Abstract
The Global Positioning System (GPS) can be utilised in a
wide range of deformation monitoring applications. During
the past few years a methodology has been developed for
processing data collected by GPS networks consisting of a
mixed set of single-frequency and dual-frequency receivers.
The strategy is to deploy a few permanent GPS stations
with dual-frequency, geodetic-grade receivers surrounding
an ‘inner’ network of low-cost, single-frequency GPS
receivers. The dual-frequency GPS network is used to
generate a file of ‘corrections’, analogous to Wide Area
DGPS correction models for the distance dependent biases.
These ‘corrections’ are then applied to the doubledifferenced
phase observations from the inner receivers to
improve baseline accuracy (primarily through empirical
modelling of the residual atmospheric biases that otherwise
would be neglected). The performance of this configuration
has been investigated by simulating such a two-stage GPS
network using data collected in different geographical
regions.
