Abstract
A system including a mobile machine and a central control station is provided. The mobile machine includes a communication device and a position monitoring system including a receiver configured to receive position data from a positioning satellite and generate a position signal. The position monitoring system also includes an inertial navigation unit including a sensor configured to measure a parameter of the mobile machine and generate a movement signal. The position monitoring system also includes a controller configured to receive the position signal and the movement signal, detect an unavailability of the position signal, calculate a position parameter, determine whether a difference between a first and a second value of a parameter exceeds a predetermined threshold, and generate a warning signal. The central control station is configured to communicate with the controller, receive the position signal and/or the movement signal, and monitor the position of the mobile machine.
