Abstract
The Network Real-Time Kinematic (NRTK) GPS and GNSS technology is
increasingly being utilised for a wide range of surveying and mapping
applications, providing users with instant and highly accurate position
information over distances of several tens of kilometres. This paper reviews
the principles behind the two prevalent NRTK methodologies currently
available, the Virtual Reference Station (VRS) approach and the Master-
Auxiliary Concept (MAC). The inherent differences are outlined, and the
two concepts are compared from both the user’s and the network operator’s
perspective. While both methods are supported by the major GNSS
equipment manufacturers and deliver positioning results at the same
accuracy-level, there are significant differences in regards to the distribution
of processing load, correction data transparency, legal traceability and
required bandwidth. Several CORSnet-NSW sites are used to empirically
determine the average bandwidth required for NRTK operation under typical
conditions based on differently sized networks ranging from 3 to 9 reference
stations. While the bandwidth required for MAC is significantly larger than
for VRS, particularly for large cells, results show that it can be readily
supported by common radios.
