The Emlid Reach RS3 Survey Kit bundles two RS3 receivers for a complete, field-ready RTK base and rover setup. With IMU-based tilt compensation on both units, centimetre-accurate surveying is possible at up to 60° of tilt — no levelling required. Everything you need to start collecting survey-grade data is included straight out of the box.
A complete RTK system in two cases — set up your base, grab your rover, and get to work.
Features
- Includes two Reach RS3 receivers, pre-configured for use as a base and rover pair over LoRa radio — no additional hardware required
- IMU-based tilt compensation on both units allows accurate point collection at up to 60° of tilt, speeding up work at building corners, walls, and hard-to-reach locations
- Calibration-free and immune to magnetic disturbances — reliable tilt performance even near metal structures and reinforced surfaces
- LoRa radio link provides up to 8 km base-to-rover range; both units also support LTE NTRIP for CORS network connectivity
- PPK-capable with RINEX logging on both receivers — compatible with Emlid Studio, OPUS, AUSPOS, and third-party PPP services
- Up to 22 hours battery life per unit; charges via USB-C and accepts external power banks for multi-day fieldwork
- IP67 waterproof and impact-resistant, rated from -20 to +65°C for demanding survey environments
- Managed through Emlid Flow for field data collection, stakeout, and team collaboration — free to use with optional subscription upgrade
