GALANT

Future navigation services provided by upcoming satellite systems like Galileo will require corresponding improvements of the receiving systems. Particularly, interference and multipath signals may cause a significant degradation of the performance and thus make it impossible, to obtain exact and reliable positioning data. These restrictions and uncertainties cannot be tolerated for Safety-of-Life (SoL) applications e.g. in aeronautics and shipping. In order to overcome this problem, adaptively steered antenna arrays are employed, which enable the use of new beamforming and signal processing algorithms. They provide a more exact and reliable navigation solution, by suppressing interferences and multipath signals and improving the reception of the information signal from the direction of the satellite.
