Abstract
The disclosure provides a GNSS receiver. The GNSS receiver a measurement engine that generates a set of doppler measurements and a set of pseudo ranges in response to an input signal. A clock frequency drift estimation (CFDE) block receives the set of doppler measurements, and generates an averaged delta doppler. A position estimation engine estimates a position and velocity of a user based on the set of doppler measurements, the set of pseudo ranges and the averaged delta doppler.
