    High-precision RTK GNSS Receiver with Tilt Compensation

    The Reach RS3 is a versatile RTK GNSS receiver designed for surveying tasks in challenging environments. It offers tilt compensation, ensuring survey-grade precision even in difficult-to-reach locations, and supports multi-band base and rover operation. With IMU-based tilt compensation, it can make accurate measurements at tilt angles of up to 60 degrees while maintaining 20 mm accuracy. The receiver quickly initializes, provides a centimeter-accurate solution within 5 seconds, and supports various satellite systems. It has a built-in LTE modem for correction data and can work with NTRIP, CORS, and third-party bases. Dual-band radio options include LoRa and UHF for flexible connectivity. The Reach RS3 comes with software tools for field and office tasks, offers IP67 waterproofing, and features a robust industrial battery for extended usage in extreme conditions.

    Simplicity and Durability Redefined 


    No Calibration Needed


    Each Reach RS3 unit undergoes individual factory calibration, ensuring a seamless setup experience right out of the box.

    Magnetic Interference Resistance

    Unaffected by magnetic disturbances, the RS3 delivers reliable tilt compensation, even in proximity to metal structures.

    Quick Start-Up


    Tilt initialization merely requires around 20 meters of walking or 10-20 seconds of tilting, often ready before you reach your destination from the car.

    Accurate results even when dealing with large tilt angles

    Thanks to the IMU-based tilt compensation feature of Reach RS3, you can obtain measurements with a tilt of up to 60 degrees and maintain accuracy within 20 mm.

    Reach RS3 continuously monitors and adjusts for tilt in real-time to ensure you remain on target.

    Fast and Reliable GNSS receiver

    Reach RS3 can acquire a precise fix in just 5 seconds, maintaining its reliability even under conditions where the sky view is partially obstructed or when the receiver is tilted. Additionally, the device supports RINEX logging, allowing users to record raw data for post-processing with software like Emlid Studio or other RINEX-compatible applications such as OPUS, AUSPOS, and PPP services, ensuring highly accurate results globally.

    With its built-in industrial-grade battery, Reach RS3 can operate continuously for up to 22 hours on a single charge, making it ideal for extended fieldwork. Charging is made convenient through USB-C, and the device even features a built-in LTE modem, enabling the use of a SIM card for broadcasting or receiving corrections via NTRIP. Reach RS3 is a versatile and dependable GNSS receiver for various applications.

    Durable and Compact Design: The Reach RS3 boasts a rugged and compact build, measuring 126 x 126 x 142 mm and weighing in at 950 grams. It holds an impressive IP67 rating, guaranteeing waterproof capabilities up to one meter depth. All connectors are safeguarded from water and dust thanks to silicone plugs that seal them securely.

    Reliable Industrial Battery: The Reach RS3 features a robust Li-Ion battery that excels in both high and low-temperature environments. It can withstand over 2000 cycles of charging and discharging while maintaining its original capacity. This means while others are busy hot-swapping batteries, your Reach RS3 continues to work seamlessly.

    Extreme Temperature Resilience: the Reach RS3 was subjected to rigorous testing in conditions that mimic the harshest winters and hottest summers, demonstrating its operational range from -20 to +65 ºC.

    Built to Last: Crafted from polycarbonate and coated with elastomer, the Reach RS3's construction renders it impact-resistant and capable of enduring the most demanding conditions. Whether it's a fall or challenging environment, your Reach RS3 is built to withstand it all.
