About This Item:

The Emlid Reach RS4 Pro All-Band RTK GNSS Receiver is a next-generation surveying tool designed for high-precision geospatial data collection in complex environments. Equipped with dual Full HD cameras, it enables visual stakeout and remote point capture, allowing users to measure inaccessible locations such as building facades, fenced areas, or across busy roads. The RS4 Pro supports all major satellite constellations and signal frequencies, including L1, L2, L5, and L6 bands, and tracks over 40 satellites simultaneously using 672 channels. Its advanced tilt compensation system maintains accuracy even at steep angles, eliminating the need for manual pole leveling.

This receiver is ideal for professionals in construction, utilities, mapping, and infrastructure development who require fast, accurate, and flexible surveying capabilities. The RS4 Pro integrates augmented reality guidance for stakeout tasks, improving speed and clarity on job sites. Built with a rugged magnesium alloy body, it is IP68-rated for water and dust resistance and operates in temperatures from -40°C to +65°C. With up to 16 hours of battery life and USB-C charging, it supports uninterrupted fieldwork. The RS4 Pro connects to VRS or CORS networks and can transmit corrections via NTRIP, LoRa, or UHF, making it a versatile solution for modern survey workflows.

Dual Camera

 

Stake out faster with AR

With the RS4 Pro, stakeout becomes visual.
Rather than simply following coordinates on
a map, your designs are directly overlaid on the
real world, clearly showing where to place stakes.
Crews can work faster with AR guidance, even 
on complex construction sites and roadworks.

Measure from images

Even if you can't put the pole on that point,
you can still measure it with your RS4 Pro.
Use the cameras to measure building facades,
areas behind fences, across busy roads and any
other inaccessible points. Save time setting up
a total station and avoid hazardous areas.

  

 

 

The Reach RS4 Pro delivers centimeter-level accuracy, even in challenging environments like forests or urban canyons. With support for every GNSS constellation and signal frequency, including the L5 and L6 bands, resistant to multipath and interference, the Reach RS4 Pro locks onto 40+ satellites simultaneously using 672 channels.

 

The Reach RS4 Pro is powered by Emlid Flow—a complete field and cloud solution for iOS and Android. From initial setup to final verification, Emlid Flow keeps your entire team connected, your data synchronized, and your project on track.
