Thx, will try them out, likely over the weekend.
Testing went fairly well. We flew the 550 drone I built and got RTK Float (carrier phase ambiguity not resolved) easily, but again never transitioned to RTK Fixed (ambiguity resolved). We're thinking that this may just be an issue with the PixHawk2.1/Here+ system. That particular client has a Phase I project starting where we'll need to build five RTK drones, so we'll be looking for an alternative to Here+. DroTek might be an option, as are a couple of other like systems. By the way, one recent study found that RTK Float gave 50-70cm accuracy, whereas RTK Fixed was 5-20cm, so we really need to be in RTK Fixed mode reliably.
