Reach M+ RTK GNSS module for precise navigation and UAV mapping $265

Reach M+ is a compact and affordable multi-GNSS RTK receiver with built-in IMU for precise navigation and UAV mapping without GCP. It can provide coordinates down to centimeters in RTK mode. RTK mode requires a pair of receivers: one is stationary which provides corrections, another one moving which applies corrections and provides its precise coordinates. Reach M+ runs open-source RTK engine “RTKLIB” written by Tomoji Takasu.


Reach M+ package includes:

  • 1 x Reach M+ module
  • 1 x USB cable
  • 1 x USB-OTG cable
  • 1 x JST-GH 6-pin to jumper pin cable
  • 1 x JST-GH 5-pin to jumper pin cable

PPK system for UAV mapping.
Centimeter accuracy without GCP

Reach M+ logs precise tracks and the exact moment when each photo is taken. This allows to create precise 3D models without complicated ground control preparations drastically simplifying the mapping process.

How Does It Work?

Image

Reach M+ connects to the camera hot shoe port which is synced to the shutter.

Image

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

Image

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.

RTK positioning for navigation

When provided with corrections from the base station Reach M+ calculates coordinates with centimeter accuracy in real-time and streams them in industry standard format to your drone or any other device.
