The Virtual Reference Station (VRS) concept is revolutionising the work of surveyors
and other professionals who require positioning data. Accuracy levels in the centimetre
range that were made possible through real-time kinematic (RTK) GPS are now
achievable using the VRS mode of surveying. At present there is limited information
available on how well different GPS manufacturers receivers work using VRS. This
research provides an insight into the VRS performance capabilities of popular GPS
receivers on the market.
The past few years has seen many countries install permanent reference station networks
to spatially model the biases for a given region. The Department of Natural Resources
and Water (NRW) in South East Queensland has developed a network of permanent
reference stations called SunPOZ. SunPOZ operates using Trimble’s VRS software and
The aim of this research project was to evaluate the precision, accuracy, reliability and
performance of non-Trimble GPS receivers with regard to the SunPOZ VRS network.
Leica, Thales and Topcon GPS receivers have been utilized in the research.
The research results have confirmed that non-Trimble GPS receivers can operate within
the VRS network. The results indicate that the receivers assessed are reliable, and
produce similar precision levels and initialisation times to previous testing. The receivers
performed well within the network of reference stations and provided results that should
give greater confidence in the use of the VRS technique for precise point positioning.
