At ISS altitude it will take care of itself after a few months so don't worry about space junk.

Dear everyone,

According to latest news from JAXA, deployment of the 5 CubeSats to space by the robotic arm of Kibo module on the ISS will be carried out on Thursday, September  27. Here is the plan:

-          First, 15h10 to 15h20: WE WISH and RAIKO from POD #1

-          Second,16h30 to 16h40: TechEdSat, F-1 và FITSAT-1 from POD#2


All time in UTC. The event is planned to be broadcasted live on the following websites:




30 minutes after deployment from the station, F-1 will begin transmitting beacon alternatively on its main and backup channels. Telemetry and beacon data from F-1 contain critical information about the satellite’s health (battery & solar cell voltages, temperature readings) and they are very important to us, especially in the first week of operation. Thus, we would like to ask the amateur radio community to help in tracking and receiving data from F-1 CubeSat.


Here’s a quick summary of F-1’ frequencies:

-          145.980 MHz: main channel, 1.0W RF output, FM, AFSK 1200bps, one
telemetry packet every 30 seconds, operates in the dark by default (but can be commanded later to operate in sunlight as well)

-          437.485 MHz: backup channel, 0.2W RF output, FM, PWM CW beacon,
each beacon transmission lasts about 20 seconds then 60 seconds delay, only operates in sunlight


More information and guide to download F-1 telemetry decoder can be found at http://fspace.edu.vn/?page_id=27. Decoded data can be submitted to us via the telemetry decoder or by sending to me directly (thuvt at fpt.edu.vn), audio records are highly appreciated. 


Please feel free to send me a message if there is any question. We would really appreciate your kind support!
