摘要： 近年来频发的全球卫星导航系统（GNSS）欺骗事件，引起了各国对GNSS信号欺骗防护的关注，导航电文认证（NMA）作为民用信号系统级的解决方案，对生成式欺骗攻击具有较好的防护效果。伽利略（Galileo）卫星导航系统在2016年首次提出导航电文认证方案，并于2021年正式发布了公开服务导航电文认证（OSNMA）测试信号。针对OSNMA服务的性能测试，首先对Galileo导航电文认证技术和终端的认证流程进行了阐述，然后利用GNSS接收机开展了关键性能指标的技术试验与仿真。结果表明，OSNMA服务各项指标符合预期，其交叉认证的选星策略具有一定的参考性。研究成果可为中国北斗导航系统（BDS）未来电文认证服务的设计提供支持。

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）.
