Generalized comprehensive radio frequency measurement and control system for spacecraft

Abstract

The invention discloses a generalized comprehensive radio frequency measurement and control system for a spacecraft, and the system comprises a SAR (synthetic aperture radar), a synthetic radio frequency channel and a synthetic processing terminal. The SAR realizes the integrated conversion between the space electromagnetic wave energy and the energy of the measurement and control system. The synthetic radio frequency channel realizes the conversion between a radio frequency signal and an intermediate frequency signal. The synthetic processing terminal receives the externally inputted telemetry data to form a ground-based telemetry frame, and then sequentially performs coding, modulation and digital-to-analog conversion, and finally transmits the ground-based telemetry frame through the synthetic radio frequency channel and the SAR. The comprehensive radio frequency measurement and control system can integrate the existing functions of telemetry, security control, external measurement,navigation and relay, and integrates independent radio frequency resources and baseband resources to form the generalized comprehensive radio frequency measurement and control system for the spacecraft, thereby greatly reducing the weight, volume and power consumption of the measurement and control system, and improving the system performance.

Description

technical field [0001] The invention belongs to the technical field of spacecraft measurement and control, and relates to a generalized integrated radio frequency measurement and control system for spacecraft. Background technique [0002] In order to meet the needs of rapid launch and efficient delivery of carrier rockets and missile weapons, the spacecraft measurement and control system needs to have multi-task, large-scale, safe and reliable, and space-ground integrated measurement and control capabilities. The traditional measurement and control system adopts a parallel discrete structure design. First, it is divided into independent telemetry subsystems, security control subsystems, external measurement subsystems, navigation subsystems and relay subsystems according to functions. Secondly, the overall technical indicators of the measurement and control system are decomposed into the above-mentioned subsystem technical indicators, and then the independent design of the ...

AI Technical Summary

Problems solved by technology

[0003] Due to the discrete design of the traditional measurement and control system, software and hardware are independently designed for different functions, resulting in the redundancy of a large number of radio frequency resources and baseband resources in the measurement and control system. , Power consumption cannot be reduced

For different launch vehicle or missile weapon measurement and control requirements, the expansion and tailoring of measurement and control functions need to be re-designed independently, and it is impossible to realize the universal design of multi-type spacecraft measurement and control systems
