“…Trimble successfully developed real-time kinematic (RTK) technology, enabling instant updates of GPS data while in motion. Trimble real-time extended (RTX) technology facilitates real-time accurate positioning with centimeter-level precision in a quick convergence period [14]. Nowadays, GNSS systems are inexpensive; the RTK-GNSS single-frequency receiver costs only USD800 in the USA [15].…”

The development of unmanned agricultural tractors (UAT) represents a significant step towards intelligent agricultural equipment. UAT technology is expected to lighten the workload of laborers and enhance the accuracy and efficiency of mechanized operations. Through the investigation of 123 relevant studies in the literature published in recent years, this article reviews three aspects of autonomous navigation technologies for UATs: perception, path planning and tracking, and motion control. The advantages and deficiencies of these technologies in the context of UATs are clarified by analyzing technical principles and the status of current research. We conduct summaries and analyses of existing unmanned navigation solutions for different application scenarios in order to identify current bottleneck issues. Based on the analysis of the applicability of autonomous navigation technologies in UATs, it can be seen that fruitful research progress has been achieved. The review also summarizes the common problems seen in current UAT technologies. The application of research to the sharing and integrating of multi-source data for autonomous navigation has so far been relatively weak. There is an urgent need for high-precision and high-stability sensing equipment. The universality of path planning methods and the efficiency and precision of path tracking need to be improved, and it is also necessary to develop highly reliable electrical control modules to enhance motion control performance. Overall, advanced sensors, high-performance intelligent algorithms, and reliable electrical control hardware are key factors in promoting the development of UAT technology.

“…Another advanced method is Real-Time eXtended (RTX), a satellite-based correction service provided by various commercial providers. RTX corrections are computed by a network of reference stations that collect GNSS observations and send them to a centralized processing center [54]. The center calculates precise correction data and broadcasts it to users via geostationary satellites or internet connections.…”

Global Navigation Satellite Systems (GNSS) in precision agriculture (PA) represent a cornerstone for field mapping, machinery guidance, and variable rate technology. However, recent improvements in GNSS components (GPS, GLONASS, Galileo, and BeiDou) and novel remote sensing and computer processing-based solutions in PA have not been comprehensively analyzed in scientific reviews. Therefore, this study aims to explore novelties in GNSS components with an interest in PA based on the analysis of scientific papers indexed in the Web of Science Core Collection (WoSCC). The novel solutions in PA using GNSS were determined and ranked based on the citation topic micro criteria in the WoSCC. The most represented citation topics micro based on remote sensing were “NDVI”, “LiDAR”, “Harvesting robot”, and “Unmanned aerial vehicles” while the computer processing-based novelties included “Geostatistics”, “Precise point positioning”, “Simultaneous localization and mapping”, “Internet of things”, and “Deep learning”. Precise point positioning, simultaneous localization and mapping, and geostatistics were the topics that most directly relied on GNSS in 93.6%, 60.0%, and 44.7% of the studies indexed in the WoSCC, respectively. Meanwhile, harvesting robot research has grown rapidly in the past few years and includes several state-of-the-art sensors, which can be expected to improve further in the near future.

“…In Nowadays, GNSS technology and different positioning algorithms are used in order to monitor the surface waveforms before, during and after the earthquake and to determine the co-seismic displacements [14][15][16][17][18][19][20]. High-precision 3D position information from GNSS data plays an important role in detecting dynamic behavior on the fault [21].…”

The high pressure created by the stretching or compression of the rocks on the earth causes the earth's crust to break and faults occur. These faults are found in many parts of the world and are actively seen in Türkiye. In this study, space and satellite techniques and geodetic results of the Sofalaca-Şehitkamil Gaziantep earthquake that occurred on the Eastern Anatolian Fault Zone on 06.02.2023 in Türkiye were evaluated. Stations recording GNSS observations at 1Hz sampling interval of the network of Continuously Operating Reference Stations, Türkiye (CORS-TR) were used, homogeneously distributed in and around the epicenter where the earthquake occurred. In order to examine the characteristics of the surface movements occurring at the time of the earthquake, the Kinematic-PPP technique and the 1 second RINEX data in the RTKLIB software were evaluated with both real-time and post-process solution approaches. With both solution approaches, displacement amounts and velocities, of the surface waveforms occurring at the time of the earthquake were calculated at all stations. In addition, the co-seismic displacements of the selected 23 stations after the earthquake were calculated and the changes on the surface of the earthquake were interpreted. At GNSS Stations, the maximum velocities during the earthquake were calculated in the range of 1.6-23.3cm/s for the north component, 0.5-13.5cm/s for the east component, and 1.9-24.6cm/s for the up component. The post-earthquake co-seismic displacements at stations were determined as 0.1-37.1 cm for the north component, 0.1-22.7cm for the east component and 0.1-20.0cm for the up component.
