Title:
ANECHOIC CHAMBER-BASED REAL SATELLITE SIGNAL SIMULATION APPARATUS AND METHOD, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/087967
Kind Code:
A1
Abstract:
An anechoic chamber-based real satellite signal simulation apparatus and method, a device, and a medium. The apparatus comprises N unified anechoic chamber satellite signal devices; each unified anechoic chamber satellite signal device comprises a navigation signal generation channel capable of outputting twelve simulated navigation signals, and is used for generating 12*N full-system full-frequency point satellite navigation signals according to satellite signal simulation control parameters, and performing on-demand switching and outputting after simultaneously generating current-moment and next-moment satellite navigation signals at a current moment, so as to achieve a continuous and non-hopping phase when signals are outputted. The solution solves the technical problems of complex cascading, high cost, reduced reliability, and discontinuous signal output of existing navigation signal simulation devices.
