Emlid Reach RS3 is a survey-grade, multi-band RTK GNSS receiver with IMU tilt compensation—so you can capture accurate points even when the pole isn’t perfectly vertical. Run it as a base or rover, connect via built-in LTE for NTRIP, and work end-to-end with Emlid Flow/Flow 360 for a simple field-to-office workflow.
Key highlights
-
Tilt to 60° with ~20 mm accuracy for hard-to-reach points and faster stakeout.
-
Dual-band UHF (868/915 MHz) for base/rover where there’s no internet; full NTRIP support when there is.
-
Built-in LTE modem (3G/2G fallback): pop in a SIM to receive or broadcast corrections.
-
Long battery life: up to 18 hrs as an RTK rover (up to 22 hrs logging).
-
Rugged, weatherproof: compact, impact-resistant body, IP67 rated.
-
Survey-grade outputs: RTK/PPK capable with RINEX logging for OPUS/AUSPOS/PPP services.
