The WREN team report that they have had no confirmed reception of the signal from their SSTV PocketQube satellite which was launched on November 21.

These are the TLEs the team are currently using for WREN:

WREN2
1 10000U 00000 13325.30958333 .00066391 00000-0 78737-2 0 00001
2 10000 097.8055 037.9628 0031909 207.6761 327.4099 14.84238859000010

WREN is transmitting nominally on 437.405 MHz (+/- 10 kHz Doppler shift). The length of the beacon is 1.6 seconds. The beacon is AFSK-modulated. At the following link you can download the Telemetry Decoder and an Audio File of the beacon in order to get an idea how it sounds:

The team say:

“We need help from every Amateur radio operator and Ground station operator we can get”

On Monday, November 25, both the BBC Breakfast show and BBC News broadcast a report on the amateur radio FUNcube-1 satellite.

The report was filmed in the RSGB National Radio Centre (NRC) at Bletchley Park and at Abbeys Primary School in Bletchley.

UniSat-5 Mission Update November 24

UniSat-5 with labelsThe Group of Astrodynamics for the Use of Space Systems (GAUSS) issued this update on November 24 at 22:33 UT.

Dear all,

After the successful DNEPR cluster launch we will like to give you a brief update about the UniSat-5 mission and the released satellites:

• Eagle-1 and Eagle-2 have been received and are working perfectly
• HUMSAT-D already finished the commissioning of the platform, but none of the current TLE’s fit to Doppler shift measurements. Information about Doppler shift is very welcome!
• WREN was heard today [Nov 24]. The TLE used are:

1 39422U 13066G 13326.48861818 -.00000055 00000-0 00000+0 0 75
2 39422 097.8066 039.1177 0023760 211.9046 148.0730 14.86334042 151

The beacon is 1.6 seconds. Wren is sending nominally on 437.405 MHz. The beacon is AFSK-modulated.
For more information contact Paul Kocyla from Stadoku at Paul.Kocyla<at>rwth-aachen.de

• I-Cube [CW] beacon has been received from UK and from Pakistan. They are currently working on commanding the satellite
• UniSat-5 doesn’t have a beacon and the ground station from Roma, Vigo, MSU and California are working on commanding it
• PUCPSAT team needs your help: Beacon every 20 sec. at 145.840 MHz, AX.25 at 1200 bps

Information about object identification in the TLE are very welcome.

Thank you,

The CubeSat team at the University of Khartoum ST2UOK have been tracking and capturing telemetry data from FUNcube-1 (AO-73) since it was launched on November 21.

KN-SAT-1 Picture 1The team are developing their own CubeSat KN-SAT and recently completed the design and development of the Prototype-2.

Triton-1 Update November 24

Triton-1 in orbit

Triton-1 in orbit

Triton-1 is a 3U CubeSat from ISIS-BV (Innovative Solutions In Space BV) that carries a 435/145 FM to DSB transponder which is expected to be available for amateur radio use 3 months after launch.

This update was issued at 22:23 on November 24, 2013.

Hi all,

We have put an AX.25 mode beacon content decoding document on the Triton-1 amateur radio information page. This document contains the conversions from raw nominal mode beacon telemetry to engineering values.

See http://www.isispace.nl/HAM/

Best regards on behalf of the team,

Wouter Jan Ubbels PE4WJ

Jason Charles N4JTC has posted an inexpensive way to listen and decode the FUNcube-1 (AO-73) telemetry beacon on 145.935 MHz using the cheap RTL-SDR dongle.

See the post on Jason’s website at http://www.n4jtc.com/?p=579

Download the Dashboard App to receive the telemetry and upload it to the Data Warehouse.
