Abstract
Estimating the position of a receiver using positioning signals and Doppler frequency measurements. Approaches for estimating the position of a receiver using positioning signals and Doppler frequency shift measurements determine an initial estimate of a receiver's position using ranging signals from a first system, generate Doppler frequency shift measurements using the Doppler positioning signals from a second system, and refine the initial estimate using the Doppler frequency shift measurements.
