摘要: The acquisition stage in global positioning system receivers provides a coarse estimation of the Doppler shift and code phase incoming signals. accuracy estimation, especially shift, greatly influences subsequent tracking loops. Based on parameter prediction chirp z-transform algorithm, novel approach to acquire accurately is proposed. are predicted first according desired trajectory vehicle satellite ephemeris. Then, frequency refinement code-stripped signal conducted within small interval around by using algorithm. To reduce computational load, data sequence down-sampled with an integrate dump accumulator without degrading performance proposed Results indicate that, only 1 ms sampled data, algorithm can achieve high-frequency accuracy. Besides, pro...
