Using RTK GNSS on drones has always been a bit complicated for us: the setting up process tends to be long and tedious. It also has been time consuming to validate if all the settings implemented from different forum threads offer a reliable solution and to debug errors.

Because time is money - we have ended up developing a PCB that we use on our drones that makes it very easy to use RTK GNSS. It works straight out of the box if the base station is connected to the GCS (we fly with Ardupilot, but it should work the same with PX).
The default fall-back is not GPS but Egnos: which also increases accuracy and reliability.
It's also possible to use RTK correction signal networks, but this of course takes a bit more setting up.

I am wondering if there would be people and aerial mapping companies interested in buying this type of hardware? Would it make sense for us to release it as a product?
