Wei Mingchuan BG2BHC reports DSLWP is a lunar formation flying mission for low frequency radio astronomy, amateur radio and education, consists of two microsatellites.
Developed by students at the Harbin Institute of Technology the amateur radio payload onboard DSLWP-A1 will provide telecommand uplink and telemetry / digital image downlink. An open telecommand is also designed to allow amateurs to send commands to take and download an image.
The satellites are 50x50x40 cm with a mass of about 45 kg and are 3-axis stabilized. Two linear polarization antennas are mounted along and normal to the flight direction.
The team plans downlinks for A1 on 435.425 MHz and 436.425 MHz while downlinks for DSLWP-A2 would be 435.400 MHz and 436.400 MHz using 10K0F1DCN or 10K0F1DEN 250 bps GMSK with concatenated codes or JT65B.
Planning a launch into a 200 x 9000 km lunar orbit in June 2018. Further info at http://lilacsat.hit.edu.cn/
