Since the last decade the integer phase ambiguity resolution has become one of
the most important elements in the GPS field because of its impact on the
accuracy. Several scientific researches have been carried out for resolving the
integer ambiguity. One example of such kind of researches is the Quick GPS
ambiguity resolution for a short baseline (KTH method). The study focus on
investigation of the impact of the selected elements: the GPS signal, the
observations elevation angles and the GPS satellites azimuth on the KTH
method performance for resolving the integer phase ambiguity.
The investigation has covered carrier phase measurements for three baselines
with length less than one km for each and “GeoGenius” software package as
the quality control for the fixed ambiguities of the KTH method results. The
KTH method achieved more than 84 percent of success in the level of signal
strength 8; about 90 percent for elevation angel between (55 65)° and
approximately 94 percent for GPS satellite azimuth in range of (130 150)°.
The overall results showed a clear correlation of about 0.9 for most of the cases
between KTH method and the selected components. In such a case it leads to
a high performance of the method under healthy reliable observations
conditions, and the method has the capability to yield outcomes expected to be
within a specific accuracy by knowing the level of group elements (signal
strength, elevation angle and satellite azimuth) that have been used.
