If you cannot clear the ground area of grass, maybe drive some tall stakes with specialty made mounts for GCPs? Or maybe a cable attached through GCP via hole, washer with weight at bottom? (Edit: depending on how lush the grass is, hopefully thick enough to support the GCP, may need more than one anchor point to prevent GCP movement due to wind, earthquakes, wild boars, monkeys, crocodiles, or even raptors ) Is elevation not important? Seems you would have an elevation offset.
So you need to make a portable fencepost with a GCP on top?
What about using a broom handle / small post / piece of lumber? Attach a square of plywood or hardboard to the top. Or if your GCP is solid enough, just screw it to the post.
For stability just use three pieces of string as guy wires. If the crops are sturdy, then tie to the base of the plant. If not, then use tent pegs. If the soil is loose then get the spiral anchors that look like corkscrews or just bring a hammer and some wooden stakes.
You are bringing back memories…
(that are somewhat relevant)
FYI: The linked post below was prior to Reach RS2, Reach M+, Reach RS+, and Reach RS. It was back in the olden days when there was only the Reach RTK kit (small modules) and only one flavour of ice cream and the pictures were all taken in black and white.
…well OK, maybe not that long ago but it seems like it.
Depending on what part of the world you’re in, you could always have about 6 locals all the same height hold it on the top of their head like a hat for a beer each? Tell them if they move it explodes.
People will do ANYTHING for a beer.
Bought a few different poles to test out in the crops today.
A 20 mm x 1500 mm pole was the over all winner.
large diameter tube made is less prone to flexing both in the ground and in the material.
lighter weight than a solid 12 mm diameter steel rod
more real-estate to mount the GCP on on top.
1500 mm is needed for ready-to-harvest rapeseed. Roughly 30 cm can go into the ground before it starts touching the top of the crops.
Getting the required GCP’s into the field is gonna be a nightmare though! walking isn’t an option, way too many combined kilometers in a day. Will ask the farmer if he can help us, as no ordinary vehicle can span the tractor-tracks.
