Abstract

A positioning system obtains an estimate of the heading of a body whose position or velocity is to be estimated, for example from a heading sensor such as a gyroscope or accelerometer. Respective signals are tracked from a plurality of transmitters, and a respective Doppler measurement is obtained from each of said tracked signals. For each of the tracked signals, a speed of the body is estimated using the estimate of the heading of the body and the respective Doppler measurement. It is then determined whether the estimated speed of the body is consistent with the signal having been received along a direct path from the transmitter. Signals that provide information about the speed of the body that is inconsistent with the signal having been received along a direct path from the transmitter are then disregarded when estimating the position or velocity of the body.
