Abstract :
Of the wide variety of array processors, which are available to GPS receiver designers for noise and RF interference suppression, few achieve good performance and possess well-defined signal preservation properties. We introduce a new optimal array processor for the reception of GPS signals in RF interference and noise, that maximises geometric positioning precision. Comparison with well-known and previously proposed array processors demonstrates a superior reduction of the positioning error from noise and interference residuals. In addition, we derive the processor for optimisation of precision in a single position co-ordinate, such as height, or time; the improvement of vertical precision could be a significant development for the use of GPS in aviation
