FITSAT-1 5840.0 MHz downlink received with FUNcube Dongle

Reception of FITSAT-1 5840.0 MHz downlink using FUNcube Dongle SDR

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.

FITSAT-1 Update

FITSAT-1 plans to use LED’s to signal in Morse code

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

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).
