Zhigang, Wang Xue, Su Mudan, Zhu Yongxing, Ren Xia, Zhang Huijun, Song Shuli, Wang Kai, Wang Weijia: Global Continuous Monitoring and Evaluation System (iGMAS) Monitoring and evaluation parameters1 ScopeThis standard specifies the global continuous monitoring and evaluation system (iGMAS) to the global navigation satellite system (GNSS) operating status, service performance The classification of monitoring and evaluation parameters involved in monitoring and evaluation, constellation state parameters, space signal parameters, space information parameters, service performance parameters Number and other requirements: This standard applies to satellite navigation system engineering construction and operation maintenance, as well as civil aviation, maritime, transportation, power, communications and other industries to satellites Monitoring and evaluation of navigation service performance:2 Normative referencesThe following documents are indispensable for the application of

GB/T 39267-2020 Beidou satellite navigation terminology 3 Terms, definitions and abbreviations 3:1 Terms and definitions The following terms and definitions defined in GB/T 39267-2020 apply to this document: 3:1:1 Healthstatusofsignal-in-space The status parameter used in the navigation message to indicate whether the space signal is normal: 3:1:2 Signaloutages Navigation satellites cannot broadcast space signals whose status is "healthy": Note 1: The space signal includes the signal is not broadcast, broadcast non-standard codes, and the signal status is "unhealthy": Note 2: Signal interruption includes planned interruption and unplanned interruption: 3:1:3 Scheduled suspensions When the satellite signal is expected to not meet the performance specified in the ICD document, the satellite signal that has been notified in advance is interrupted: 3:1:4 Unscheduled outages Satellite signal interruption caused by system failures or maintenance events other than planned interruptions: Note: Users should be notified as soon as possible after an unplanned outage occurs: 3:2 Abbreviations The following abbreviations apply to this document: BDS: BeiDou Navigation
