Register for the Final Presentation of the NAVISP EL2 -001 Project "COLOSSUS"
COLOSSUS is a new tool to support developers and users of GNSS within application domains that demand the highest levels of performance, including safety, reliability, availability, and dependability. COLOSSUS aims to ensure that GNSS is safe and secure in a formal, structured, and validated manner through continuous monitoring and reporting of performance, faults, failures, errors, outages, and recovery times. These statistics and metrics are vital in enabling GNSS to continue to be pushed to deliver position, navigation, and timing services into the emerging markets of robotics and autonomous systems and within other critical operations.
COLOSSUS is based on continuous processing and analysis of GNSS datasets from CORS continuously operating GNSS receiver sites (CORS). Through this, COLOSSUS can monitor GNSS system and user level performance against defined standards, as well as autonomously identifying, isolating, and attributing GNSS faults and failures into causation groupings.
During the project, GMV have completed the development of the COLOSSUS system, demonstrating continuous, automated real-time processing and fault detection, and routine post-processing to generate performance statistics and report generation for GPS, Galileo and GLONASS constellations. In addition, a number of dedicated COLOSSUS receivers have been deployed at a network of monitoring sites in order to augment data available from existing CORS networks.
The COLOSSUS system is now continuously operating, allowing users to check current status of the GNSS constellation, view user and system performance results, and download performance reports through a dedicated user application. The COLOSSUS product will be used to build up database of probabilities of occurrences of anomalies and the associated consequential impact of faults, failures, and events per GNSS constellation, per geographical zone and per GNSS receiver type. Such information will allow analysis of what “trust” to place in GNSS and in doing so support the development of next generation GNSS applications.
The project was carried out in the frame of NAVISP Element 2, which is devoted to supporting competitiveness of European industries.
