“…The slope greater than 40% and the checkpoints located in the model's border resulted in low precision due to the interpolation methods during the photogrammetric reconstruction. Besides that, the fast static GNSS survey method may exhibit signal failure due to relief obstruction and its position is influenced by multipath (Pirti, Yucel, & Gumus, 2013). Also, a joint analysis of the horizontal discrepancy (E-N) was performed making the correlation analysis more solid to the altitude discrepancies concerning E and N than a separate evaluation (Atkinson, 2005), although the independent components were also measured as a number of works also present this components separately and is easier to compare.…”

Geometric accuracy is an important attribute of cartographic products and UAV photogrammetry has been gaining market in topographic mapping thanks to high spatial and temporal resolution, however, they need proper evaluation following accuracy standards and protocols. Regarding this, this work evaluates products from digital photogrammetry from images acquired with a fixed-wing UAV (18Mpixel camera) in a 300-380m height flight over a Hydroelectric Power Plant (HPP) in Brazil. A dataset of 23 ground control points assessed with an RTK-GNSS (using natural targets) was validated with its homologous in the Digital Surface Model (DSM) and the orthomosaic, following a workflow in which the appropriate statistics were applied. Following parametric tests like the Students t-test and the Chi-square, we compared the results with the Brazilian Cartographic Standard for digital cartography, achieving minimum scale of 1: 20,000 (RMSE of 1.04 m) for the orthomosaic, and minimum scale of 1: 10,000 (RMSE of 1.31 m) for the elevation in the DSM, although, no special targets were used. As the 3D mapping generated using the photogrammetry still needs a protocol to evaluate the accuracy, this work applied a proposed workflow respecting the quality of the data to meet the requirements of the cartographic standard.

“…In particular, the authors made a comparison of the designated coordinates of the Cessna 172 in the GLONASS system to the solution in the GPS navigation system for the same research method. The In another accuracy test, the authors determined the shift vector of coordinates in the 3D space, between the GPS and GLONASS solutions, in the form of the 3D-error parameter, as below [19][20]:…”

The article presents the possibility of using the Between Satellite Single Difference method (BSSD) in the precise determination of the aircraft position in the Global Navigation Satellite System GLONASS navigation system. The paper presents the mathematical model of the BSSD method, describes the research test and presents the results of conducted examinations. The research test was conducted within the implementation of the GLONASS satellite technique in air navigation. The test research uses the actual GLONASS navigation data registered by the Topcon HiperPro receiver, mounted onboard a Cessna 172 aircraft. Obtained findings of the research work are interesting from the perspective of implementation of the GLONASS satellite technique in aviation. It should be emphasized that standard deviations of the determined position of the Cessna 172, using the BSSD method, do not exceed 2m. The article also determines the accuracy of a position of the Cessna 172 in the GLONASS solution with reference to a solution in the GPS navigation system.

“…All the solutions proposed by the aforementioned authors are closely related to other studies concerning, generally speaking, satellite measurements. They refer, for example, to the combined use of different satellite systems for the measurements in the RTN GNSS mode (Gunter, 2000;Pirti et al, 2013;Xingxing et al, 2015), to the development of reference station network in Poland (Wajda et al, 2008;Figurski et al, 2011), or to the application of various technical solutions for GNSS receivers.…”
