- W2350420711 abstract "To solve the quick acquisition problem of the highly dynamic global positioning system(GPS)receiver,the quick acquisition method based on field programmable gate array(FPGA)is proposed.This method uses multichannel parallel code phase acquisition.The principle of code phase hunting algorithm is analyzed;and the same with its implementation.The influence of signal receiving channels on satellite hunting time is discussed and then the correlating method,in which GPS receiver channels were extended to guarantee simultaneous hunting of all satellites,is proposed.Based on FPGA,the quick acquisition method is realized,in which 32 parallel channels were combined with parallel code phase hunting algorithm.The experimental results indicate that the above quick acquisition method is feasible.The hunting time under cold start is less than 0.5s.Compared with the traditional serial acquisition mode,the speed has improved significantly;and the real-time positioning could be implemented with highly dynamic GPS receivers based on FPGA." @default.
