First picture from FITSAT-1 on 5840.0 MHz
When the FITSAT-1 CubeSat was deployed from the International Space Station on October 4 it took a picture using the on-board camera. On Friday, October 19 UT, the team successfully downloaded the picture using the high-speed 115.2 kbps data transmitter on 5840.0 MHz.
FITSAT-1 5840.0 MHz downlink received with FUNcube Dongle
This video by radio amateur Tetsurou Satou JA0CAW shows reception in Japan of the 5840.0 MHz downlink from the FITSAT-1 (aka NIWAKA) CubeSat that was deployed from the ISS on October 4.
He used a 38cm dish with a down-converter to an IF of 1284 MHz, a BGA2717 LNA and the AMSAT-UK FUNCube Dongle SDR with HDSDR software.
The amateur radio CubeSat FITSAT-1 (aka NIWAKA) carries an Optical Communications experiment that aims to write Morse Code across the night sky. The satellite is fitted with a bank of high power LEDs that will be driven with 200W pulses to produce extremely bright flashes that may be visible to the unaided eye.
FITSAT-1 was deployed from the International Space Station (ISS) at 15:44 UT on Thursday, October 4 along with F-1 and TechEdSat.
On Sunday, October 7 Takushi Tanaka JA6AVG provided this update:
We have received a lot of signal and telemetry reports from amsat members. All reports show FITSAT-1 starts working and sound. Thank you very much for your help.
We will examine movements, temperatures, and battery states of FITSAT-1 during these 10 days, and start experiments of 5.8GHz transmission and flashing LEDs.
I will announce the experiments on my web-page http://www.fit.ac.jp/~tanaka/fitsat.shtml
As well as 437.250 MHz and 437.445 MHz (both +/- 10 kHz Doppler) this innovative satellite can also transmit on 5840.0 MHz (+/- 134 kHz Doppler).
FITSAT-1 received with 1/4 wave antenna and FUNcube Dongle SDR
Howard Long G6LVB has released a video showing reception of the FITSAT-1 CubeSat 437.250 MHz CW beacon using just a 1/4 wave antenna on a baking tray sat on his balcony in London. The receiver was a FUNcube Dongle Pro+ LF/MF/HF/VHF/UHF Software Defined Radio (SDR). No preamp or external filtering were used.
NASA Release Amateur Radio CubeSat Deployment Pictures
NASA have released photographs of the amateur radio CubeSats TechEdSat, F-1 and FITSAT-1 taken by an Expedition 33 crew member on the International Space Station (ISS).
