FITSAT-1 and four other CubeSats were deployed from the Internatonal Space Station (ISS) on October 4, 2012. Three of them, WE-WISH, TechEdSat and F-1 have already de-orbited. All of the CubeSats were 1U in size (10x10x10 cm, 1-1.2 kg) except for RAIKO which is a 2U CubeSat twice the size and mass (20x10x10 cm, 2 kg).

Masahiro Arai JN1GKZ has produced a chart showing the decline in altitude of the five CubeSats and compares them with the far larger ARISSat-1 satellite deployed from the ISS on August 3, 2011.

As well as the CW telemetry beacon on 437.250 MHz FITSAT-1 also has a 1200 bps AX.25 packet radio transmitter on 437.445 MHz,  a high-speed (115.2 kbps) data transmitter on 5840.0 MHz and has flashed Morse code to observers on Earth using an LED array.

Takushi Tanaka JA6AVG requests that radio amateurs listen out for the CW telemetry beacon of FITSAT-1 on 437.250 MHz (+/- 10 kHz Doppler shift) during the last few days. Reception reports should be emailed to: tanaka at fit.ac.jp

The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. As well as the optical LED experiment the satellite carries several amateur radio payloads: a CW beacon on 437.250 MHz, a telemetry beacon on 437.445 MHz and a high-speed data downlink on 5840.0 MHz.

Amateur Radio Satellite to Flash Morse Code on Christmas Eve

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

On Christmas Eve (Dec. 24) the Japanese students who built FITSAT-1 are planning to active the satellite’s LED optical array and flash a message in Morse code to Earth. The Morse message may be visible to the unaided eye.

According to Takushi Tanaka JA6AVG the students plan to start testing the optical system at the end of November.

The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. In addition to the LED array it also has a CW beacon on 437.250 MHz, a data link on 437.445 MHz and a 5840.0 MHz data downlink.
