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 ...

Abstract

The invention relates to a satellite navigation baseband signal playback device, and an automatic verification system and method. The device is characterized in that one end of a peripheral interfacecontrol chip is connected to an upper computer, and the other end of the peripheral interface control chip is connected to a microprocessor through a peripheral interface; an input end of a USB control interface is connected to the upper computer, and an output end of the USB control interface is connected to the input end of a multi-channel data selector through an IO data interface; the input end of the multi-channel data selector is also connected to an antenna through a radio frequency front end; the output end of the multi-channel data selector is connected to a baseband processor, and the baseband processor is connected to the microprocessor; and a selection control signal of the multi-channel data selector is from the microprocessor. In the invention, through simplifying a function,a satellite navigation baseband signal playback function is only realized, a low-cost satellite navigation baseband signal playback device is realized through a mature, stable and low-cost interfacedata playback board and a chip verification board, and a hardware condition is provided for an automatic test of playback data.

Description

technical field [0001] The invention relates to the field of receiver chip design in the satellite navigation field, in particular to a satellite navigation baseband signal playback device, an automatic verification system and a method. Background technique [0002] GNSS (Global Navigation Satellite System, Global Navigation Satellite System) has made great contributions to the advancement of the informationization process of human society. The time and space services it provides, such as positioning, navigation, measurement, and timing, have profoundly affected all walks of life and become the new generation of today. core elements of information technology. For example, in the field of intelligent transportation, through the introduction of satellite navigation technology, functions such as vehicle positioning, anti-theft, anti-robbery, driving route monitoring and call command have been realized. The GNSS receiver is an instrument or terminal module that receives GNSS sa...
