sputnik I and the space race

2011-10-05T01:57:00.002+03:00

by Lauren Gold
Oct 04, 2011

The Soviet Union launched Sputnik I into Earth orbit 54 years ago today, winning the first lap of the space race to the shock of the United States.

“Without a doubt, Sputnik I was a huge milestone in the history of the space race. It marked the first time that humans successfully flew something higher than the boundaries of the earth’s atmosphere,” said Michael Smutko, distinguished senior lecturer of physics and astronomy at Northwestern University.

The 184-pound, shiny, spherical satellite could be seen with the naked eye, and ham radio operators picked up its beep. Suddenly, the Soviet Union had surpassed the U.S. in science. In the midst of the Cold War, the Soviets had the technology to place spacecraft in orbit over the U.S. It was an advantage no one had had until that point.

A fresh satellite for Russia's Glonass navigation network launched aboard a modernized Soyuz rocket Sunday (Oct. 2) on the first flight of the workhorse booster since a mishap doomed a mission in August.

The Soyuz 2-1b rocket lifted off at 2015 GMT (4:15 p.m. EDT) Sunday from the Plesetsk Cosmodrome in northern Russia. Launch occurred at 12:15 a.m. Moscow time.

The rocket's three core stages finished their work in less than 10 minutes, then a Fregat upper stage fired three times to reach a circular orbit almost 12,000 miles above Earth.

RAX-2 launch on 25 October 2011

2011-10-02T00:24:00.002+03:00

Dear Friends,

If you haven't heard, RAX-2 is launching this October 25th from Vandenberg Air Force Base in California. We are very excited about a second opportunity to fly the RAX mission. We have correctly the solar panel problem that led to the premature failure of RAX-1.

If you are interested in tracking RAX-2 please let me know. We would love the help.

Best regards,

Another Satellite's Re-entry (ROSAT)

2011-09-30T17:07:00.005+03:00

روسات هو قمر صناعي لقياس الأشعة السينية الآتية من بعض الأجرام السماوية. بلغ وزن القمر الصناعي بمعداته 2426 كيلوجرام وهو يعتبر أكبر قمرا صناعيا ألمانيا وزنا، وتكلف نحو 560 مليون مارك ألماني.

ROSAT re-entry

The defunct German Roentgen Satellite (ROSAT) is coming back to planet Earth -
sometime in late October or early November. The X-ray space observatory is less
than half the weight (2.4-tons) of the fallen UARS, but has an orbit that
ranges from latitudes of 53 degrees north and south, putting it in a position
where it can threaten a wide region that stretches from Canada to South
America. And while much of the spacecraft will disintegrate during it’s rapid
descent,.

ROSAT may not be larger, but this satellite will be one of the most dangerous satellites, giving Earth a 1 in 2000 chance of someone being hit. Anyone hit by this one would certainly not feel good and here is what makes this so dangerous.

ROSAT is Germany's Space Telescope. The satellite scope has mirrors that were designed and built for extreme heat. These mirrors will break, but most of it will be intact when it hits the Earth. The mirrors will act like a giant blade raining many pieces of glass onto a stretch of over 500 km.
UARS was dangerous due to the heavier pieces, but ROSAT will be dangerous because it will be like throwing knives out of an airplane and not knowing where thousands of these knives will land.

ROSAT simply is going to be one to watch over the next month. Recent solar storm activity is lessening the orbit day by day and the Sun will belch x-class flares toward the planet this week. This prompts the conclusion this satellite will come in next month, earlier than the later month forecast

China Space Station:Tiangong-1 Experimental Module Launched

2011-09-30T16:45:00.004+03:00

China launched an experimental module to lay the groundwork for a future space station on Thursday, underscoring its ambitions to become a major space power over the coming decade.

The box car-sized Tiangong-1 module was shot into space from the Jiuquan launch center on the edge of the Gobi Desert aboard a Long March 2FT1 rocket.

It is to move into an orbit 217 miles (350 kilometers) above the Earth and conduct surveys of Chinese farmland using special cameras, along with experiments involving growing crystals in zero gravity.

China then plans to launch an unmanned Shenzhou 8 spacecraft to practice remote-controlled docking maneuvers with the module, possibly within the next few weeks. Two more missions, at least one of them manned, are to meet up with it next year for further practice, with astronauts staying for up to one month.

The 8.5-ton module, whose name translates as "Heavenly Palace-1," is to stay aloft for two years, after which two other experimental modules are to be launched for additional tests before the actual station is launched in three sections between 2020and 2022.

Update #10
Fri, 23 Sep 2011 05:45:08 PM UTC+0300

As of 10:30 a.m. EDT on Sept. 23, 2011, the orbit of UARS was 100 miles by 105 miles (160 km by 170 km). Re-entry is expected late Friday, Sept. 23, or early Saturday, Sept. 24, Eastern Daylight Time. Solar activity is no longer the major factor in the satellite’s rate of descent. The satellite’s orientation or configuration apparently has changed, and that is now slowing its descent. There is a low probability any debris that survives re-entry will land in the United States, but the possibility cannot be discounted because of this changing rate of descent. It is still too early to predict the time and location of re-entry with any certainty, but predictions will become more refined in the next 12 to 18 hours.

Six ton UARS satellite to hit surface of the earth

2011-09-21T23:29:00.001+03:00

The major portion of the 5.7 metric tonne satellite is due for re-entry on the 23 or 24 September 2011 (UT). The majority of this satellite will burn up on re-entry, however there will be fall-out from this satellite. The track over which the debris will fall is around 800 kilometers (500 miles).

The inclination of this orbit is identical to the International Space Station - any region which can have a direct fly-over of the ISS has a chance of the re-entry taking place over it.

Predicting re-entry of any object is difficult, as an example; a recent solar flare caused the space station to rapidly loose 30km in altitude (over and above its normal decay rate).

Depending on the F10.7 levels (and therefore air density) and the orientation of the decaying satellite, the current best estimate is only a range at this stage - 23 September 2011 20:36 UT +/- 20 hours

Falling NASA UARS Satellite Observed While Still in Orbit

2011-09-21T23:10:00.001+03:00

The huge Upper Atmosphere Research Satellite (UARS) will be plummeting to Earth in an uncontrolled re-entry this week, but here’s an incredible video from astrophotographer extraordinaire Thierry Legault who shot footage of UARS with his 14-inch telescope. Legault was in Northern France (Dunkerque) last week to attempt to capture views of the satellite, and had success on September 15, 2011 between 04:42:14 and 04:44:02 UTC, just 8-9 days before its atmospheric reentry, when it was at an altitude of only 250 km. The tumbling, uncontrolled nature of the satellite is obvious in this video, and various components are visible, such as the body itself and the solar arrays.

NASA has selected 20 small satellites to fly as auxiliary cargo aboard rockets planned to launch in 2011 and 2012. The proposed CubeSats come from a high school in Virginia, universities across the country, NASA field centers and Department of Defense organizations. CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh 2.2 pounds or less.

The selections are from the second round of the CubeSat Launch Initiative. The satellites are expected to conduct technology demonstrations, educational research or science missions. The selected spacecraft are eligible for flight after final negotiations when an opportunity arises. The satellites come from the following organizations, which include the first high school proposal selected for a CubeSat flight:

-- Air Force Research Lab, Wright-Patterson Air Force Base, Ohio

Space travel powered by helium balloon

2011-08-23T02:26:00.001+03:00

“Bloon” is a six-person pod designed by Spanish company zero2infinity that will rise to the edge of the atmosphere, powered by a helium balloon. The cabin holds four passengers and two pilots for the three-hour flight, 36km above the earth’s surface. The flights will launch at night, so passengers can watch the sun rise over the curvature of the earth. While admiring the world from near space, in-flight information about the altitude and range of view will be displayed directly on the pod’s windows. To return to earth, the helium is vented slowly, then the balloon or sail separates from the pod, deploying a parafoil. The pod pops its airbags and is guided in for a landing. Bloon uses zero propellants, so there are no emissions or noise pollution.

The full ticket price is 110,000 euros, and for a deposit of 8,000 euros, customers can request when and from where they want to fly. Flights will lift off sometime between 2013 and 2015. A “minibloon” manned test flight is set for 2012.
