Example Embodiment
[0032] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below with reference to the accompanying drawings.
[0033] The embodiment of the present invention provides a fast acquisition system for GLONASS satellite signals based on FPGA implementation. The acquisition system is used in GLONASS satellite receiver baseband processing, can process the digital intermediate frequency signal after A / D conversion, and quickly calculate the Doppler frequency shift of the intermediate frequency signal relative to the local carrier, and relative to the local code generation The code phase shift of the device.
[0034] One of its core contents is the sampling and data storage unit and part of the matched filter unit. Through special data storage methods and data movement operations, rapid relative sliding between data and local codes is achieved.
[0035] Such as figure 1 , The acquisitio...
