Abstract :
An onboard navigation system is under investigation for mining machines. The system is intended for use in autonomous mining operations. The system provides heading information using a gyroscope, two flux-gate sensors, and clinometers. Testing has shown that the flux-gate sensors exhibit a static error when mounted on the mining machine. Recalibration of the sensor improved this situation. The gyroscope operated properly when mounted on the machine but required resetting with the flux-gate sensors or with data from the mobile control systems (MCS) every 14 min, due to inherent drifts.<>
