    Abstract:

    To comprehensively evaluate the services provided by the BeiDou Navigation Satellite System(BDS-3),a concept of Quality of Service(QoS) in network communication is introduced and then a QoS hierarchical model is proposed.A preliminary classified evaluation index design is given,covering BDS-3 services of Radio Navigation Satellite Service(RNSS),Satellite-Based Augmentation System(SBAS),Precise Point Positioning(PPP),Regional Short Message Communication(RSMC),Global Short Message Communication(GSMC),Search and Rescue(SAR) and Ground Augmentation System(GAS).Then the service guarantee mechanism and parameters mapping relationship are analyzed,thus to provide a way to optimize multiple QoS indicators in complex conditions and quickly locate the source of the fault in abnormal conditions.The research results are expected to provide references for the comprehensive evaluation of BDS performance.
