Emlid REACH RS3 The Emlid REACH RS3 is a professional-grade GNSS receiver designed to deliver survey-grade precision in challenging and hard-to-reach environments. Combining advanced tilt compensation, multi-constellation satellite support, and versatile connectivity options, it empowers surveyors to achieve fast, reliable, and accurate positioning with ease. The included mobile app enhances productivity by enabling real-time data visualization and streamlined field workflows. High-Precision IMU with Tilt Compensation Equipped with a 6DOF inertial measurement unit (IMU), the REACH RS3 provides RTK accuracy of 2 mm + 0.3 mm/°. This advanced tilt compensation allows users to perform accurate measurements without leveling the pole, boosting efficiency and ease of use. Comprehensive GNSS Support The receiver supports multiple satellite constellations: GPS, QZSS, GLONASS, BeiDou, and Galileo. This multi-frequency tracking enhances satellite availability and positioning reliability worldwide, ensuring robust performance in diverse surveying scenarios. Long Battery Life and Convenient Charging Powered by a durable Li-Ion battery, the REACH RS3 offers up to 18 hours of operation with tilt compensation enabled. Its USB Type-C charging provides fast and convenient power replenishment for extended fieldwork. Robust Connectivity Options The REACH RS3 features built-in LTE and Wi-Fi for seamless internet connectivity, alongside dual-band radios: 868/915 MHz LoRa for two-way correction communication and 450 MHz UHF for receiving corrections. It supports NTRIP and RTCM3 protocols, facilitating reliable sending and receiving of correction data essential for precise positioning. User-Friendly Mobile App A dedicated mobile app complements the hardware by providing intuitive control, real-time data visibility, and simplified workflow management. This makes the REACH RS3 an ideal tool for professionals seeking accuracy, flexibility, and ease of use in demanding survey conditions.
