Abstract
Currently, the real-time kinematic (RTK) method is common to be used in the global navigation satellite system (GNSS) positioning solutions, whereas it was primarily used for cadastral measurements, especially measurements of land parcels in Indonesia. In addition, the real-time precise point positioning (RTPPP) method is currently used extensively in Indonesia for positioning applications. Indonesia’s position located in the Asia-Pacific region makes it possible to observe a huge number of multi-GNSS satellite signals from GPS, GLONASS, Galileo, and Beidou which are very favorable for such measures. One particular problem in point positioning in Indonesia is that the measurements are often made in harsh environments covered by vegetation or buildings. This research is aimed at determining the quality of measurement data in static, RTK, and RTPPP methods in harsh environments and determining the contribution of multi-satellite constellations to the measurement of the three methods in harsh areas. Data acquisition of the methods was conducted in various locations covered by vegetation and building obstruction in the baseline distance scheme of 2.5 km, 5 km, 10 km, 20 km, and 50 km. In addition, an analysis of the level of accuracy and precision of static, RTK, and RTPPP measurement methods was conducted. In harsh environments, the accuracy and precision results of the static and RTK methods using multi-satellite constellations may provide solutions that meet the standards of land parcel measurement. Results obtained on a 50-km baseline are still good. However, the results of the baseline distance scheme show that the longer the baseline, the greater tendency for accuracy to decrease. The RTPPP method is not capable of generating data with a fixed solution for all satellite constellation schemes.
期刊介绍:
Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences.
The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
