Reach RS4 & RS4 Pro: Power and Innovation
The new RS4 series represents a massive leap in RTK technology, designed for maximum reliability and speed.
Core RS4 Series Upgrades (RS4 & RS4 Pro):
Uncompromised GNSS Performance: Now tracking all satellite constellations and frequency bands (L1/L2/L5/L6) with 672 channels, ensuring a fast and stable fix in under 5 seconds, even in urban canyons or under canopy.
Next-Gen IMU Tilt Compensation: The second-generation IMU initializes up to 5 times faster than previous models, delivering reliable centimeter-level accuracy without the need to level the pole. It’s factory-calibrated and immune to magnetic interference.
Rugged & Durable Design: Both receivers are housed in a robust Magnesium Alloy body, boast an IP68 ingress protection rating, and operate in extreme temperatures (-40∘C to +65∘C).
Enhanced Connectivity: Features an integrated antenna system with a multi-band radio (LoRa and UHF up to 2W) for base-to-rover communication and an upgraded LTE modem, dual-band Wi-Fi, and Bluetooth 5.1 for robust network connectivity
Reach RS4 Pro: The Visionary Flagship
El Reach RS4 Pro takes surveying beyond traditional RTK by integrating dual, factory-calibrated Full HD cameras:
Augmented Reality (AR) Stakeout: Overlay your CAD designs and points directly onto a live camera view in the Emlid Flow app, making navigation and stakeout intuitive, visual, and significantly faster.
Measurement from Images: Safely capture inaccessible points—such as building facades, points across a busy road, or dangerous locations—by simply taking and processing an image through the on-board cameras.
Reach RX2: The Pocket-Sized Powerhouse
The new Alcance RX2 evolves the ultra-portable rover concept, making professional precision even more accessible:
All-Band Performance in Your Pocket: Despite its compact size (280g), the RX2 features the same All-Band RTK support as the RS4 series for superior performance in obstructed areas.
Integrated Tilt Compensation: Now includes second-generation IMU tilt compensation, allowing for accurate, level-free measurements.
Simplicity and Speed: Designed as a zero-configuration network rover. Simply power it on and connect to the Emlid Flow app to start surveying—no settings to configure.
Seamless GIS Integration: Fully compatible with leading GIS apps like Esri ArcGIS Field Maps and Pix4Dcatch for mobile scanning.
