Embodiment Construction
[0053] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0054] At present, mainstream satellite navigation signal acquisition and playback products and many inventions in the market integrate signal acquisition and playback functions, but the acquisition function has higher technical requirements and more complicated design, resulting in high cost. In typical applications, after collecting various typical scene signals, the receiver (including GNSS SoC chip) verification needs a lot of repeated playback to verify the function and algorithm implementation of the receiver (including GNSS SoC chip). To verify the implementation of the receiver algorithm, replay the satellite navigation signal By comparing the calculation results of the baseband processor in the receiver and ...
