摘要: In this paper, we explore the adoption of Array Signal Processing in Galileo Ground Stations. The main motivation comes from need efficiently mitigating multipath and interference sources order to achieve centimetre accuracy. One critical aspects appearing when an array antennas is implemented resides on perturbations mismod-elling. For that reason, work places special emphasis issue some robust beamforming techniques are proposed. Differently other studies addressing use conventional for navigation applications, propose novel strategies specially adapted considered scenario. As shown digital allows a (at least) 47% reduction terms tracking errors compared single antenna receiver.
