Abstract
In the middle of 2011 Trimble introduced the CenterPoint Real time extended (RTX) real-time positioning service providing centimetre accurate positions for real-time applications. This emerging technology means that a GNSS system can be used without reliance on an internet connection, and independent from a conventional base/rover set up, thus overcoming the limitations of the existing systems.
A comprehensive literature search reveals a lack of testing in the Sothern Hemisphere to date. This new solution needs to be tested for accuracies and precisions that can be achieved by comparing against a conventional network RTK (NRTK) system and determine if there is any significant decrease in accuracy or precision over time.
The tests were conducted on a high accuracy survey permanent mark which has known coordinate values. The testing included the data collection from both systems (RTX and NRTK) on the survey mark individually. Coordinates from each system were compared against the known coordinates to assess accuracy and precision.
RTX failed to meet the meet the accuracies or precisions as stated in the manufacturers datasheets but the system’s precisions did increase over time.
The benefit of this dissertation is to produce a reliable and current set of results in the Sothern Hemisphere and to assist the survey profession in understanding this new emerging technology.
