Abstract [en]

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.
