GPS Observables and Error Sources for Kinematic Positioninglability, atmospheric, and measuring errors are quantified. In particular, the effect of multipath on code observations is discussed and its impact on the related use of code measurements to estimate the carrier phase ambiguities is analysed. The estimation of C/A code noise under field conditions i

Design for an Airborne GPS-Inertial Surveyord accuracies of 60 cm horizontal and 15 cm vertical in terrain profiling. APTS used a high accuracy inertial navigation system periodically updated by measurements from a laser tracker, which used surveyed retroreflectors located on the ground. A laser profiler fixed to the IMU measured distance to
