Abstract:	An on-the-fly (OTF) positioning algorithm is used in a postprocessing mode to determine precisely the vector between two antennas. The algorithm is used in both a standard differential form, between a static and a moving antenna, and a modified relative form, between two moving antennas. The results of two tests that demonstrate this capability are presented. The first test used a turntable with an antenna in motion with respect to a fixed reference site. Independent truth data were obtained by a static survey of the instrument. In the second test, the antennas were mounted on car roofs. The two vehicles performed drive-by’s that were documented by a video camera mounted on one of the cars. The video frames were time-tagged with GPS, and the distance between vehicles was obtained by measurements of a scale attached to the second vehicle and visible in each video frame at the closest approach. Analysis of the data with fixed and moving reference sites is presented.
