Title:
TEST APPARATUS, SYSTEM AND METHOD FOR SATELLITE RECEIVER
Document Type and Number:
WIPO Patent Application WO/2021/103219
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of testing. Provided are a test apparatus, system and method for a satellite receiver. The test apparatus comprises a satellite signal receiving module, a signal switching module, a signal analog module and a signal attenuation module, wherein the satellite signal receiving module is used for receiving a real satellite signal; the signal analog module is used for generating an analog satellite signal according to a generation control instruction of an upper computer; the signal switching module is used for switching the real satellite signal and the analog satellite signal according to a switching control instruction of the upper computer; and the signal attenuation module is used for adjusting, according to an adjustment control instruction of the upper computer, the power of the signals input by the signal switching module. A real satellite signal is received by means of a built-in satellite signal receiving module, an analog satellite signal is generated by means of a signal simulation module, and the switching between the real satellite signal and the analog satellite signal is performed according to a control instruction of an upper computer, such that automatic switching between an analog signal test environment and a real signal test environment is realized, thereby improving the test efficiency.
