Abstract
Integrated systems for kinematic positioning have been studied extensively from the perspective of the navigation problem. A model is presented for an integrated system that places greater emphasis on the geodetic problem. The model integrates global positioning system (GPS) carrier phase measurements with dead-reckoning (DR) sensor measurements from an odometer and three fibre-optic rate gyroscopes. Mathematical models are developed for a modified form of the triple-difference carrier-phase observable, odometer distance measurements and a transformation from vehicle axis rotations to changes in orientation in the World Geodetic System 1984 (WGS84) coordinate system using a quaternion representation of rotations. Results from field tests show that the integration model achieves improved positioning performance during periods of limited satellite visibility (fewer than four satellites) over that provided by the dead-reckoned solution alone.
