Abstract:	With the modernization of GPS and Glonass and the introduction of Galileo and BeiDou, four Global Navigation Satellite Systems (GNSS) will be available in the future. A combined usage of these constellations can result in better performance compared with a single system, also for standalone processing. The algorithmic complexity will increase though, as additional effects have to be taken into account. This paper analyzes different possibilities to handle different GNSS constellations as well as different GNSS signals simultaneously for standalone processing in order to characterize the corresponding benefits. For a theoretical assessment, the dilution of precision is analyzed based on simulated constellations. Additionally, the actual performance of multi-constellation & multi-frequency GNSS is analyzed using recorded data. Based on both assessments, the possible performance of GNSS in the future is predicted.
