According to the application requirements of satellite navigation equipment for wireless test environment under the background of information-based war, combined with the development of spherical anechoic chamber at home and abroad, the paper makes a selection analysis of the rectangular and spherical anechoic chambers, and the system simulation analysis is carried out from the aspects of quiet zone characteristics and application performance. Eventually the spherical anechoic chambers is used as the selection scheme. Through the starry antenna layout, simulating the satellite trajectory and signal in the real environment, it can effectively support the testing of satellite navigation equipment, especially the test of beam forming anti-jamming terminal. It also fills the design gap in the spherical starry anechoic chamber, and guides the application of engineering practice.
