Radio antennas and receivers (Longjiang / Chang’E-4 mission)

As part of the China Chang’e 4 mission, two microsatellites (45 kg each) named Longjiang-1 and Longjiang-2 have been deployed into lunar orbit in May 2018 to observe the sky at very low frequencies (1 MHz-30 MHz), corresponding to wavelengths of 300m–10m, with the aim of studying energetic phenomena from celestial sources. Due to the Earth’s ionosphere, no observations in this frequency range has been done in Earth orbit, offering potential breakthrough science. CBK PAN collaborates with National Space Science Center, Chinese Academy of Sciences with development of the set of antennas and receivers for both satellites. Longjiang-1 has been lost after the launch, Longjiang-2 continues the mission.
