Attaining Required Positioning Accuracy in Archeo-Geophysical Surveying by GPS

Abstract

Tests of various types of inexpensive global positioning system (GPS) receivers were performed in order to asses the utility of the technique for archeo-geophysical surveying. It is demonstrated that under favorable conditions a 30 cm relative uncertainty of the kinematical positioning is achievable and that under conditions, where a degradation of the GPS fixes occurs during the scans, it is possible to compensate for the errors, and refine the results by post-processing of the measurement data
