How does the Emlid Reach M2 module work?

Reach connects to the camera hot shoe port which is synchronised with the shutter.

Sub-microsecond accurate photo time marks are stored in a raw data RINEX log during the flight.

Download the RINEX logs from your airborne Reach module and a base station after the flight.
