“…In areas with dense vegetation, as shown in Figure 2, we observed issues related to multipath and cycle slip, as noted by Li et al (2019). Another study by Janos et al (2022) demonstrated that Low-cost GNSS receivers can even outperform in certain situations. GNSS receivers prove valuable in signal-prone areas such as landslide-prone forests, mining areas with structures, bridges, dams, and other engineering constructs.…”

The expanding population in Surabaya, Indonesia, motivates the local water supply entity, Surya Sembada Surabaya's Local Water Supply Utility, to uphold the expected level of service concerning asset management. PDAM already employs a smartphone-based Global Navigation System (GNSS) for recording meter positions and water usage to manage their asset inventory, albeit with suboptimal position accuracy. The utilization of Geodetic GNSS is seen as less effective due to its considerable size and associated high expenses.

“…In order to obtain high-resolution position information of the GPR data, an integrated GPR and GNSS system was applied to collect the GPR data and their geographical coordinates [ 49 , 50 , 51 , 52 , 53 ]. As shown in Figure 4 , this system mainly includes the GPR control unit, the transmitting antenna, the receiving antenna, the survey wheel, the GNSS base station, and the GNSS mobile station.…”

Integrated TLS and GPR data can provide multisensor and multiscale spatial data for the comprehensive identification and analysis of surficial and subsurface information, but a reliable systematic methodology associated with data integration of TLS and GPR is still scarce. The aim of this research is to develop a methodology for the data integration of TLS and GPR for detailed, three-dimensional (3D) virtual reconstruction. GPR data and high-precision geographical coordinates at the centimeter level were simultaneously gathered using the GPR system and the Global Navigation Satellite System (GNSS) signal receiver. A time synchronization algorithm was proposed to combine each trace of the GPR data with its position information. In view of the improved propagation model of electromagnetic waves, the GPR data were transformed into dense point clouds in the geodetic coordinate system. Finally, the TLS-based and GPR-derived point clouds were merged into a single point cloud dataset using coordinate transformation. In addition, TLS and GPR (250 MHz and 500 MHz antenna) surveys were conducted in the Litang fault to assess the feasibility and overall accuracy of the proposed methodology. The 3D realistic surface and subsurface geometry of the fault scarp were displayed using the integration data of TLS and GPR. A total of 40 common points between the TLS-based and GPR-derived point clouds were implemented to assess the data fusion accuracy. The difference values in the x and y directions were relatively stable within 2 cm, while the difference values in the z direction had an abrupt fluctuation and the maximum values could be up to 5 cm. The standard deviations (STD) of the common points between the TLS-based and GPR-derived point clouds were 0.9 cm, 0.8 cm, and 2.9 cm. Based on the difference values and the STD in the x, y, and z directions, the field experimental results demonstrate that the GPR-derived point clouds exhibit good consistency with the TLS-based point clouds. Furthermore, this study offers a good future prospect for the integration method of TLS and GPR for comprehensive interpretation and analysis of the surficial and subsurface information in many fields, such as archaeology, urban infrastructure detection, geological investigation, and other fields.

Although Real-time kinematic (RTK) is a positioning technique with high accuracy at the centimeter level, the investment cost for this positioning technique is relatively high. To reduce the investment cost, low-cost, dual-frequency, multi-Global Navigation Satellite System (GNSS) receivers can be considered. In Vietnam, the Continuously Operating Reference Stations (CORS) network has operated and covered the whole country. Therefore, the combination of low-cost, dual-frequency, multi-GNSS receivers and the CORS network can make RTK positioning easier and less expensive. The aim of this study is to evaluate the potential of applying the RTK positioning technique using a low-cost, dual-frequency, multi-GNSS receiver and the CORS network in Vietnam. In this study, four positioning experiments were performed in static and kinematic modes, and at near and far locations in which the rover was about 3 km and 30 km from the CORS station, respectively. Experiments conducted near the CORS station gave good results with the average standard deviation of 0.2 cm for static positioning and average deviation of 2.2 cm for kinematic positioning, and the FIX rate of greater than 95%. Therefore, the experimental results show the excellent potential of RTK positioning using low-cost, dual-frequency, multi-constellation receivers with the CORS network in Vietnam.
