NEW
Reach RS4 Pro
All-band RTK GNSS receiver with dual cameras and centimeter precision
New antenna all band (L1-L6)
Next-gen tilt compensation
New module LoRa/UHF 10x more powerful
Two Full-HD cameras
Comes with the Emlid Flow mobile app (Android/iOS
Measure from images
Use the cameras to measure building facades, areas behind fences, across busy roads and any other inaccessible points. Save time setting up a total station and avoid hazardous areas.
Stake out faster with AR
With its cameras, combined with the power of the Emlid Flow application, layout becomes effortless.
Upload your files (.csv / .dxf / .shp / .kml) directly via the Emlid Flow app and let your receiver guide you precisely to the point to be set out.
Getting closer! The second camera, facing the ground, is then activated, allowing you to visually pinpoint the exact location of the point to be staked out.
New GNSS antenna
The Reach RS4 Pro range features a brand-new full-band GPS antenna (L1–L6) and a magnesium housing, designed to reduce interference.
Reliable GPS signal reception under vegetation cover is now possible. Positioning is achieved within seconds, while maintaining robust performance even in challenging environments.
Centimeter-level accuracy can be achieved over distances of up to 60 km in RTK mode and up to 100 km in PPK mode.
GPS Signals:
GPS: L1C/A, L2C, L5
GLONASS: L1OF, L2OF
Galileo: E1-B/C, E5a, E6
BeiDou: B1I, B1C, B2a, B3I
QZSS: L1C/A, L1C/B11, L2C, L5
NavIC: L1-SPS Data, L5-SPS
Next-gen tilt compensation
The Reach RS4 & RS4 Pro feature a brand-new tilt compensation system (IMU), with an initialization phase reduced to just a few seconds. This enables high-quality data acquisition in hard-to-reach locations such as building corners, tree bases, and similar environments.
This in-house Emlid technology delivers industry-leading accuracy of RTK + 2 mm + 0.3 mm/°, all within a factory-calibrated IMU for true out-of-the-box operation.
Emlid’s internal testing shows that the tilt-compensated GNSS performance of the Reach RS3 outperforms competing high-end receivers, making it the most accurate, affordable, and user-friendly solution on the market.
New LoRa module — 10× more powerful
Equipped with a low-power LTE modem with 2G/3G fallback and worldwide coverage.
Corrections can now be accessed or broadcast via NTRIP independently, without relying on an internet connection from your phone.
22 hours on a single charge
Up to 22 hours of autonomous operation during data logging and up to 16 hours when used as a 3G rover, even in cold weather — no need to carry spare batteries.
The Reach RS4 Pro can be charged using a USB wall charger or a power bank via USB-C.












Save up to 5× more time with tilt compensation
