Title:
SIMULATION TEST METHOD FOR MULTI-POINT POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/088344
Kind Code:
A1
Abstract:
A simulation test method for a multi-point positioning system, the multi-point positioning system comprising: monitoring software that may control an analog simulation environment; a signal generator that acquires a corresponding transmission parameter and converts same into an actual analog signal; a clock source for providing a high-precision clock frequency signal; and a delayer that delays a transmission signal according to the high-precision clock signal and configuration parameters. The analog signal is subjected to different delays so as to be adjusted according to the monitoring software, and is sent to receiving stations of multiple multi-point positioning systems. The positioning error of the system is evaluated by comparing the deviation between the position of the analog signal and a calculation result of a central station, which solves the problem in which the performance of the multi-point positioning system cannot be fully analyzed and tested before construction and installation. By means of establishing a physical simulation test platform of the multi-point positioning system in a laboratory, the system may be not restricted by factors such as space and time while simulating the real system operating environment to the greatest extent.
