For precise UAV mapping with less GCPs.
Baseline up to 100 km in PPK.
Why camera synchronization is so important?
Reach eliminates the delay
Every time a photo is taken camera produces a pulse on a flash hot-shoe connector which is synced to a shutter opening.
Reach captures flash sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory.
After the flight, get the RINEX logs from your airborne Reach module and a base station (Reach RS, CORS or another receiver).
Process RINEX files using free RTKLIB software. The produced file with precise coordinates of the photos can be used for georeferencing.
To calculate centimeter-precise coordinates in PPK and RTK, Reach needs corrections from a base station. It could be either another Reach receiver or an NTRIP service. VRS is also supported.
Reach M2 works seamlessly with other Reach receivers over any link and is compatible with any other receiver that supports RTCM3 and NTRIP.

As a brief synopsis of the results, the maximum deviation of points was no more than 0.09m in all axes.
This is an incredible result given the fact that the average pixel size of the resulting imagery was 0.045m. The average mean error in all axes is just few mm!
Tuffwing recently performed integration of Emlid Reach RTK to enable precision maps to be made without the use of GCPs. The system has been benchmarked by comparing a direct georeferenced model with a set of GCPs, used solely for error detection purposes. The lateral RMS error achieved is just 4cm according to the Pix4D quality report.
In this case study, we produced an orthomosaic in the Drone Data Management System™ with 2.45cm horizontal and 5.08cm vertical RMSE, as compared with a survey-grade GPS on the ground.
