REACH M2/M+

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

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.

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

Choosing between
Reach M+ and Reach M2

Reach M+
and Reach RS+

If you work within short baselines, then Reach M+ is an optimal choice.

Reach M2
and Reach RS2

Provides robust performance and quick initialization, allowing work on long baselines.
