DGPS QC package

  04/05/2009
A release of C-Nav's C-MONITOR includes a full Quality Control (QC) display feature. The QC solution, specifically tailored to meet the exacting 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.
 

 

After eliminating outliers, the process performs statistical analysis on the remaining observations using techniques that comply with IMO/NMEA requirements and exceed UKOOA recommendations.

 

C-MONITOR is user-configurable and includes a table of GPS satellite statistics with real-time displays from single or multiple GPS receivers and time series plots of differential age and a number of satellites in the solution.

 

A sky plot of all visible GPS/GLONASS satellites (with status) is provided with variable scale scatter plots for monitoring satellite position stability. The additional QC parameters include unit variance, F-test of Unit Variance, 67% error ellipse (NMEA) and 95% error ellipse (UKOOA).

 

The reliability statistics include outlier rejection, type-II error probability, W-statistic (for each satellite in solution) and marginally detectable error (range and position).

MCA on Surveying the British Coast

Rob Spillard explains how the MCA is conducting hydrographic surveys, including the history of British hydrographic surveying, latest developments in technology and wreck research projects, sometimes accompanied by a BBC TV camera crew. This movie includes an example of the discovery of two sunken WWI submarines off the Orkney Islands.
