Abstract

The uptake of Global Navigation Satellite System (GNSS) technology in a variety of industries has occurred at a rapid rate. In particular, the use of the Real Time Kinematic (RTK) differential technique has somewhat transformed the approach to many traditional tasks requiring accurate positional information. To maximise advantages provided by this technology, fixed base station antennas have become prevalent in areas where regular operation is anticipated. These fixed installations are often found on building rooftops or masts. Whilst many potential error sources exist in this form of surveying, it is critical that the position of the reference antenna is accurately known. This research addresses the positional stability of a reference antenna installed in a permanent application. The aim of the project was to develop methods to monitor a reference antenna for stability over a period of time. Several methods, including both terrestrial observations and GNSS observations, were adopted in the research. A comparative analysis revealed various characteristics of each method.The results of the research indicated that terrestrial observation, performed with a total station, was the most precise monitoring method of those undertaken. However, results that may be considered acceptable in a particular individual user’s situation were also obtained through the use of GNSS methods trialled. Limitations associated with the various methods were also discussed and would need to be considered for individual applications
