The invention provides a spacecraft measurement and control digital transmission signal processing and data distribution device, including: a main control module, which is used to communicate with the spacecraft comprehensive test system outside the device and the measurement and control signal processing module and the digital transmission signal processing module in the device. Data interaction; CPCI bus, used to carry the data interaction between modules; measurement and control signal processing module, connected to the main control module through the CPCI bus, used to process the remote control, telemetry and ranging signals using the unified carrier measurement and control system; The digital transmission signal processing module is connected with the main control module through the CPCI bus for digital transmission signal processing; the power splitter is used to receive the modulated signal outside the device, divide it into two signals with equal power, and send them to the measurement and control signal processing modules and digital signal processing modules. The device of the invention has both the functions of measurement and control signal processing and data distribution, as well as the functions of digital transmission signal processing and data distribution, and can realize the integrated processing of measurement and control and digital transmission signals.
Description
technical field [0001] The present invention relates to the technical field of spacecraft testing, in particular, to a spacecraft measurement and control digital transmission signal processing and data distribution device and its communication method, especially to a spacecraft measurement and control digital transmission signal processing and data distribution device and its integrated test system with a spacecraft The method of communication between the measurement and control test subsystem and the digital transmission test subsystem. Background technique [0002] With the prosperity and development of my country's aerospace industry in recent years, the types and numbers of spacecraft continue to increase, and the tasks tend to be diversified. The existing design scheme of separating the measurement and control system from the data transmission system is not conducive to satisfying the requirements of certain space missions on weight, volume, and power. Therefore, some ae...
