Satellite Navigation Usability Monitoring Technology
-
摘要: 随着全球卫星导航系统（GNSS）的不断完善和在各领域的不断推广运用,导航系统的重要性日益增大,导航系统是否可用,直接影响到用户的体验甚至用户的安全.本文论述了卫星导航系统可用性监测相关技术,主要从卫星系统完好性监测、电离层闪烁监测技术和电磁环境监测三个方面分别进行论述.Abstract: Existing navigation and positioning systems include GPS, GLONASS, GALILEO, BEIDOU navigation system, collectively referred to as GNSS. With the continuous improvement of GNSS and the continuous promotion and application in various fields, the importance of navigation system is increasing. The satellite navigation usability directly affect the user experience and even the security of the user. The paper mainly discusses the related technologies of satellite navigation system usability monitoring, mainly from three aspects: satellite navigation system integrity monitoring, ionospheric scintillation monitoring technology and electromagnetic environment monitoring.
