STRaND-1 Telemetry 12-11-2013

STRaND-1 Telemetry 12-11-2013 20:29 UTC

This evening I found it difficult to decode the data that was send by the STRaND-1 satellite. Where not to long ago the amount of frames received where normally more then 500, this even only a hand full. Signal where at times strong enough but the receive combination that I use wasn’t working this evening, or something is changed at the side of the satellite.

Here is something that I could decode:

AO-27 recovery operations are underway

Amrad Oscar AO-27 PreFlightLet’s keep our fingers crossed

As of Oct 5, 2012 AO-27 is off-line and the groundstation team is working on a possible solution as one can read on the AO-27 website. After a long periode of silence I was pointed out by N8HM that there was news on the AO-27 website.

Oct 29th, 2013
Recovery operations are underway again for AO-27.
We will try to keep the website up to date with any infomation.

ISS Slow Scan Active

ISS MAI-75 Slow Scan experiment

ISS-MAI-75 29-10-2013 11:45UTCDmitry Pashkov UB4UAD reported that the Slow Scan Television (SSTV) experiment MAI-75 is active during October 28-29, 2013.

He also reports that on October 31, 2013 SSTV images will be transmitted from the ISS on 145.800 MHz showing photographic images of the life and work of the first cosmonaut Yuri Gagarin.

Today at the ISS pass from 12:45 UTC I received the following SSTV image from the International Space Station. The transmissions start late in the pass when ISS is flying over Russia. Therefor I could only receive one image with perfect quality.

Everything you want to now about ISS and amateur radio can be found at the website ISS Fanclub. They are also active on twitter so you don’t have to miss anything.

CUSat Cornell UniversityNothing heard from CUSat

Since Wednesday, October 16 there is nothing heard from the Scientific satellite CUSat. Maybe you can listen for it on 437.405 FM. Normally the satellite is transmitting in 1 minute interval with 1k2 AFSK.

XATCOBEO Telemetry 19-10-2013 18:01 UTC

Xatcobeo transmits in 437.365 MHz , this frequency was coordinated with IARU to avoid interferences with other satellites in the Amateur Satellite Service. The modulation used by the TTC subsystem is FM with FFSK/MSK at 1200bps in the baseband. One cycle of 1200Hz represents a logic ‘1’, one-and-a-half cycles of 1800Hz represents a logic ‘0’. Output RF power is 27 dBm. A Turnstile antenna is used on-board.

Xatcobeo ModelCW beacon: Xatcobeo transmits a CW beacon every 75/150 seconds and may transmit housekeeping (HK) frames (see next section) intercalated between beacons if TM is activated. CW is transmitted at 20 WPM as an 800Hz audio on-off keyed signal in FM. CW beacon can contain different parameters: battery voltage (V), signal received (dBm), temperatures (c, Celsius degrees).
