Hey folks, just a quick and simple question for anyone who may have used an M2 on a roving pole or tripod. I’m measuring a PPP with an M2 in a MettaTec base kit set on a tripod over a static point. I’m curious what value to use for antenna height. I want to assume when logging while connected to an M2, ReachView 3 will not automatically calculate an offset like it would if it were connected to an RS2 or RS+. Am I correct about this? Therefore I should enter the total measured pole height + the offset value for the MettaTec box, which is 161.2mm (16.12 cm), as my antenna height correct or no?
If anyone can affirm I’m on the right slant here I would be very grateful.
I did ask Mettatec, … they supplied the antenna offset which is 0.1612m.
What I’m asking here is, … does Reachview3 app automatically calculate an offset value when connected to an M2 like it does with RS receivers. I suspect it would not because the M2 is designed to be mounted on a UAV as apposed to a pole or tripod, but I just want to confirm this in which case the antenna height would be the measured pole or tripod height plus this provided offset.
I see Dave already correctly answered your question, but I want to provide some details.
Almost all antennas have an antenna phase center offset. And you need to add it to the survey pole/tripod height. ReachView 3 does that automatically for Reach RS2/RS2+/RS+ because it knows the device model.
Yes thx Svetlana. I knew that about the RS receivers, and assumed it probably wouldn’t apply to the M2 but just wanted to confirm for certain. I have the antenna offset for the MettaTec enclosure and have added it to my survey pole/tripod height.
