Does Reach M2 require corrections from a base station?
Yes, Reach M2 requires corrections from a base station to calculate centimetre-precise coordinates in PPK and RTK. Use Reach with another Reach receiver or an NTRIP service. VRS is also supported. Reach M2 works seamlessly with other Reach receivers - such as Reach RS3 - over any link and is compatible with any other receiver that supports RTCM3 and NTRIP.
