I understand if base is older than rover, less sats will be tracked/used by rover. ?ÿThat being said, is it a bad idea to mix older base with newer rover? Currently own a BRX5 and thinking of adding a BRX6+ or 7. ?ÿIs this a bad idea? Would I be better off with a pair of the same unit. ?ÿNewer rover would be used on NCRTN possibly 50% of the time. ?ÿSuggestions?
The Base needs to be broadcasting the corrections for all the satellites the Rover is receiving. If it's doing that the newer Rover I the way to go since it may have an updated firmware for calculating fixed positions. That's the simple man's explanation. I would expect the genius's to soon reply with a more complex and precise explanation.

What is important here is the number of satellites that are tracked by both receivers at the same time.
If base and rover are tracking their max capacity that doesn't guarantee they are the same sats, unless they are both tracking all that are usable at that time.
Changing only one receiver to a model that that tracks more satellites could thus be marginally beneficial because it would be more likely to be tracking all those the lesser receiver was. You could upgrade to the newer model one at a time.
But there is also an accuracy improvement if both antennas have the same phase pattern, although modern calibrations have lessened that worry, and I haven't researched how similar those models are.
