AI Technical Summary
Existing spaceborne equipment testing systems have poor versatility, maintainability, and expandability, and cannot simultaneously meet multiple functional performance requirements. They also have a limited number of communication data interfaces, making it difficult to support both Ka-band TDD and FDD communication modes, and they cannot provide high-precision reference clocks and local time information.
A multifunctional integrated ground testing system for spaceborne equipment was designed, including an integrated management module, a telemetry and data processing unit, an interface forwarding simulator, a Ka converter, an RF link network, and power supply equipment. It supports multiple functional performance test items, has the capability to verify 16-channel payload networking communication, and adopts a rubidium clock design to provide a stable clock reference source.
It enables simultaneous testing of multiple onboard devices under test, supports TDD/FDD communication, has strong maintainability and fault detection capabilities, meets the power supply and data interaction requirements of 16 devices, provides high-precision clock and time information, and ensures the integrity and reliability of the test.
