We used corrections (RTCM3.2-MSM) via NTRIP from a base five kilometers away, and in VRS mode from a regional network. The inverses and checks with established coordinates all came in under two centimeters in both horizontal and vertical. I took another 60 shots on the 150-meter course, and the horizontal came in at 11 millimeters (0.04 feet) 2 sigma. This is is typically what I have seen with other high-end rovers, including the one I bought along that day....
Under various canopy densities, the Oscar Ultimate performed as good if not better than nearly every rover I’ve tried, including other late-model multi-constellation rovers.Then some real fun: a “multipath hell” mark directly underneath a powerline tower. It is only the third of any rover I’ve tried that fixed in that spot. It hit the value I’d established (by conventional methods) within three centimeters 3D.
