Positioning with low-cost GNSS (Global Navigation Satellite System) receivers is becoming increasingly popular in many engineering applications. In particular, dual-frequency receivers, which receive signals of all available satellite systems, offer great possibilities. The main objective of this research was to evaluate the accuracy of a position determination using low-cost receivers in different terrain conditions. The u-blox ZED-F9P receiver was used for testing, with the satellite signal supplied by both a dedicated u-blox ANN-MB-00 low-cost patch antenna and the Leica AS10 high-precision geodetic one. A professional Leica GS18T geodetic receiver was used to acquire reference satellite data. In addition, on the prepared test base, observations were made using the Leica MS50 precise total station, which provided higher accuracy and stability of measurement than satellite positioning. As a result, it was concluded that the ZED-F9P receiver equipped with a patch antenna is only suitable for precision measurements in conditions with high availability of open sky. However, the configuration of this receiver with a geodetic-grade antenna significantly improves the quality of results, beating even professional geodetic equipment. In most cases of the partially obscured horizon, a high precision positioning was obtained, making the ZED-F9P a valuable alternative to the high-end geodetic receivers in many applications.

“…Displacement monitoring is important part of safety management in many contexts, e.g., hillside surface displacement, along with landslide risks, due to large civil works above ground such as motorways, fly-over bridges, wind generators or water reservoir dams; or below ground such as mines; urban land subsidence, foundation movement or deformation in high-rise buildings, bridges and so forth. For precision engineering measurement of 3D displacement, in recent times, GNSS-based sensor units are being employed, which use e.g., BeiDou [17], Global Positioning System (GPS) [18], GLONASS [19], or Galileo [20] satellite constellations. All, in theory, are capable of millimetre-level 3D positioning or movement accuracy.…”

This paper presents the horizontal approach for the development of Internet of Things (IoT) platforms, based on a generic, multi-service, cloud-based IoT operational platform, called EMULSION, elaborated for the rapid development of mobile IoT systems and quick roll-out of corresponding IoT services. The platform is successfully used as a basis for the development of various IoT prototype systems for different IoT domains, such as smart environment control, smart health, smart electric appliances, smart water supply, etc. As an example of these, a ground surface displacement monitoring IoT system, operating in the area of smart environment control, is presented, along with aspects of the hardware design of the produced low-cost, small-size, global navigation satellite system (GNSS)-based sensor unit, utilized by it. The system architecture design is set out, supplemented by the presentation of initial test results.

“…Yerel CORS ağı verileri deformasyon analizi ve yapı sağlığı izleme çalışmalarında kullanılmıştır (Akpınar, Aykut, Dindar, Gürkan, & Gülal, 2017;Gümüş & Selbesoğlu, 2019). Yerel CORS ağı kullanılarak baz mesafesinin doğruluk, presizyon ve tamsayı belirsizlik çözüm oranı üzerindeki etkisi araştırılmış ve GNSS ölçmelerinde baz mesafesi ile ölçmelere ait varyans değeri arasında matematiksel bir model oluşturulmuştur (Gökdaş & Özlüdemir, 2020a).…”
