First post, and I did try looking around elesewhere for the answers but I’ve got myself confused. I was hoping someone could help guide me on a quite broad query I have please.
So I’m looking to establish a bit of a sideline interest in aerial mapping. My current research has led me to considering an RTK capable drone (e.g Phantom 4 RTK) along with using an Emlid Reach RS2+ based system for recording GCPs. Now onto my query…
I understand aerial surveying using an RTK / PPK workflow can be undertaken using one of the following configurations in order of robustness / accuracy / control.
- RTK enabled drone only, RTK corrections via a 4G dongle connected to the controller.
- RTK enabled drone with a single Emlid Reach RS2+ - The Reach would be used for recording the GCPs and would need connecting to an RTK correction service.
- RTK enabled drone with a pair of Emlid Reach RS2+ - I understand this would alleviate the need for an RTK correction service however couldn’t find a description of how all the devices would be connected.
Have I understood the basic architectures correctly? Presumably option 3 is the most robust system?
Could someone provide an idiots guide on what the optimum hardware arrangement would be?
