Overview

The NovAtel RAIM (Receiver Autonomous Integrity Monitoring) firmware utilizes FDE (Fault Detection and Exclusion) which detects and eliminates flawed signals that may affect the positioning information by having redundant pseudorange measurements. It then recalculates the positioning information with the corrected signals to improve the accuracy of the results. It also allows uninterrupted operation in case of a failure in the GNSS receiver.

The RAIM algorithm was designed for aviation navigation systems that require precise positioning information during different stages of flight. However, users can modify the parameters to create a customized solution that meets their requirements.

Features

  • Fault Detection and Exclusion
  • Designed for aviation navigation systems
  • Customizable parameters to meet user requirements
  • Enhanced accuracy of positioning information
  • Allow uninterrupted operation during GNSS failure
  • Alert users when RAIM is unavailable

Enhance Positioning Solution

When satellites experience pseudorange measurement errors that typically cause significant positioning error, RAIM can be used to enhance the positioning solution. The RAIM algorithm is able to detect the pseudorange anomaly and eliminate it from the position solution. The receiver is then able to recalculate the position with the bad pseudorange removed and produce a position with far less error.

Customized Performance

While used primarily for aviation navigation systems requiring signal and position integrity during various stages of flight, RAIM parameters can be customized to meet the requirements of a range of applications requiring continuous operational confirmation.
