Precise determination of GPS phase ambiguity integers on the fly is a key requirement for accurate kinematic positioning. A fully automatic approach is developed to resolve phase integers and perform airborne GPS positioning for aerial triangulation using dual-frequency GPS data. Although always helpful, static initialization is not required; the problem of signal interruptions (losses of lock) while an airplane is maneuvering distant from a base station has also been addressed. Test results show that positions using precise phase data are reliably determined with this approach.
