PPK mapping with centimeter accuracy.
Why camera synchronizations is so important
Usually autopilot triggers the camera and records the coordinate it has at that moment. When the drone is flying at 20 m/s and GPS works at 5 Hz, that means your autopilot will have position reading only each 4 m, which is not suitable for precise georeferencing. In addition, there is always a delay between the trigger and the actual moment the photo is taken.
Reach eliminates the delay
Reach solves the problem of positioning by connecting directly to the camera hot shoe port, which is synced with the shutter. The time and coordinates of each photo are logged with a resolution of less than a microsecond. This method allows GCPs to be used only to check your accuracy.
1. Connect Reach to a hot shoe port on a camera
Every time a photo is taken camera produces a pulse on a flash hot-shoe connector which is synced to a shutter opening.
2. Fly a drone, Reach will record photo events
Reach captures flash sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory.
3. Download logs from Reach and base station
After the flight, get he RINEX logs from your airborne Reach module and a base station (Reach RS, CORS or another receiver).
4. Process logs and get a file with geotags of photos
Process RINEX files using free RTKLIB software. The produced file with precise coordinates of the photos can be used for georeferencing.
NTRIP or another Reach as a base station
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 M+ works seamlessly with other Reach receivers over any link and are compatible with any other receiver that supports RTCM3 and NTRIP.
If you work within short baselines then Reach M+ is an optimal choice.
