NAVIGATION SYSTEM AND METHOD FOR TRACKING THE POSITION OF AN OBJECT |
摘要 |
A navigation system for tracking the position of an object includes a GPS receiver (28) responsive to GPS signals for periodically providing navigation state measurement updates (162) to a navigator update unit (29). The system also includes a dead-reekoning sensor (98) responsive to movement of the object for providing movement measurements (164) to a sensor update unit (61). The sensor update unit (61) receives movement measurements (164) provided by the dead-reckoning sensor (98) and the navigation measurements (16) from the navigation update unit (29). The position change measurements (165) provided by the sensor update unit (61) and the dead-reckoning measurements of the navigation update unit (29) are utilized by a navigations propagation unit (110) to calculate a new or modified dead reckoning measurement.
