Signals from Lunar Orbit

Post by MrWeetabix » 22 May 2018, 08:34

Two 47kg micro satellites hitched a ride on a Chinese rocket on Sunday night and are currently in a Lunar Transfer orbit, with an eventual elliptical lunar orbit the ultimate aim.

Onboard each satellite, there are two VHF/UHF SDR transceivers (about 2w TX power) to provide beacon, telemetry, telecommand, digital image downlink and a GMSK-JT4 repeater.

Satellite A will transmit 500 baud GMSK with 1/4 turbo code on 435.425 MHz and 250 baud GMSK with 1/2 turbo code and precoder on 436.425 MHz, and satellite B will transmit 500 baud GMSK with 1/4 turbo code on 435.400 MHz and 250 baud GMSK with 1/2 turbo code and precoder on 436.400 MHz, in every 5 minutes by default. Each transmittion will last about 16 seconds.

QSL cards will be issued for those whom are that way inclined. More details from the mission website - https://amsat-uk.org/2018/05/19/dslwp-s ... nar-orbit/
