We tried the upsampling with the LS as a network rover and were shocked at the upgrade in performance. We have a free and powerful RTN in New York, but who operates at 1 Hz anymore. Having this 5 Hz option at hand as we reach the ends of our radio range will change our methods for sure.
Bigger for us though is the upsampling of our UHF. We often run two or three rovers from a base, but at the 5 Hz that the LS demands now, our 2008 vintage Triumph-1 rovers are usable but pretty flaky. In the conditions where the Tri-1s would have stay fixed for hours, at 5 Hz broadcast they go autonomous as soon as the rover moves. Once we stop, they slowly cycle autonomous to fixed with 7 or 8 sats to fixed with 10+ sats. The positions stored then are almost always good.
This morning, though, I copied our 5Hz profile to a 1-5Hz profile, only toggling on the upsample. I set up a Triumph 1 base using SurvCE just to test, broadcasting at 1 Hz of course. Walked over to the LS and it was already fixed with 6 engines. Stayed fixed against the building and fixed quickly under the trees at 5 Hz upsampled. A Triumph1 rover also fixed and stayed fixed the whole time, like old times.
So, a question we have is theoretically how much performance are we sacrificing by upsampling 1 Hz vs. broadcasting 5Hz?
You know, just as you get confident that you have mastered and implemented the state of the art of RTK, Javad quietly re-states the art. I couldn't be more happy with this equipment.
