Compatibility and interoperability are the main developed directions for the future of GNSS. The B2a signal transmitted by BDS-3 will interoperate with GPS L5 signal and Galileo E5a signal. The performance of interoperable signals will directly affect the performance of user receivers. This paper systematically analyzes and assesses the interoperability of B2a/L5/E5a signals. By briefly introducing and analysis the signal systems and key technologies interoperability, the theoretical basis of the performance assessment of the interoperable signals is laid down. The interoperability performance is mainly assessed from two aspects: signal character and service performance. In terms of signal character, the same carrier frequency, chip rate, and signal bandwidth are selected for the interoperable signals, and the similar signal modulation method is adopted to realize low power consumption, small size, and low cost of the receiver terminal. Seeing from the service performance, through the unification of coordinate and time reference systems, interoperable signals achieve better performance in the accuracy, continuity, and availability than the single-system signal, and achieve the design goal of interoperable signals.
