Space base and ground base integrated wireless communication test method based on Ka band

Abstract

The invention proposes a space base and ground base integrated wireless communication test method based on a Ka band. The method comprises the following steps: selecting a loading flight platform, assorting space and ground equipment installation windows, designing ground-based telemetry and security control communication links, designing forward and return communication links of a space base, designing a communication link antenna pointing angle of a ground base, designing the communication link antenna pointing angle of the space base, determining a flight path, designing a reserved capturepoint, performing space base and ground base telemetry and collaborative guidance, and performing space base and ground base telemetry and collaborative control. The method is a technical approach that can be directly applied to realize integrated wireless communications in the Ka-band space base and ground base integrated wireless communication in a carrier environment of a spacecraft, and particularly meets the real-time coordinated communication of space base and ground base at the Ka band and the multi-system and multi-functional communication requirements, and the space base and ground base integrated wireless communication test method can achieve the functions of space base forward spread spectrum telemetry, space base return spread spectrum telemetry, ground base frequency modulation high code rate telemetry, ground base spread spectrum external survey, ground base spread spectrum telemetry, ground base spread spectrum guide beacon and ground base spread spectrum low code rate telemetry.

Description

technical field [0001] The invention relates to a space-ground-based integrated wireless communication test method based on the Ka frequency band, belonging to the field of wireless communication. Background technique [0002] refer to figure 1 Schematic diagram of the spacecraft-space-ground-based wireless communication scheme in the prior art. At present, the realization of spacecraft wireless communication usually adopts independent design of space-based and ground-based channels. The communication frequency band is the traditional S-band. Most spacecraft only have ground-based communication capabilities. About 2Mbps. Space-based communication is limited to the back spread spectrum telemetry function, and its code rate is about 256Kbps. The traditional S-band ground-based 2Mbps telemetry is to send the main status information and measurement information of the spacecraft to the ground through wireless equipment. Measurement coverage. [0003] The above-mentioned spac...
