CubeSats satellite operations update

On 13 February, the new Vega rocket delivered seven ESA-sponsored CubeSats into low Earth orbit. Since then, ESA’s Education Office has maintained frequent contacts with the student teams to follow the progress of their satellite operations.

For each team, this is the first hands-on experience of operating an orbiting satellite, and some of them have had to deal with some challenging difficulties

Masat-1 EPS &TCS Telemetry

Orbit # 567

Masat-1 is going to shape the concept & the mission of CubeSat

IMHO Masat-1 success is going to shape the concept and the mission of CubeSat in the future.

The success reflects the big effort of the Masat-1 team to produce this CubeSat with perfect performance since the first day of the launch.

Here are some features of this success :

1- The good telemetry signal.
2- Nice decoder software.
3- Continuous update to the decoder software and release many new versions.
4- Very helpful web page.
5- Then the Masat-1 made history again when it captured the first satellite space photographs on 8 March 2012.



Masat-1 web page

New software TNC works great with Satellite !

Its interest to test new TNC software direct on a satellite.
The software is Soundmodem by UZ7HO .It uses the AGW Packet Engine API and emulates the AGW Packet Engine TCP interface. I have a long history with the wounderful AGW packet engine software . But I found the Soundmodem have a nice and friendly UGI .More easy to setup and less prone to crush. The Soundmodem works great with UISS too.
I copied Fastrac Oscar 70 Beacon using soundmodem alone @ 20:48 UTC

Masat-1 is Object E

I tried the last Masat-1 decoder (version: 2012. 03. 13.) on the last pass
22:11 22:19 UTC.
It works so fine ,A total of 92 packets captured from Object E not from MO-72
as states on the last 2L Keppler element !!

Masat-1 captured the first Hungarian satellite photographs from space

Masat-1, the First Hungarian Satellite made history again when it captured the first satellite space photographs on 8 March 2012 This first photo shows the southern section of the African continent. The next photos were made of Australia and Antarctica, in a quality and quantity unprecedented in the CubeSat realm.

VO-52 Turned On

Dear VO-52 users,
The commands to 'Turn On' the transponder # 2 (Dutch transponder, made
by Williams PE1RAH) on-board VO-52 was successfully sent during
14:00 UT 35 deg ascending Node pass over Bangalore, India.

The sent commands were successfully received, acknowledged and
confirmed by the telemetry. Subsequently, the transponder # 2 is now
'ON' and Williams CW message beacon was heard again after a gap of
approximately 6 years & 4 months.

The beacon signal was heard loud and strong here at Bangalore.



A detailed Initial reports addressed to:
tprangan@istrac.org
and a copy to
wmy@isac.gov.in
would be greatly appreciated.

Winds at the edge of space

Five sounding rockets will launch from NASA's Wallops Flight Facility in Virginia releasing a chemical tracer into the air. The chemical – a substance called trimethyl aluminum (TMA) -- forms milky, white clouds that allow those on the ground to "see" the winds in space and track them with cameras. In addition, two of the rockets will have instrumented payloads to measure pressure and temperature in the atmosphere.
The launch will take place on a clear night between March 14 and April 3.
The rockets will be launched on a clear night within a period of minutes, so the trails can all be seen at the same time. The trimethyl aluminum will then be released in space out over the Atlantic Ocean at altitudes from 50 to 90 miles. The cloud tracers will last for up to 20 minutes and will be visible in the mid-Atlantic region, and along the east coast of the United States from parts of South Carolina to New Jersey.

HAMSAT VO-52 Status

Subject: [amsat-bb] HAMSAT VO-52 Status
Date: Tue, 06 Mar 2012 13:22:48 +0530

Hello All,
Looking at the discussions and the concerns expressed about VO-52,all
that I can share at this moment is 'HAMSAT VO-52' is in 'Excellent
Health' after recovery operations. Right now, it is under observation.
However, decision about switching 'ON' the transponder is pending
clearance. Decision expected in other couple of days.
The user community will be informed well in advance about the
transponder switching.

with regards,

Mani, VU2WMY

Columbus patch antennas position!!

During the last few days while I was trying UHF Packet on the international space station .I noticed several time a sudden dip in the signal strength and loss in connection with packet system. ISS elevation was reasonable and the signal strength on the VHF packet system was strong!
I’m thinking of 3 cases:
1- The patch antennas position!
(The patch antennas are fixed on the Meteorite Debris Panels (MDP) protecting the hull of Columbus. On the port cone of the module, where it attaches to the ISS )
http://www.ariss-eu.org/columbus.htm
2- Radio and power used!
3- Doppler Effect!
As long as the signal dip was sharp and suddenly
And the transceiver was drive by Doppler shift correction software
I think the position of patch antennas plays the major role for the sudden signal strength weakness.
More Information needed to confirm this notice.
