[en] Analysis of the benefits and the drawbacks brought by satellite-based positioning in multi-GNSS single-frequency mode. Presentation of DGPS results computed by combining GPS L1 + Galileo E1, GPS L5 + Galileo E5a and Galileo E5b + BeiDou B2 signals. The improvement of the availability, the reliability and the positioning precision are highlighted as benefits of the multi-GNSS solutions. The ISBs affecting high-end receivers are presented as the drawbacks of multi-constellation solutions. Finally, multi-GNSS single-frequency ISBs-fixed solutions are compared to single-GNSS single-frequency solutions.
