Design of inter-satellite ranging system based on dual one-way ranging method

Firstly, the ranging requirements of the project which is an interferometer array made up of nine satellites in a lunar orbit is introduced. The CRS system is based on the principle of dual one way ranging measurement, its hardware design and software design are described.

In hardware design, frequency division multiplexing technology (FDM) is adopted to realize the communication among the formation satellites. Closed-loop clock displine technology is conducted to reallize clock synchronizaiton among formation satellites. The CRS design is verifed by series ground tests including wired ranging test on the desk, wireless ranging test in a microwave anechoic chamber, and wireless ranging test with a vehicle.
