| Summary: | The extra-terrestrial method commonly used by land parcel surveyors is the static
method and the Real-Time Kinematic (RTK) method that utilizes the Global
Navigation Satellite System (GNSS) technology. Indonesia is located in the Asia
Pacific region where the availability of GNSS satellites such as GPS, Glonass, Galileo,
and Beidou strongly support the measurements. Measurements are usually done in a
closed area with vegetation and building obstruction. The purpose of this study was to
determine the data quality of static, RTK, and Real-Time Precise Point Positioning
(RTPPP) measurement methods in closed areas and also to know the contribution of
multi-satellite constellations for static, RTK, and RTPPP methods in closed areas.
Data acquisition was carried out in various locations with high-density vegetation and
building coverage in five baseline distances, i.e. 2.5 km, 5 km, 10 km, 20 km, and 50
km. Data quality assessment obtained from the value of Dilution Of Precision (DOP),
multipath, Signal to Noise Ratio (SNR) and sky plot of observation data. The static
method is processed with Leica Geo Office (LGO) software to determine the level of
precision and accuracy of each combination of satellite constellations. Also for the
data obtained using the RTK and RTPPP methods, the level of precision and accuracy
will be analyzed. In closed areas, the use of multi-satellite constellations is the best
solution to obtain data quality with an optimum level of accuracy and precision for
both static and RTK methods. The use of GPS satellite constellation is not feasible
because satellite geometry obtained in closed areas is insufficient. The RTPPP method
cannot provide a good solution, all obtained data have a single solution.
