A novel peer to peer aided acquisition strategy tailored to Galileo E1 receivers

Aim of this paper is to investigate the benefits of different P2P aiding information related to the satellites in view on an acquisition strategy tailored to Galileo E1 receivers. The basic idea is to perform an aided acquisition, suitable to a mass-market receiver, based on a secondary code wipe-off on the received signal and exploiting the periodicity of the primary code in order to reduce the computational complexity. This strategy is presented in the paper from the theoretical point of view, discussing the benefits of different aiding information and providing also some preliminary simulation results. In detail the analysis has been focused on the performance degradation in presence of an imperfect wipe-off due to time assistance errors.
