A Low Cost GPS Adaptive Antenna Array

José M. Blas, Raúl Blázquez and José I. Alonso

Abstract:	Sensibility of the standard GPS receivers to multipath and interferences is one of the main drawbacks to use GPS in high accuracy and availability aplications. Array processing is one of the best mitigation techniques, already used in other CDMA communications systems. In this paper, a low cost GPS adaptive antenna array has been developed. The receiver use base band real time array processing avoiding some of the problems associated to RF beamforming. The design and implementation of the different parts of the receiver, from the patch antenna elements to the signal processing including the radiofrequency (RF) and intermediate frequency (IF) stages, are described. The built prototype incorporates only low cost components that make it suitable for multiple aplications. Experimental data showing the performance of the prototype are presented too.
