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.

The Evaluation of RTK method precision
 Horák, Aleš ; Volařík, Tomáš (referee) ; Kuruc, Michal (advisor)
The aim of this diploma thesis was to evaluate a precision of spatial position of chosen services from Czepos and TopNET providers. The chosen services were virtual reference station generated by MAC concept from Czepos provider and virtual reference station NVR3 from TopNET provider. Testing measurement was measured by RTK method with GNSS instrument from Leica System 1200. There were measured long-standing observations which lasts 24 hours and short observations which lasts five and twenty seconds. The short observations were measured at five points in area of Brno. Result of the thesis is comparisons of precisions in position and height.
