STAP Performance and Antenna Miniaturization in Multi-Antenna GNSS Receivers

Nowadays GNSS receivers are required to operate in miniaturized system and platforms, such as UAV. Two miniaturized GNSS antenna arrays -formed of four L1 band capable elements and one tetra-band capable element- are presented. The antenna arrays not only deliver good positioning estimations but also provide robustness against interference signals. Real measurement positioning performance results are shown. In addition, the interference mitigation performance of the two arrays is investigated and assessed using Spatial Temporal Adaptive Performance (STAP) algorithm simulations.
