The article
“The Accuracy Potential of Galileo E5/E1 Pseudoranges for Surveying and
Mapping” has been published in the front page of ‘GPS World’ (March Edition).
The
article discusses the potential of the
new Galileo signals for pseudorange based surveying and mapping in
open areas under optimal reception
conditions (“open sky” scenarios) and suboptimal
ones (multipath created by moderate to thick “tree coverage”). The
article reviews the main features of the
Galileo E5 AltBOC and E1 CBOC signals; describes
the simulation strategy, models and
algorithms to generate
realistic E5 and E1
pseudoranges with and without
multipath sources; it also describes the ionosphere modeling
strategy, models and algorithms and
discusses and presents the
expected positioning accuracy and precision results.
According
to the simulations performed, pseudoranges can be
extracted from the Galileo E5 AltBOC signals with tracking errors
(1-σ level) ranging from 0.02 m (“open
sky” scenarios) to 0.08 m (“tree
covered” scenarios) whereas for the Galileo E1
CBOC signals the tracking errors range between
The research has been conduced within the Enhanced Code Galileo Receiver for Land Management in Brazil (ENCORE) project.
