TurkSat3U status

Beacon Status:
Nothing copied since last Friday 26 April.!!

A weak continuous signal (carrier?) with slight Doppler was noticed during the last pass 19:28 19:40 UTC This signal came around the TCA and disappeared around the LOS. Not exactly at the down-link frequency but around  +/- 437.200 MHz.
Yes many sky junks around ! , which can be the cause of such a QRM, It may be interesting to monitor this frequency as long as the signal disappeared with the TurkSat3U's LOS.

Another event occurred last Friday, April 26, 2013, 10:39 AM, while I was monitoring Turksat3U I've noticed two CW signals overlap each other!!, The 1st signal was a clear TurkSat3U Beacon; the other signal was an ambiguous CW signal !.You can see the audio analysis at the previous post ..
Mike(DK3WN)  identified the source of the other signal as a failed CW beacon of RS-40.
(Thanks Mike for help)

Transponder status:
Loop test performed several time ,but nothing heard or seen on the waterfall.

At my previous post Mr.Ahmet Sofyalı from  Space Systems Design and Testing Laboratuary of ITU. Had posted a comment stated:
Since Friday (April 26th), TURKSAT 3USAT could not be heard again.
Thanks Mr.Sofyalı for visiting and comment .
Unfortunately this record from Friday, April 26, 2013, 10:39:51 AM
Still we are QRV with great hope.

See previous post  Phonesat Images received

Turksat 3Usat cw beacon heard over Africa

A weak turksat beacon heard - low pass elevation 
Xponder not heard - !!!
Cubebug-1 beacon not heard !!!

Congratulation to all team for successful launch and orbiting  

At the 1st pass I  detect the beacon too at the  I&Q audio  record file ! 
RTL-SDR confused me with it low resolution  . again congratulation

Below is the recent email from PhoneSat team gave more info, plus the new 2TL.
We have finally received official TLEs of the three satellites. They have been updated to the website. We also add them in this email:

I seems that Alexander and Bell are flying very close to each other and Graham is a bit more distant. As for now, the TLEs that we had seem to point more towards Graham, but we would suggest targeting Alexander and Bell.
We are working on releasing the reconstructed pictures that we have so far, we still need your help to finalize the picture.
Again, thank you very much for your great collaboration, we will let you know once the pictures are on the site.
Thanks,
PhoneSat team

Orbital Sciences Corporation has confirmed the next probable attempt to test launch its Antares rocket from NASA's Wallops Flight Facility on Wallops Island, Va., will be no earlier than Friday, April 19, at 5 p.m. EDT.

Nanosatellite linear transponder (4) Delfi-n3Xt

Delfi-n3Xt (Delfi Triple CubeSat NeXt) is another Nanosatellite from Delft University of Technology (TU Delft) with liner transponder. Launch is scheduled for Jul 2013.

Compared to Delfi-C3, Delfi-n3Xt will be equipped with batteries, an active ADCS, and a high-speed S-band transmitter.

The Communication Subsystem will carry no less than three radios:

The PTRX (Primary Transceiver)
provides an UHF (435 MHz) up-link at 600 or 1200 bit/s. The down-link is in VHF (145 MHz) at 1.2 or 2.4 Kbit/s. The PTRX is of Delfi-C3 heritage. The PTRX is further complimented with a linear transponder (UHF up, VHF down) . And might also be equipped with an experimental OLFAR (Orbiting Low Frequency ARray) transponder for very low frequencies.

The payload ITRX (ISIS Transceiver)
The frequency bands used by the ITRX are VHF for down-link and UHF for up-link. The data rates are 1200 bit/s for up-link and a maximum of 9600 bit/s for the down-link, which can be variable. The maximum transmitter power will be at least 400 mW,
Besides flying as a payload, the up-link receiver of the ITRX can be used as a backup command receiver for commanding the satellite. Furthermore, the transceiver will be used for ranging purposes, whereby the transceiver acts as a transponder.

The high-speed STX (S-band Transmitter).
The STX (S-band Transmitter) of 2.4 GHz provides variable down-link data rates between 9.6 and 250 Kbit/s.

In addition, there is the antenna subsystem consisting of at least 9 antennas. Four UHF up-link antennas are positioned alongside the solar panels, and four VHF down-link antennas are mounted canted turnstile at the far end of the satellite. The high-speed S-band down-link will use one or multiple patch antennas.

Estonia’s ESTCube-1 integrated into Vega

The multi-satellite payload “stack” for Vega’s upcoming flight from French Guiana is now taking shape as the Arianespace-managed integration process advances at the Spaceport. This activity began in the Spaceport’sS5 clean room facility with installation of Estonia’s ESTCube-1 student nanosatellite on a flat mounting surface called the P2 Plate, which serves as the lower interface in the Vega’s payload stack. The small cube-shaped satellite and its dispenser were integrated using a bracket that was mounted to the P2 Plate.

The next step was the placement of Vietnam’s VNREDSat-1 with its interface adapter on the P2 Plate, joining ESTCube-1.

Both satellites are located in the payload stack’s lower position, and will ride inside a larger dispenser system called VESPA. Completing the payload arrangement will be installation of the mission’s third satellite—Proba-V—which is to ride atop the VESPA dispenser. Proba-V will have a mass at liftoff of 160kg. and is to monitor global vegetation growth. Produced by prime contractor QinetiQ Space Belgium for the European Space Agency, the satellite is equipped with a newer version of the Vegetation imaging instrument that previously operated on the Spot series of Earth observation satellites—which also were orbited by Arianespace.

The 1.3kg. ESTCube-1 cubesat was designed to test electric solar wind sail technologies, as well as help establish an Estonian infrastructure for future space projects. It was built by a collaboration of students from Tartu University, Estonian Aviation Academy, Tallinn University of Technology and University of Life Sciences —and was developed in conjunction with the Finnish Meteorological Institute and the German Space Center (DLR).

Nanosatellite linear transponder (3) TurkSat

TurkSat is a 3U CubeSat, the first communication nanosatellite mission of ITU (Istanbul Technical University),

The VHF/UHF transponder is the main payload to provide two -way radio communications. The VHF uplink has a frequency of 145.990 MHz, the UHF downlink band has a frequency of 435.200 – 435.250 MHz. The transponder consists of amplifiers, filters, mixers and AGC (Automatic Gain Control) stages. The VHF uplink signal is up-converted to the UHF downlink signal linearly. The system has again of 150 dB with 60 dB of the total gain being adjustable. The communication system with transponder has a link margin of 10 dB.

Uplink center frequency	145.965 MHz
Downlink center frequency	435.225 MHz
Bandwidth	±25 kHz
Output power	30 dBm (1W)
Receive sensitivity, gain	-120 dBm, 150 dB
Total power consumption	< 3 W
Automatic gain control	Yes
Antennas	Monopole (Cu-Be)
PCB (Printed Circuit Board) size	8.8 cm x 8.8 cm x 0.5 cm
Transponder mass	< 250 g
Supply voltage	2.8 V, 3.3 V, 5 V DC
Microcontroller	MSP430F5438

Nanosatellite linear transponder (2)

I’ve been tracking and monitoring the STRaND-1 satellite during last few weeks before it became silent at March 31.
I was so impressed from its down-link signal strength and quality. I have no idea how much power it was pumping? I guessed around 500mw or more!

Considering my average ground station setup as a reference, I should say that the 3unit cubesat provides more than enough power to drive high  speed data link .

could be there  enough power to drive  a Liner transponder?!
what will be the overall efficiency of the transponder on board 3U cubesat?
And what methods taken during the design to eliminate the power-hog ?
A Multi AGC channels or LEILA ?

I hope more modern technique been used to handle and equally bending the Nano-satellite transponder power. It is still QRP transponder ! comparing to a Micosat transponder.

*TURKSAT-3USAT is a new Nano-satellite with linear transponder planned to launch on April 26, 2013  into a 680 km Low Earth Orbit .
