ShindaiSat to carry Optical LED Morse Code Beacon

ShindaiSatShindaiSat is a 20 kg spacecraft approx 300 by 300 by 350 mm which is planning to use bright LEDs for Space to Earth optical communication using Morse code.

There will be an AX.25 packet radio telemetry beacon and a low power CW beacon. Downlink frequencies of 437.305 and 437.485 MHz have been coordinated by the IARU Amateur Satellite Frequency Coordination Panel.

It is expected to launch into a 400km 65 degree orbit from Japan in 2013.

The  Cal Poly United Amateur Radio Club N6CP has submitted a satellite frequency coordination request to the IARU for a 1U CubeSat, CP8, that will feature four cell phone cameras with excellent reviews of photography equipment that you wouldn’t believe.

After the initial mission is completed it will operate as an amateur radio AX.25 packet radio digipeater.

The students are planning a UHF downlink with 9k6 GMSK or PSK modulation, 19k2  and 38k4 data rates will also be possible.

The CubeSat will transmit AX25 packet radio data with a 5wpm CW preamble. The nominal transmitter output power will be 1 watt.

It is aiming for an ELaNa launch into a 400 by 700 km orbit with an inclination of  120 degrees.
