The C-Monitor application provides a graphical interface for supervising the operation and performance of one or more differential GNSS systems. It is compliant with the latest QA/QC guidelines for GNSS positioning within the oil and gas industry per the International Association of Oil and Gas Producers (IOGP) and the International Marine Contractors Association (IMCA).

The guidelines allow for pre-set user-defined alarm settings or limits, which can be set using the C-Monitor application.

• Fully user-configurable
• Complies with National Marine Electronics Association (NMEA) requirements
• Complies to the OGP/IMCA guidelines for GNSS positioning in the oil and gas industry
• Complies with IMO Receiver Autonomous Integrity Monitoring (RAIM) standards: Unit variance, F-test, Error ellipse, Rejected SV error details, Marginally Detectable Error (MDE)
• User configurable alarms and warnings (green, yellow, and red status information)
• Sky plot of all visible GPS/GLONASS satellites, their location, orientation, and health
• Variable scale scatter plot monitors GNSS position stability
• Table of GNSS satellite elevation, azimuth, and signal strength
• Real-time display of position information from a single or multiple GNSS receivers
