Abstract

This paper reports an investigation into the horizontal accuracy of various static GNSS logging durations from two to 24 hours, at five sites with sky obstructions from 0% to 90%, using two online GNSS processing systems. It was found that in almost all situations, 12 hours of data would provide reliable results, and no appreciable difference was found between AUSPOS and Trimble RTX. Further refinement of the outcomes are presented in the form of a graph of suggested logging durations versus percentage of sky obstructions. These may be useful to the surveying profession, provided they are used as suggestions only and further redundancies are built into surveys based on normal good practice and relevant control survey requirements.
