China’s Harbin Institute of Technology is developing a pair of lunar-orbiting satellites — DSLWP-A1 and A2. According to Mingchuan Wei, BG2BHC, DSLWP is “a lunar formation-flying mission for low-frequency radio astronomy, Amateur Radio
The Amateur Radio
The satellites are 50 × 50 × 40 centimeters, with a mass of about 45 kilograms and are 3-axis stabilized, with two linear polarization antennas. The team has proposed downlinks for DSLWP-A1 on 435.425 MHz and 436.425 MHz; downlinks for DSLWP-A2 would be 435.400 MHz and 436.400 MHz, using GMSK with concatenated codes or JT65B. Harbin Institute of Technology also developed the Lilac series of CubeSats.
