Emlid Reach M2 RTK GNSS module

The Emlid Reach M2 is high-precision RTK GNSS modules for drone mapping

Achieve positioning with 1 centimetre accuracy in RTK and PPK, and use less GCPs.

The Reach M2 is a multi-band RTK GNSS module, with a baseline of up to 100km in PPK.

Emlid Reach solutions are available as stand alone modules or as part of dedicated UAV mapping kits. 

PPK System for UAV Mapping with Centimetre Accuracy

Use fewer GCPs

Reach logs precise tracks and the exact moment when each photo is taken.

The time and coordinates of each photo are logged with a resolution of less than a microsecond.

This means that the number of checkpoints can be reduced - and allows GCPs to be used only to check your accuracy - and enables the creation of precise 3D models.

How it works

Reach connects to the camera hot shoe port which is synchronised with the shutter.

Sub-microsecond accurate photo time marks are stored in a raw data RINEX log during the flight.

Download the RINEX logs from your airborne Reach module and a base station after the flight.

Use the free RTKLIB software to process RINEX files and get a list of precise photo coordinates.

Compatibility

To ensure smooth synchronisation of Reach and a camera, we recommend you use the Reach M+/M2 hot shoe adapter. You can get it with the UAV kit or separately.

The PPK modules are fully compatible with most cameras with hot shoe including:

  • Sony A6000
  • Nikon D3200
  • Canon EOS 4000D
  • Canon EOS 700D DSLR
  • Ricoh GR III
  • Sony Alpha A7R III
  • Samsung NX1000

Connectivity

Reach needs corrections from a base station to calculate centimetre-precise coordinates in PPK and RTK.

Use Reach with another Reach receiver or an NTRIP service. VRS is also supported.

Reach M2 and M+ work seamlessly with other Reach receivers - such as Reach RS2 and RS+ - over any link and are compatible with any other receiver that supports RTCM3 and NTRIP.

ReachView 3 App

Powerful data collection software for Emlid Reach

The ReachView 3 app is a user-friendly data collection software. It is available for Android and iOS.

It supports thousands of coordinate systems and is translated into multiple languages.

With ReachView 3, you can control all the features of Reach receivers, such as setting up a base station, logging RINEX data, and configuring NMEA output. ReachView also triggers cameras as well as registers 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.
