Hello all,

We are glad to inform you that Pratham, IITB's Student Satellite is
expected to launch with the help of PSLV-C35 on 26th September, 2016 at
9:12 AM.
The following are the TLE data for the satellite:

16005A      16270.25119097     0.00000311       00000-0     59418-4     0
98.2057    329.0542    0028038    267.7677   9.1998   14.63716875    11

Any update in these will be notified at the earliest. We would love you all
to be a part of the project and help us in tracking our satellite.
There are basically
two downlink for the satellite, 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 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: 145.98 MHz
Modulation: CW
Words per minute: 30
Power Emitted: 0.2 W (23 dBm)

To be switched on only over India and France
Modulation: FSK
Rate: 1200 bps
Power Emitted: 0.06 W (18 dBm)
