On October 4, 2012 five CubeSats were successfully deployed from the International Space Station (ISS). The first pod containing RAIKO and WE-WISH was deployed at 1437 UT while the second pod containing FITSAT-1, F-1 and TechEdSat deployed at 1544 UT. Pictures can be seen at

October 4 was also the 55th anniversary of the launch of the first satellite Sputnik 1. Videos of Sputnik are here.

Four of the CubeSats carry Amateur Radio payloads, they are TechEdSat, F-1, FITSAT-1, and WE-WISH. As of Oct 5, 1015 UT signals had been reported from WE-WISH and FITSAT-1 as well as weak signal reports for TechEdSat.

Live TV broadcast for launch of HTV-3 CubeSats

FSpace, the team of young engineers and students at the FPT University who developed the amateur radio F-1 CubeSat, report on the final launch preparations for the HTV-3 cargo vessel that will carry five CubeSats to the International Space Station (ISS).

FSpace say final inspection was performed on July 9, and from July 13-15, a rehearsal was conducted simulating the launch operation. Late access cargo loading will continue until July 19 then the hatch will be closed and the H-IIB launch vehicle with the HTV-3 will be moved to the launch pad. The launch is planned for July 21 at 02:18 UT.

FSpace report that live TV coverage will be available at these URL’s:

– NASA TV HD (HD resolution, for high speed connections)

– NASA TV (standard resolution, for lower speed connections)

– Live webcam from Tanegashima launch pad (automatically updated once every few minutes)

–Output power: max 0.3W, half-wave dipole antenna
–Modulation scheme: Morse code beacon (10 chars) using PWM CW
–Beacon interval: every 30 seconds (configurable)

–Frequency: 145.980MHz , FM Narrow
–Power supply: rechargeable battery, operates in the dark by default but can be commanded to operate in sunlight as well
–Output power: max 1.0W, half-wave dipole antenna
–Modulation scheme: AFSK 1200bps, half duplex
–Telemetry interval: one AX.25 packet every 30 seconds (configurable)
