Hello! My name is Tolkynay (Tori) for short. I am from Kazakhstan, our nanosatellite “al-Farabi-2” is going to be launched today with Falcon 9. Thank you to Libre Space Foundation about sharing information. We would like to ask radio amateurs from all over the world to catch the signal from our al-Farabi-2! Below we wil be giving some information. I am not fully recognized with what kind of information should be provided here, but always in the line if some clarifications are needed.
The satellite was developed and assembled by al-Farabi Kazakh National University students with the purpose to conduct scientific experiments in space.
The satellite will transmit the CW signals with the “AF-2” message every 3 minutes.
Satellite data:
Callsign: UN1GWA
Frequency: 436,5 MHz
Modulation: CW.
Output power: 1 W.
Antenna: non-directional
Telemetry frequency: 436,5 MHz
Telemetry modulation: GMSK-4800
Initial orbital data:
UTC time at liftoff: 323:18:31:47.990
UTC time of current state: 323:19:14:59.490
Mission elapsed time (s): +2591.50
ECEF (X,Y,Z) Position (m): +299136.050, +1606142.483, -6757861.349
ECEF (X,Y,Z) Velocity* (m/s): +5500.939, +5093.215, +1454.386
LVLH to BODY quaternion (S,X,Y,Z): +0.0064870, -0.9999740, -0.0007769, -0.0030674
Inertial body rates (X,Y,Z) (deg/s): +0.1688750, +0.0721098, -0.0220705
Apogee Altitude** (km): +574.414
Perigee Altitude** (km): +558.083
Inclination (deg): +97.775

Longitude of the Asc. Node*** (deg): +45.066
True Anomaly (deg): +182.386
- ECEF velocity is Earth relative
** Apogee/Perigee altitude assumes a spherical Earth, 6378.137 km radius
*** LAN is defined as the angle between Greenwich Meridian (Earth longitude 0)
and the ascending node
**** All orbital elements are defined as osculating at the instant of the printed state. Orbital elements are computed in an inertial frame realized by inertially freezing the WGS84 ECEF frame at time of current state.
And of course, we have some gifts for that:
First 10 radioamateurs which will receive the satellite signals and will send the confirmation of their reception at the email address stated below will receive memorial plaque. Email: ntpkaznu@gmail.com
Email subject must contain the following text: al-farabi-2. It’s advised that email should only contain the link to the video made and posted on the YouTube or similar video hosting.
Email must contain the name and surname of the radio amateur, his/her callsign (if available), reception time/date, QTH-locator of the station used to receive the signals as well as brief information about the receiver and antenna used. All radio amateurs who will send their signal reception confirmation will receive memorial diplomas issued in the electronic format.
