Recommendations for GNSS receivers for use within ArcGIS Field maps

[NigelGriffiths]

Hello, I am just after some recommendations for GNSS receivers with RTK capability. We are considering purchasing a Carlson BRx7, but I have noticed it requires a separate application (Carlson Layout) to enable mock location, while our previous unit (Septentrio Altus NR3) was able to be selectable as a receiver directly.

Does anyone have any experience with other GNSS receivers that work well in ArcGIS Field Maps for ~1cm level accuracy field collection, or with the Carlson BRx7 directly?

@NigelGriffiths Start with the receivers listed explicitly as compatible and then check what you can get local to you from a store with proper support.

If you want to get a device with built-in LTE/5G note that the switch-off of 3g in some places has made things complicated if the manufacturer has not pushed an update to disable 2g/3g fallback.

I've heard very good things of Emlid receivers.
