The satellite Pratham built by students at the Indian Institute of Technology Bombay is expected to launch on the Indian PSLV-C35 mission planned for 0342 UT on Monday, September 26, 2016.
Update Sept 29: Reports on AMSAT-BB indicate the Pratham CW beacon on 145.980 MHz is active
Pratham, a 300x300x300mm satellite with a mass of 10 kg, aims to measure total electron count in a 800 km altitude Sun Synchronous Orbit (SSO).
Aayush Yadav of the Pratham team writes:
We, students of IIT Bombay, are glad to inform you that our project, Pratham, is ready and expected to launch with PSLV-C35. We would be really happy if you all joined us in receiving our satellite’s beacon, details given below:
The beacon is estimated to switch on in the window of 25-30 degrees North and 4-8 degrees East as per the current TLE’s. Once switched on, it will remain so through out it’s orbit. The telemetry data will be switched on only over Europe (France) and India because of our power constraints. If you could, please receive the beacon and/or telemetry of the satellite and report back to the mail id’s as given below. The information for the satellite transmissions is given below,
Frequency: 145.980 MHz
Words per minute: 30
Power Emitted: 0.2 W (23 dBm)
Telemetry: To be switched on only over India and Europe (France)
Frequency: 437.455 MHz
Rate: 1200 bps
Power Emitted: 0.06 W (18 dBm)
