Emlid hardware solutions
Precision GNSS receivers for every workflow
Emlid’s GNSS hardware range covers compact rovers to advanced multi-purpose receivers:
Reach RX & RX2: Ultra-portable network rovers — ideal for quick site visits, asset capture, and GIS mapping.
Reach RS3: A proven all-round GNSS receiver with reliable tilt compensation and robust radios for base/rover roles.
Reach RS4 & RS4 Pro: Next-generation all-band RTK receivers with enhanced IMU tilt, stronger radio performance, and rugged build. RS4 Pro adds integrated dual cameras for AR stake-out and image-based measurements.
Emlid RS4 Pro vs RS4 vs RS3
Which GNSS receiver is best for you?
Emlid RS4 Pro | Emlid RS4 | Emlid RS3 | |
|---|---|---|---|
GNSS support | All-band RTK | All-band RTK | Multi-band RTK |
Channels | 672 | 672 | 184 |
IMU tilt compensation | Advanced, fast | Advanced, fast | Standard |
Cameras/AR | Dual integrated cameras — AR stakeout & visual capture | No | No |
Radio | LoRa + UHF bi-directional | LoRa + UHF bi-directional | LoRa/UHF (varies) |
Durability | IP68 | IP68 | IP67 |
Best for | Complex set-out & inaccessible points | Everyday survey & construction | Trusted all-round fieldwork |
The RS4 series represents a significant step up over the RS3 with improved signal tracking, faster tilt fixes, and better connectivity. The RS4 Pro builds on that foundation with vision-based workflows that can redefine stake-out and measurement tasks.
Emlid RX2 vs Emlid RX
Which lightweight rover is best for you?
Emlid RX2 | Emlid RX | |
