I’m working with a different project now though where:
(A) I only need accuracy of around 0.5m in open-sky conditions and
(B) I need it to be as cheap as possible and
(C) data needs to be pulled in real time (so no PPK) as its for a tractor-like system.
I’m wondering if an RS+ would be accurate enough in float. But even then, I’d like a cheaper unit. I’m guessing the M+/M2 won’t work as I need the data in real time.
Perhaps I need to look at other solutions beyond EMLID?
The solution suggested by @TB_RTK looks interesting!
I just want to clarify that Reach RS+ in standalone mode can provide coordinates with a few meters accuracy only. Also, Reach M+ and Reach M2 can work in RTK and don’t differ in accuracy from Reach RS+.
There should be no issue with Reach RS+ and Reach M+ couple in RTK. Just keep in mind that these devices are single-frequency, which means they require a clear sky view without any obstacles. Also, the maximum distance in RTK for single-band receivers is 10 km.
