A third civil frequency at 1176.45MHz will be added to the GPS system.
QZSS (Quasi Zenith Satellite System) proposed by Japan will also have the
new signal. This new frequency and the advent of QZSS will greatly enhance
the accuracy, reliability and robustness of civilian GPS receivers. One of these
enhancements is that it is possible to determine the GPS phase ambiguities
more or less instantaneously. This performance will have a tremendous impact
on navigation. In this paper, the possibility of precise positioning in the urban
area is examined from a point of instantaneous ambiguity resolution.
A typical QZSS constellation, …
