Practical Aspects of Real-Time Kinematic Measurements With Topcon Hiper+ And Trimble SPS855 Receivers in the CZEPOS And TOPNET Networks
Kostelecký, Jakub
The Real-Time Kinematic method is the most commonly used Global Navigation Satellite Systems (GNSS) method for positioning in geodetic practice. Within the framework of the article, the behavior of two GNSS devices Topcon HiPer+ and Trimble SPS855 during positioning by RTK method using corrections provided by networks of permanent stations CZEPOS and TopNet is assessed. Specifically, the use of 4 types of corrections from the CZEPOS network and 4 types of corrections from the TopNet network were evaluated. The behavior of the devices is assessed both according to the time required to perform the initial initialization and the time required to average the measurement result, and also according to the RMS (root mean square) error of the vertical component of the position. The evaluation found that the Trimble SPS855 fixed faster than the Topcon HiPer+ (3.6 minutes vs. 5.7 minutes). The averaging time is slightly shorter with the Topcon HiPer+ apparatus than with the Trimble SPS855 apparatus (30 seconds vs. 37 seconds), which is mainly related to the intuitiveness of the control software in the controller. Overall, it is stated that the Topcon HiPer+ equipment is more suitable for corrections from the TopNet network, and the Trimble SPS855 equipment works better with corrections from the CZEPOS network.

Accuracy analysis of current GNSS sensors
Jabůrek, Ondřej ; Sláma, Jiří (referee) ; Bureš, Jiří (advisor)
The purpose of this thesis is to test and analyze the accuracy of detemining the position and heights of contemporary GNSS receivers in RTK mode using the network of permanent stations CZEPOS with VRS3 - iMAX - MSM product. The test procedures are intended to provide representative results with potential use in conventional surveying applications. The goal of the thesis is to obtain measured data, analyze this data and evaluate the results. Based on this results we should be able to compare the tested devices. The comparison is intended to carry out an information that will help us to select a more suitable receiver for a particulat application in the common practice of surveyor.
