Simple autonomous control of wheeled vehicles with limited operation amount using high-precision satellite positioning technology

The world development of science and technology prompts many countries to use their own modern coordinate systems, determined on the basis of satellite measurements. Moreover, the modern system must be characterized by its openness and unity for the entire territory of the country. One of the main problems arising during the creation and operation of our own high-precision positioning satellite systems in the Republic of Kazakhstan are: the lack of domestic satellite equipment, specialized software and test methods for the software and hardware complex. A unique opportunity appeared in the development and testing of the software and hardware complex of the high-precision satellite positioning system at the Kacharsky open pit thanks to the funding of the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan through grants for scientific and technical projects for 2018–2020 (grant No. AP05136083) and co-financing of the private partner JSC «SSGPO». The article presents the results of technical solutions for the implementation of a high-precision satellite positioning system, in particular, the creation of a permanent base station (BS) of global navigation satellite systems (GNSS) at operating open pit. The primary purpose of the work is to provide high-precision positioning of an open field in order to determine geodetic coordinates using modern satellite navigation technologies in real-time and post-processing. This development continues the path of introducing the elements of Industry 4.0, which is currently being carried out at the Kacharsky open pit.

Global Navigation Satellite

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.

Mine Surveying

The article presents technical solutions for the implementation of a high-precision satellite positioning system when performing mine surveying in an open pit. A system was put into commercial operation at one of the fields of JSC "Sokolovsko-Sarbayskoe mining and processing production association" (JSC "SSGPO") this year. The project was funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan through grants for scientific and technical projects 2018–2020 and was co-financed by a private partner, JSC "SSGPO". All work was carried out jointly with the Subsidiary Limited Liability Company "Institute of Space Engineering and Technology". The technology of differential correction of GNSS signals in the form of base stations of differential correction (BSDC) allows solving the problems of high-precision satellite positioning. The main task assigned to the continuously operating base station is the collection of code and phase data from GPS/GLONASS satellites and the distribution of this data to users (services of JSC "SSGPO" and specialists of contracting organizations performing mine surveying and geodetic work at the field). Development of a mobile module and the rationale for its inclusion in the BSDC is provided in this work.
