A bit blown away yesterday at the performance of the Javad system.
I was using the RTK setup w/ the LS, the T2 base and a 1W radio--and facing locating a wetland edge in dense woods. I'd gone out the day before and flagged the wetlands, but up here in Massachusetts we're close to full leaf-out and I was expecting a slow go of locating all the points. Trees are densely packed and 60-80 feet tall.
I was fortunate in being able to set the base and radio in a large open meadow beside the woods--about as good as it gets. But I was still leery of what would happen when I slogged into the oaks and maples and began to work..
Instead of long waits to collect points, the LS simply rocked. I collected 134 points, each separated by an average of about 35 feet, in 2.5 hours. That's 54 points an hour, which included walking from point to point. To put this in context, my firm has done this sort of location for a couple decades using total stations. On a good day's field work, a crew would survey 40-50 points, on a spectacular day perhaps 60+. The job I completed yesterday was normally a 2-3 day event. So I saved a couple days work, and got far more precise locations.
As an aside, the farthest distances from the base/radio were about 500 feet, so I wasn't pushing the radio's range. Perhaps performance would have dropped if I were farther out. Also, even in the densest woods the LS was pulling in 10-11 satellites. All in all, noteworthy!
