Decoding telemetry data from satellites 🚀

Here, to date, are the screen shots of the decoded telemetry data that I've been able to receive from a small range of satellites.

• CAS-9/XW-3/HO-113 was launched from the Taiyuan Satellite Launch Centre in China.

It carries a CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder for SSB and CW, a visible light band space camera and an experimental thermoelectric generator for high school students.

It took several attempts to obtain a strong enough signal for decodable data; an 84 degree pass finally produced the necessary results. 😊

The decoded data I received was as follows:

There may be an issue with with SWR - note the forward and reflected power levels which give a calculated figure of about 5.5:1.

• The Bobcat-1 satellite was developed at the Ohio University Avionics Engineering Centre and launched on October 2nd 2020 and deployed into orbit from the ISS on November 5, 2020.

It is a 3U cubesat deployed to study Global Navigation Satellite Systems (GNSS). As implied, the global network includes Europe’s Galileo, the USA’s NAVSTAR GPS system, Russia’s GLONASS and China’s BeiDou Navigation Satellite System. Studies will hopefully improve the availability and performance of these navigation systems for other satellites and spacecraft.

It will probably de-orbit sometime early in 2022.

 

• The KSU-Cubesat (King Saud University Cubesat) is a 1U cubesat which was developed by students and researchers of the College of Engineering at King Saud University, Saudi Arabia.
  
  It was launched on March 22nd 2021 from Kazakhstan and takes photographs of the Earth, moon and space and sends the images to the College ground station.

• JAISAT-1 (Joint Academy for Intelligent Satellites for Amateur Radio of Thailand) - a 3U cubesat - was launched on July 5th 2019.  It is Thailand's first amateur radio satellite.
  
  The JAISAT-1 Beacon signal is on 435.700 MHz in GMSK Mobitex 4800 bps and it carries an amateur radio 2m to 70 cm linear transponder for SSB and CW communications.
