NovAtel RAIM (Receiver Autonomous Integrity Monitoring) is a GNSS receiver firmware solution designed to ensure continuous and reliable positioning by autonomously detecting and excluding faulty satellite signals. RAIM uses redundant pseudorange measurements to identify anomalies and recalculates the position solution to maintain accuracy and integrity. Originally developed for aviation navigation systems, RAIM is customizable for a wide range of applications requiring uninterrupted GNSS performance.
Features
- RTCA DO-229D Based: Implements standards from the 2006 RTCA DO-229D specification.
- Fault Detection and Exclusion (FDE): Uses redundant pseudorange measurements to detect and exclude faulty GNSS signals.
- User Alerts: Notifies users when RAIM is unavailable or compromised.
- Customizable Parameters: Adaptable to various operational requirements beyond aviation.
- Continuous Operation: Maintains positioning even during GNSS signal failures.
Benefits
- Improved Position Accuracy: Eliminates erroneous pseudorange data to reduce positioning errors.
- Enhanced GNSS Integrity: Ensures reliable signal performance for critical applications.
- Operational Continuity: Supports uninterrupted GNSS-based operations in dynamic environments.
- Versatile Application: Suitable for aviation, transport, and other sectors requiring high-integrity navigation.
- User Confidence: Provides alerts and autonomous corrections to maintain trust in GNSS data.
