GNSS-RTK Precise Positioning for Engineering Applications
 Grečnár, Jiří ; Talácko,, Milan (referee) ; Bureš, Jiří (advisor)
The thesis deals with precision analysis, process optimization and repeatibility of GNSS-RTK measurements for surveying aplication. Measuring procedure, that enables determination of a spatial position with a permissible deviation less than 10mm, was tested based on previous published findings. The test procedure was tested on two sets of test measurements obtained during 27 h and 26 h observations in connection with CZEPOS. The results were later analyzed. The first set of measurements was measured by the RTK3-GG method (9 m and 60 km vectors) and computed by a network solution VRS3-MAX-GG. Both were in ideal conditions – ideal, not obstructed observational horizon and good availability of differential corrections. The second set was measured by RTK3-GG method (22 km and 62 km vectors) and computed by network solution VRS3-MAX-GG. Both were in adverse conditions - obstructed observational horizon and adverse availability of differential corrections. Precision analysis and design of appropriate filtering method and optimal measurement procedure were done based on the results obtained from the test measurements. Optimal measurement procedure was then tested by measurements in a three point network.
