Emlid RTK GNSS receivers for centimeter-level positioning.
Emlid makes Reach RTK GNSS receivers and the field software that drives them. Cleartopia helps survey, construction, GIS and drone mapping teams put Reach to work, from base stations and ground control to stakeout and PPK.
Where Emlid fits
Reach receivers bring survey-grade positioning to field crews at an accessible price. They track every major satellite constellation, work as a base or a rover, and pair with the Emlid Flow app for collection, stakeout and cloud sync. For drone work, a Reach base and a second receiver for ground control points give you accurate results with RTK or PPK aircraft, even without cell coverage.
Common uses
- Base station and GCP collection for drone mapping
- Topographic and land surveys
- Construction layout, stakeout and as-builts
- GIS data collection with ArcGIS Field Maps, QField and similar apps
- Mobile terrestrial scanning with a smartphone and Reach RX2

The Emlid lineup
Specifications and availability are set by the manufacturer and can change. We confirm current models, kits and pricing when we scope your project.
Reach RS4 Pro
Emlid's flagship all-band receiver, with dual Full HD cameras for AR stakeout and measuring points from images where a pole cannot go. Emlid rates it at 7 mm + 1 ppm in RTK, with tilt compensation, up to 16 hours of battery, LoRa, UHF and NTRIP connectivity, and an IP68 magnesium body.
Reach RS4
The same all-band GNSS engine and tilt compensation as the RS4 Pro, without the cameras. A strong base and rover for topo surveys through design set-out, with LoRa, UHF and NTRIP and up to 16 hours on a charge.
Reach RX2
An ultralight 280 g rover with tilt compensation for GIS mapping, layout and smartphone-based terrestrial scanning. It works with NTRIP corrections and pairs with common field apps.
Reach M2
A compact multi-band RTK and PPK module for drones. It logs camera events directly from the shutter for precise photo geotags, so ground control can be used mainly for checking accuracy.
Emlid software
Emlid Flow for receiver setup, collection and stakeout on iOS and Android, Emlid Flow 360 for cloud project sync, and Emlid Studio for free PPK and drone photo geotagging. Emlid Corrections adds an RTK service with no base station required.
