Always-on satellite positioning receiver

摘要

A method to establish a position of a device receiving an input signal containing data from a plurality of satellites is disclosed. The method generally includes the steps of (A) calculating (i) an estimated position of the device and (ii) an estimated velocity vector of the device, (B) calculating a plurality of estimated locations of a plurality of pseudo-random code sequences in the input signal based on (i) the estimated position and (ii) the estimated velocity vector and (C) generating the position in an output signal based on the pseudo-random code sequences.
