Kalman Filtering for Acquisition of GNSS Signals in Highly-Manoeuvrable Receivers

F. D. Nunes, F. M. Sousa and J. M. Leitao

Abstract:	GNSS receivers in highly-manoeuvrable platforms, such as military aircraft and rockets, bear large values of acceleration which prevents the use of simple signal acquisition techniques. Herein, we propose a new approach to the acquisition problem which is divided into two parts: a coarse code delay/Doppler frequency acquisition algorithm followed by a refinement (and validation) algorithm based on two banks of Kalman filters. The first bank allows to obtain estimates of the code delay and the Doppler frequency. The second bank permits to refine the frequency estimates.
