Test procedure 9 Clause Samples

Test procedure 9. For: KPI_009: Accuracy of position KPI_013: Success rate of heading information The existing eCall standardization calls for the sole utilization of the GPS system for position estimation. The GPS position determination process comprises the position uncertainty estimation algorithm that provides a fair estimation of horizontal, vertical and timing error. Those estimates are available in real-time via standardized NMEA-0183 interface, applied in modern GPS receivers. Preconditions: 1) IVS A GPS receiver is required. Utilization of a SBAS / EGNOS- enabled or combined GPS+EGNOS / GLONASS receiver is an advantage. Access to NMEA data stream using a dedicated application, or access to internal NMEA stream log is needed.
