快速捕星和定位是研制高动态GPS(Global Positioning System)接收机所必须解决的一项关键技术.本文主要讨论了GPS星有效历书的推算和接收机接收到的GPS信号的载波多普勒频移各组成部分对接收机的星捕获时间的影响.提出了一种大大缩短GPS接收机的温启动时间的方法.

Quick acquisition of satellites signals and positioning is a key technology in the high dynamic GPS receiver's research and development.In this paper

the method for estimating valid almanac for the GPS satellites is introduced

and for the received GPS signals how the Doppler shift components impact the satellites signals acquisition time are analyzed.On the basis of above

a new algorithm for satellites signals quick acquisition is proposed

which can efficiently shorten the warm start time for the GPS receivers.
