20090099772 | Augmented navigation system and method of a moving object - In an augmented navigation method of a moving object, an error model capable of outputting calibrated data is created according to global positioning system (GPS) data and inertial detecting data when an object is moving. When the moving object enters an invisible region, the calibrated data and the inertial detecting data are combined together to generate an estimated position. In order to achieve the method, an augmented navigation system is provided. The augmented navigation system includes a front platform for receiving the GPS data and generating the inertial detecting data. The GPS data and the inertial detecting data may be transmitted to a rear platform through a wireless network. The error model is disposed on the front platform or the rear platform, and the rear platform has an estimator capable of combining the calibrated data outputted from the error model with the inertial detecting data to generate the estimated position. | 04-16-2009 |
