Abstract:  In recent years,frequent spoofing attacks of Global Navigation Satellite System(GNSS)have aroused the attention of many countries on the protection of GNSS signal.As a system-level solution for civil signal,Navigation Message Authentication(NMA)has a good protection effect against spoofing attacks.Galileo first proposed the NMA scheme in 2016 and officially released the Open Service Navigation Message Authentication(OSNMA)test signal in 2021.Aiming at the performance testing for the OSNMA service,the Galileo NMA technique and the authentication process of terminal were described,then the GNSS receiver was used to carry out the technical test and simulation of the key performance indicators.The results show that the OSNMA indicators are in line with expectations and the star selection strategy of cross-authentication is representative.The research results can provide a reference for the design of the future NMA service in BeiDou Navigation Satellite System(BDS).
