Method and system for improving the Time To First Fix of satellite positioning system

摘要

(106), and a satellite positioning system (SPS) antenna support device (100) includes a processor (104) environment sensor for determining (102), the azimuth value SPS receiver, an acceleration value or tilt value. Based on the environmental data and the estimated direction (304), the peak antenna gain, wherein the processor, in view satellites to determine an estimated orientation of the peak antenna gain (306), for satellites in view to determine the orientation can be programmed to give priority to acquisition attempts part of the (308) as. The processor can perform a split search by dividing the correlators to search for satellites to search for the satellite with a hypothetical peak gain, by using shorter residence times, have lower gain, to use a longer residence time (310). Based on the estimated direction of the peak antenna gain, can be presented electronically orientation guide the user in consideration of the orientation of the SPS receiver wherein the device (312).
