Determining the spatio-temporal and kinematic parameters of a signal receiver and its clock by information fusion

摘要

Techniques are provided for determining clock doppler of a signal receiver. One aspect of the invention is to divide sampled data received from a receiver into data segments of incremental length. The clock doppler is estimated based on each data segment with respect to all the satellites from a set of satellites that is overhead the receiver. For each data segment, the results with respect to each satellite is used to refine the calculations of the clock doppler with respect to the next satellite. When the clock doppler calculations have been performed using all the satellites from the set of satellites for a particular data segment, then the results with respect to the particular data segment is used to refine the calculations of the clock doppler with respect to the next data segment.
