The Design of Ultra-High Integrity Navigation System for Large Autonomous Vehicles

This paper describes the design of a high integrity navigation system for use in large autonomous mobile vehicles. A frequency domain model of sensor contributions to navigation system performance is used to study the performance of a conventional navigation loop. On the basis of this, a new navigation system structure is introduced which is capable of detecting faults in any combination of navigation sensors. An example implementation of these principles is described which employs a twin GPS/IMU MMW radar/encoder navigation loop.
