The evolution of lunar communication—From the beginning to the present

International Journal of Satellite Communications and Networking, Volume 42, Issue 3, Page 200-216, May/June 2024.
Since the beginning of the space age, the Moon has been the target of many missions from the 1950s to the present day. Radio communication plays a fundamental role in space vehicle projects because this is the most obvious way to communicate with the ground station and transmit control commands and scientific data.

A Design Method for Redundant Microthruster Layout With Allocation Error

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
The microthruster is generally chosen as the actuator of the drag‐free satellite control system, and the layout directly affects the stability of the satellite control. Due to the extremely rigorous objectives of drag‐free control, a design method for the redundant thruster layout is proposed in this paper to improve the control stability of the ...
