The working group Algorithms and User Terminals is engaged in the development of algorithms for navigation receivers and their implementation in SW and FPGA. Applications are primarily in professional and safety-of-life areas, e.g. in aviation and maritime navigation. Special emphasis is placed on the detection and reduction of propagation errors and radio interfererence as well by advanced signal processing as by adaptive control of array antennas with digital beam forming. For practical testing of these techniques a GNSS SW receiver and together with the antenna working group a real-time multi-antenna GPS/Galileo receiver have been developed. Additionally, different software simulation environments and an advanced GPS/Galileo hardware simulator are used. Another key topic of work is the signal design for future satellite navigation systems.
