Abstract
Distance dependent errors limit the accuracy of high
precision real-time DPGS applications to 1 to 10 ppm.
The objective of this investigation is to improve the
reliability and speed of On-The-Way (OTW) ambiguity
resolution and to enhance the accuracy of the GPS
solution by using data from multiple reference stations.
Extensive test measurements carried out in the northern
part of Germany using the real-time processing
software package GNRT with only one reference station
clearly show distant dependent errors of about 1
ppm and more. The postprocessing simulation of a
reference station network reduces the effects to
generally less than 1 cm without any distance dependencies.
