Abstract

The invention provides a distributed broadband communication constellation ground test verification system adapting to multiple scenarios, including the environmental channel simulation subsystem and other subsystems, wherein: when each subsystem is deployed in different regions, the matching environmental channel simulation The received signal is simulated; the time synchronization between each subsystem is performed through the common-view receiver; each subsystem transmits the digital intermediate frequency signal of the transmitted signal directly to the environmental channel simulation subsystem at the receiving end through optical fiber, and Simulate the delay and dynamics of the real signal through the environmental channel simulation subsystem at the receiving end; at the same time, the environmental channel simulation subsystem filters the digital intermediate frequency signal through a high-order filter to simulate the signal distortion in the real environment, and through digital-to-analog conversion and RF signal up-conversion to generate a real RF signal.

Description

technical field [0001] The invention relates to the technical field of communication satellites, in particular to a multi-scenario distributed broadband communication constellation ground test verification system. Background technique [0002] Before the construction of large-scale satellite constellations, it is necessary to build a ground test verification system to conduct multi-level and multi-level verifications such as key technology verification, system verification, interface verification, and application scenario verification, so as to provide preliminary technical support for the construction of satellite constellations. After the satellite constellation is completed, the ground test verification system is required as a ground troubleshooting platform for on-orbit satellite faults and a ground verification platform for on-orbit software or system updates. At the same time, the ground test verification system can be used as a shared open laboratory to provide an exp...
