Such an efficient cooperation is essential especially for the development of PRS receivers, which is associated with time-consuming processes related not only to security accreditation and certification but also to the subsequent integration of navigation equipment in dedicated platforms with specific environmental and security requirements. Further the use of PRS is ¬ in contrast to GPS PPS ¬ not only limited to military users, but also allowed for other governmental or governmental authorized users. Most of these “new” user communities do not have the same level of experience with security-related equipment as the military users; therefore, a dedicated security-architecture has to be chosen to allow a user-friendly handling of PRS-receivers.
The technological objective of BaSE project is to develop a flexible and scalable high-performance Galileo PRS prototype receiver. Special attention is given to robust acquisition and tracking of the BOCc-modulated PRS signals. Effective suppression of jamming and interference is achieved by combining different approaches like application of an adaptive, two frequency antenna array with a post-correlation beamforming. Further objectives are a robust PVT solution (Position-Velocity-Time) with multi-frequency RAIM (Receiver Autonomous Integrity Monitoring) and spoofing detection by estimating direction of arrival.
