PPK mapping with centimeter accuracy. Use fewer GCPs
Most GIS apps accept data in the standard NMEA format, which Reach delivers. Connect your device to Reach through Bluetooth or a cable, then enable "Position output" in ReachView.
Why camera synchronization 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 readings 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 the 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
Most GIS apps accept data in the standard NMEA format, which Reach delivers. Connect your device to Reach through Bluetooth or a cable, then enable "Position output" in ReachView.
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.
Compatibility
Reach M2 works seamlessly with other Reach receivers over any link and are compatible with any other receiver that supports RTCM3 and NTRIP.
Choosing between Reach M2 and Reach M+
Reach M2 UAV mapping kit
Reach M2, Reach RS2, and GNSS antenna are included in the Reach M2 UAV mapping kit, offering robust performance and swift initialization for extended baseline operations.
Reach M+ UAV mapping kit
If you operate within short baselines, the optimal choice is the Reach M+ kit, which includes Reach M+, Reach RS+, and a GNSS antenna, ensuring robust performance and quick initialization.
