Robot to controller range
Can't find many manufactures who will state a maximum range from robot to controller even for line of sight with no obstructions etc.
Be interested to know what others get? Too start the ball rolling a Leica tcrp1205 with external tcps27b radio and rx1200 controller won't get over 200m. It does have a bit over a decade under its belt though.
So what's the best your setup does in the real world?
It's normally the tracking rather than the radio which limits the range. The old GDM4400 used to manage 400+ metres, GDM640 and Trimble 5605 manage 350ish. I'd plan the survey to stay say 50 metres inside expected range. Then any extra is a bonus and timesaver. Once the range starts to struggle it's generally better to move to the next station rather than mess on forever.
The only time I get radio dropout is close to some interference source - typically data streaming units on pumping stations etc. A real pain on landfill sites.
My Spectra Precision Focus 35 is good for 1000-1200 feet using the 2.4 ghz radios. I know that a Trimble S6 is good for more than that, possibly 1200 to 1500 feet or more. So far my S5 is good to 21 feet but I just got it last week and it hasnt made it outside.
Trimble S6 & S7 with Yuma2 & Yuma 7 will track the Mt1000 out to 2500-2600 ft and the radio will reach out to 3500-4000 ft with no obstructions. On the rare occasion where I need to shoot optical beyond MT1000 range I switch to a 62mm prism and go get it.
