This paper reports on research that was aimed at gaining an understanding of what effect varying time intervals between the measurement of two points might have on accuracy and precision of a derived distance between those two points. A series of observations were taken with a time interval of both five minutes and 30 minutes, using both single base RTK and network RTK, and in both a clear environment and one experiencing substantial multipath. Observations at the ends of the ‘line’ were actually the same physical point, allowing ‘zero-length distances’ to be calculated and analysed. Results indicate that, when averaging data on points for one minute, regardless of receiver manufacturer, and regardless of whether multipath is present or not, a time interval of five minutes between measuring points at each end of a line produced more accurate results than a 30-minute time interval. These results are consistent with earlier research, but the qualification is that the five minute interval measurements may not be considered independent and it is left to the reader to make their own decisions on this point.
