A new release of C-Nav’s C-Monitor includes a full Quality Control (QC) display feature. The QC solution, specifically tailored to meet the demands of C-Nav’s real-time Precise Point Positioning service, uses a statistically sound RAIM algorithm to detect, identify and eliminate data outliers, then reports the rejection process via NMEA and binary messages. The RAIM algorithm incorporates the latest analytical techniques and is the most comprehensive developed to date. After eliminating outliers, the process performs statistical analysis on the remaining observations using techniques that comply with IMO/NMEA requirements and exceed UKOOA recommendations.
