Small satellite measurement and control system and method suitable for deep space exploration

Abstract

The invention discloses a small satellite measurement and control system and method suitable for deep space exploration. The system and the method solve the problems of a typical measurement and control scheme of a small satellite platform for deep space measurement and control, including the problems that the antenna array has an interference area, effective all-directional radiated power and received sensitivity are insufficient, the electromagnetic self-compatibility of the system is insufficient, the differential unidirectional ranging function of high-precision orbit determination is notsupported and the like. The system and the method can meet the measurement and control requirements of deep space control and measurement tasks, furthest reduce the redundancy of equipment, and can back up and switch measurement and control channels under the dedicated logic coordination of satellites to ensure the reliability of the measurement and control system. By improving the design for deepspace flight tasks, the system and the method are not limited to small satellite platforms, but also have reference significance for other deep spacecrafts.

Description

technical field [0001] The invention relates to a small satellite measurement and control system and method suitable for deep space exploration, belonging to the technical field of deep space satellite system measurement and control. Background technique [0002] Due to the development of deep space exploration technology in recent years, the satellite platform is required to ensure the effectiveness of the measurement and control link and the coverage of the measurement and control range during the whole mission process. The current typical S-band unified carrier measurement and control system cannot meet the measurement and control requirements of deep space exploration missions. , so it is necessary to develop a measurement and control system suitable for deep space exploration on the small satellite platform. [0003] The measurement and control technology of deep space probes has been gradually applied in orbit in the Chang'e exploration mission, but it is the first tim...
