Effect of time interval variations on network RTK in a high multipath environment

The research aim for this project was to investigate the effect of time interval variations on Network RTK in a high multipath environment. Meaning does the time in between observing each point at the end of a line using Network RTK GNSS effect the accuracy of the calculated distance between the two points. And how is the relationship of time and accuracy affected when introduced to a high multipath environment. Finally, how can these determined accuracies for horizontal distance measurement be applied to survey regulation accuracy for cadastral surveys of 10mm + 50ppm stated in the CSR. The analysis looked at two different datasets. First a dataset captured over a 12-hour period free from the effects of multipath. And secondly a dataset captured over a 12- hour period with the effect of multipath present. The analysis calculations used the Zero Distance Method and utilized two different time intervals firstly a 30-minute window and second a 5-minute window. The key findings from the research found that using the shorter time lapse window of 5-minutes produced a calculated distance with high accuracy over the 30-minute time lapse window. The was found for both the multipath free and multipath present datasets. These results successfully achieved the research aim and aligned with previous research.
