520 _aPresents an economic positioning system for decimetre level accuracy mapping with emphasis on producing base maps for GIS applications. Investigates the main issues in system utilisation including treatment of system errors, phase measurements ambiguity resolution, the impact of receiver dynamics on system performance and the required occupation timer per point.
