Abstract

The kinematic survey with GNSS measurements has become very important because of the recent Italian laws about road cadastre. The Laboratory of surveying of Perugia University has deepened the aspect of the road axis survey with GNSS measurements. The analysis has began with a kinematic survey with GNSS measurements at a sampling rate of maximum 20 Hz. This survey has been made with three GNSS static receivers beside the surveyed road and one antenna on a vehicle. All the redundant results (for each epoch it was possible to have three results of each parameter: position, DOP…) has been checked and statistically filtered with semi-automatic procedures. In the next step it has been installed on a van also an inertial and GPS measurement system, that it is able to receive OMNISTAR-HP corrections. It was possible to compare the solutions about kinematic parameters from the IMU-GPS system with the same kind made by GNSS measurements. Now it is being carried out the data about the orientation of the van by means of four GNSS antennas together with the measurements deriving from the IMU-GPS system.
