REACH M2

RTK GNSS modules for UAV mapping
Positioning with centimeter accuracy in RTK and PPK.
For precise UAV mapping with less GCPs

PPK mapping with centimeter accuracy. Use fewer GCPs

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

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 work seamlessly with other Reach receivers over any link and are compatible with any other receiver that supports RTCM3 and NTRIP.

Comes with an app

ReachView is the most user-friendly software for data collection that is available both for Android and iOS. With ReachView, you can control all the features of Reach receivers, such as setting up a base station, logging RINEX data, configuring NMEA output, and monitoring data.

Camera
control

Reach is able to trigger cameras as well as register events. The event mark feature is a must for aerial mapping as it allows the precise time when the shutter was activated to be registered.

Simple log
management

Logs are automatically recorded directly to RINEX in the internal memory. View a list of the logs and download them using the ReachView app.

Monitoring
data

ReachView shows current satellite levels, your location on a map, and much more.
