An Adaptive Acquisition Algorithm of GNSS Receiver

Abstract:

The application of GNSS is very extensive now and soft-radio technology based GNSS receiver is the trend of GNSS receiver product. In which the function of GNSS sigal acquisition is completed by running software and it will impact the performance of the receiver. Now, there are lots of achievements about GNSS sigal acquisition algorithm,but those achievements have big limitations such as the parameters of acquisition algorithm cant be adjusted according to the running condations adaptively and it cant give attention to two or morethings such as speed and sensitivity. Therefore,a algorithm that can adjust parameters of GNSS sigal acquisition algorithm adaptively according to running condations is put out in this paper. Finally, It is testified that the algorithm put out can give attention to two or morethings such as speed and sensitivity.
