Reach M2 – RTK GNSS module for UAV mapping. Positioning with centimeter accuracy in RTK and PPK. For precise UAV mapping with less GCPs
Reach M2 is a compact and lightweight multi-band RTK module for real-time navigation and PPK mapping.
Reach M2 tracks GPS/QZSS (L1, L2), GLONASS (L1, L2), BeiDou (B1, B2), Galileo (E1, E5) and SBAS (L1C/A) and gets fixed solution almost instantly. Reach M2 allows working over longer baselines (compared to a single-frequency Reach M+), up to 60 km in RTK and up to 100 km in PPK mode.
Designed for UAV Applications
Being compact, Reach M2 can be easily integrated into a UAV platform. Reach M2 connects to a camera via hot shoe and records the location of each photo with the update rate up to 20 Hz. Ultimately, it produces more detailed and consistent data set for the further georeferencing at various professional mapping software.
Helical GNSS Antenna
Modern helical antenna compliments Reach M2 and operates across the same satellite constellations, so you won’t miss a satellite. Helical antenna eliminates the need in large ground plane yet allows to achieve high positioning accuracy.
Configuration and Logs Management with ReachView
Reach M2 can be configured via ReachView app, available both for Android and iOS. The app allows to set up RTK settings, collect raw data in RINEX format, and control all the features of the device
Use Reach RS2 as a base station
Reach M2 works seamlessly with other Reach receivers over any link. It is also compatible with any other receiver that supports RTCM3 and NTRIP.
PPK system for UAV mapping
with centimeter accuracy
Reach logs precise tracks and the exact moment when each photo is taken.
This allows to cut number of checkpoints and create precise 3D models.
How Does It Work?
1. Reach connects to the
camera hot shoe port
which is synchronized with
accurate photo time marks
are stored in a raw data
RINEX log during the
3. Download the RINEX logs
from your airborne Reach
module and a base station
after the flight
4. Use the free RTKLIB
software to process RINEX
files and get a list of precise
RTK positioning for navigation
Reach M2 provides more robust performance
and quicker initialization compared to Reach M+.
Both receivers provide centimeter accuracy
in RTK and PPK modes.
