Determining the Form of Error Distribution of Geodetic Measuring

“…The circuit for transmission and processing of the measuring signal is shown in Figure 1. The measured value by its size is a random value of the error of its measurement is also random (when eliminating the systematic component of the error; the study of systematic errors is considered, for example, in Tereshchuk et al, 2019). The random state of the object of measurement and its errors leads to some uncertainty, but before the measurements it is known that the value measured is within certain limits, and its value must be obtained with some degree of accuracy, the preliminary information about the size of the object reduces uncertainty and the expected error will show the limits of this uncertainty, i.e.…”

Acceptance Tests of the Software and Technical Complex of the High-Precision Satellite Positioning System in the Kacharsky Mine

“…Institute of space technique and technology, Almaty, Kazakhstan; 3 KTH Royal Institute of Technology, Stockholm, Sweden. E-mail: a.baltiyeva@gmail.com, raskaliyev@mail.ru, shamls@mail.ru, huaan.fan@abe.kth.se, gylxana@mail.ru…”

“…The reason for the discrepancy was the definition and assignment of coordinates of the base "basa kachar" and BSDC in different coordinate systems. The coordinates "basa kachar" were determined in the LCS of the Kacharsky open-pit mine, while the coordinates of the BSDC, according to the previously made draft and technical design, were determined in the international coordinate system ITRF-2014 [3,4].…”

Particularly, it was decided to determine and set the coordinates of the phase center of the GNSS antenna of the BSDC using the differential correction operation relative to the base station "basa kachar".…”

Accuracy of Coordinate Determinations of the Network of Protected Zone Points According to the Results of GNSS Observations

“…A number of works are also devoted to the processing of the obtained results of GNSS observations. For example, the paper (Tereshchuk et al, 2019) considers the processing of the results of field satellite GNSS measurements at the points of the State Geodetic Network of the Northern Region of Ukraine using OCTAVA and Graf-Nav/GrafNat software packages. Based on the results of the study, a method has been developed for estimating the accuracy of processing the results of GNSS observations by software packages based on the method of double nonequilibrium measurements.…”
