The EMLID Reach RS4 Pro is an all-band RTK GNSS receiver with dual cameras for visual stakeout and remote point capture for faster and safer work. It also features tilt compensation (IMU) that maintains ultimate precision even in challenging conditions and under dense tree canopies. It offers RTK accuracy of 7 mm + 1 ppm, and with tilt compensation achieves 2 mm + 0.3 mm/° precision. Operating as both base and rover, it supports 915 MHz LoRa and 450 MHz UHF NTRIP communication.
Powered by a Li_Ion battery, the RS4 Pro runs up to 16 hours on a single charge, with USB Type_C charging available. Its magnesium alloy body, IP68 dust_ and waterproof rating, and wide operating temperature range from _40 °C to +65 °C make it ideal for harsh field conditions.
Discover the new way to survey with dual cameras
The Reach RS4 Pro introduces a new way to survey with its dual Full HD cameras, extending capabilities beyond traditional RTK. Stakeout is faster and more intuitive with AR guidance, as your design is overlaid directly on the real world, showing exactly where to place stakes rather than just following a map. Features like dynamic navigation, auto bullseye view, cut & fill indicators, and quick point switching help crews work more efficiently, even on complex construction sites and roadworks.
The RS4 Pro also enables measurement from images, allowing you to capture data from locations where you cannot place the survey pole. Building facades, areas behind fences, across busy roads, over water, past hedges, above pits, and around machinery can all be measured without physical access. This eliminates the need to set up a total station for such tasks and helps avoid hazardous areas.
Unmatched Precision
With 672 channels, the EMLID Reach RS4 Pro can track 40+ satellites at a time from all major constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC). With support for L1, L2, and the lower L5 and L6 band frequencies, it ensures strong multipath resistance and reliable signal reception. The Reach RS4 Pro thus delivers reliable performance and centimeter-level accuracy with 7 mm + 1 ppm precision in RTK mode. The receiver achieves a fixed RTK solution in less than 5 seconds, providing fast and dependable positioning in the field.
Next-gen tilt compensation
The Reach RS4 Pro comes factory_calibrated, ensuring instant readiness with no need for field adjustments. Its tilt compensation works reliably under all conditions and is immune to magnetic interference, maintaining accuracy even near metal objects. With faster initialisation and no angle limit, it provides precise measurements even at steep tilts. The compensation mechanism activates with just a few moves and remains stable throughout the survey, saving time and avoiding the need for recalibration.
Base and rover connectivity
The Reach RS4 Pro can operate as both base and rover, supporting RTK work with VRS or a single baseline CORS network in RTCM3 format. You can also connect another GNSS receiver as an NTRIP base using EMLID NTRIP Caster. It features a dual_band radio system:
· UHF 450 MHz for transmit and receive, with up to 2 W output (may require a license), compatible with Reach and 3rd_party receivers that support TRIMTALK 450S.
· LoRa 915 MHz for transmit and receive, with up to 1 W output (license_free in North America), compatible with Reach receivers.
Engineered for the harshest environments
The Reach RS4 Pro's magnesium alloy body is both light and exceptionally durable, similar to materials used in aerospace and high-end electronics. This combination ensures strength and ease of handling, even in the toughest environments. With up to 16 hours of continuous operation on a single charge, the RS4 Pro is designed for long field days. It can be recharged via USB-C or powered by a portable power bank for added flexibility.
Thanks to its IP68 rating, the receiver is completely dustproof and waterproof, continuing to operate reliably in rain, snow, or dusty construction sites. Operating temperatures range from -40°C to +65°C, ensuring consistent performance in both extreme cold and intense heat.
Software for every stage of your project
The Reach RS4 Pro includes EMLID Flow, a complete mobile and cloud-based solution compatible with iOS and Android. It keeps your team coordinated and your projects running smoothly while supporting all essential site tasks.
With EMLID Flow, you can coordinate your team by inviting members, sharing projects, and managing access.
