摘　　要：卫星信号模拟器作为卫星导航接收机开发与验证的必备工具,其相关理论研究与工程应用具有重要学术意义和巨大商业价值。详细介绍了软件、硬件和混合架构三种卫星信号模拟器的国内外理论研究和产品动态,总结了电离层误差、多径效应等主要误差模型的理论研究进展和应用现状,通过对比指出了国内较国外在模拟器产品、仿真理论特别是误差模型理论研究等方面存在的差距,最后对模拟器发展趋势进行了探讨和展望。As an indispensable tool to develop and verify. GNSS（Global Navigation Satellite System） receivers, the navigation satellite signal simulator has been researched and developed extensively for its academic significance and substantial commercial value. Development and progress achieved in recent years on the theoretical research and products commercialization of satellite signal simulators home and abroad are introduced and studied comparatively, including software simulator, hardware simulator and hybrid structure simulator. New research progress achieved on main interrelated error models such as ionospheric error and multi - path effect is summarized and analysed. Efforts that should be made in China on simulator products development, signal simulation theories study especially those related to error models are pointed out. Finally future trends of the navigation satellite signal simulator are discussed.
