Utilization of low-cost GNSS RTK receiver for accurate GIS mapping in urban environment

Original language description

The main objective of the work was to evaluate positioning performance of low-cost GNSS receiver u-blox ZED-F9P with patch antenna in GIS mapping scenarios. The whole mapping kit consisted of the mentioned receiver, a smartphone and two mobile applications. Thirty testing points with different levels of sky view were temporarily set up in an urban environment. Real-Time Kinematic (RTK) technique was used to estimate their position with the mentioned low-cost receiver and geodetic grade Trimble R10 receiver. Coordinates obtained from two independent measurement campaigns were compared to reference positions computed by rapid static relative technique. Both receivers provided a similar level of positioning correctness except two testing points where the geodetic grade GNSS receiver showed large errors in the first campaign. With an exclusion of these two points, both receivers delivered mean horizontal distances from the reference positions slightly exceeding 0.04 m and standard deviations oscillating around 0.05 m. In case of height estimates, mean differences from the reference values were at the level of 0.02 m for the Trimble R10 receiver and 0.07 m for the u-blox receiver, with standard deviations around 0.08 m reached by both tested devices. Secondly, areas of four polygons in the same urban environment were measured. Relative differences from reference values of areas ranged from 0.01 % to 0.46 %, with the Trimble receiver being slightly better in this task.
