Description
technical field [0001] The invention belongs to the technical field of test and measurement, and relates to a remote measurement data receiving device. Background technique [0002] In recent years, with the rapid development of my country's aerospace technology, the performance of spacecraft has become stronger and stronger. With the application of features such as supersonic speed and long-distance cruise, the parameters and sampling rate of spacecraft telemetry have greatly increased, resulting in the need for data transmission of spacecraft telemetry data at a higher bit rate. At present, in the ground test stage of spacecraft components, the ground telemetry station uses wireless reception to receive high-bit-rate telemetry data, which is extremely susceptible to interference from the space electromagnetic environment, resulting in a large-scale loss of telemetry data, which affects the accuracy of each part of the spacecraft during the test. The analysis of the workin...
