Abstract

The Global Positioning System (GPS) is widely used for many applications but its performance can be impacted significantly by the environment. This can be overcome to a large extend by processing the signal in space and time. The space processing is achieved with a seven element planar array followed by an algorithm to calculate the antenna weights in such a way that the interferences can be nulled. The time processing is implemented with uniformly-spaced tap delays. This paper reports some alternatives to improve the performance of the system. First, a spherical array replaces the present planar array to increase the line-of-sight (LOS) at low elevation angles. Then, the tap delay spacing is incorporated. Results show an improvement in the bit-error-rate (BER) performance when non-uniformly spaced taps are used.
