Hello, I am very new to all of this but was looking for a product recommendation for my use case. I am working on base maps for ~1-2 acre properties and am using a Bluetooth RTK Module from ArduSimple. I can occasionally get to FIX accuracy, however connection quickly gives out around trees and houses. I am looking for a simple base station I can set up within a few minutes from my car so my scanner can get ~1 cm accuracy. What is the easiest and cheapest way to go about this?
Welcome @Cael !
Answers can range from fairly simple to extremely complicated, depending on what you need to accomplish from the GNSS positions, and if you truly mean “1 cm Accuracy”.
Is the main intention (of the RTK points) to geolocate the final output (3D model) from the scans?
Or do you intend to use the RTK points (targets) during the 3D model reconstruction as Hard Control Points ?
I’m only asking because both are valid uses, but have very different requirements and workflows.
What correction source are you using currently?
Having a local base doesn’t provide much magic or immunity to obstructions experienced by your Rover such as the trees and houses you mentioned. A shorter baseline does have advantages, but not without taking a lot of care in establishing the initial Base Position… if absolute accuracy is a specific goal.
There are many situations were a Local Base can quickly be established via RTN as a Network Rover, then operated as the Local Base providing short-range observations/corrections to a Rover. I’m “guessing” that’s what your looking for based on our post, but that’s just a guess at the moment

Thank you for the reply! My goal is to convert the RTK points to a 3d model, however absolute coordinates aren’t necessary, as long as they are relative (for ex, how far the house is from trees on the property, what the elevation of the garage is relative to the street, etc.) I’m currently using RTK2GO, and can usually get within reach of ~25 satellites or so. Its just very difficult to keep Fix accuracy with any sort of obstruction. Here is the link to what I am currently using, along with SW Maps
I think our Facet L-Band might suit your use-case perfectly - check out the features and our intro video for more info 
Thank you Russell! I would prefer something that would work with the rover I already have, so just a compatible base station of the sort, or maybe a more accurate antennae (as I said I am very new to all this so I don’t know the best approach. )
Here is what I am currently working with
That product page describes a Network Rover and doesn’t mention any form of radio to use with a local base.
would it not still be compatible? In the product description it says “Base and Rover functionality”
Antennas with reject multipath are described here https://sites.calian.com/app/uploads/sites/8/2024/09/Calian-Product-Brochure-EN-2024-WEB.pdf
The first page is particularly useful as it indicates in a blue circle which type of antenna to choose according to accuracy.
