Emlid Reach RS4 Pro Weekly Rental

Emlid Reach RS4 Pro brings all-band RTK GNSS, dual cameras, and AR stakeout to professional survey and construction workflows, enabling field teams to capture centimetre-accurate points in locations they cannot physically access.

• Measure points you cannot reach: Dual Full HD cameras let you capture coordinates across roads, over fences, above pits, and past machinery directly from images without requiring a total station.
• Stake out in augmented reality: Overlay your CAD design onto the live scene so crews can reach layout marks faster and with fewer errors on complex or congested sites.
• Maintain centimetre accuracy under canopy: All-band L1, L2, L5, and L6 GNSS across 672 channels and IMU tilt compensation to 18 mm at 30 degrees help maintain a stable fix in challenging environments.
• Work through a full field day: Up to 16 hours of battery life, IP68 weatherproofing, and a magnesium alloy body rated to -40°C support demanding Canadian field conditions.

Overview and Who It's For

The Reach RS4 Pro is an all-band RTK GNSS receiver with integrated dual Full HD cameras, AR stakeout, and image-based point capture. It delivers 7 mm + 1 ppm horizontal RTK accuracy with IMU tilt compensation that initialises in under 5 seconds and requires no recalibration throughout the day, operating as a base or rover through LoRa, UHF radio, or NTRIP and controlled through Emlid Flow on iOS or Android.

This listing is for weekly rental. Contact Candrone to confirm availability and discuss base-and-rover configurations or multi-week rates.

• Surveying and Mapping: Topographic surveys, cadastral work, and stakeout where image capture and AR guidance reduce crew size and setup time on complex sites.
• Civil and Power: Construction layout, as-built verification, and cut and fill work where inaccessible or hazardous measurement points make traditional rod placement impractical.
• Mining and Aggregate: Ground control for photogrammetry and Lidar drone missions, volume checkpoints, and site control on active operations.
• Drone operators: Establish ground control points for aerial mapping missions across different verticals.

FAQs

What is the difference between the Reach RS4 and the Reach RS4 Pro?
The RS4 Pro adds dual Full HD cameras to the RS4 platform. This enables AR stakeout, overlaying your design onto the real world, and image-based measurement for capturing coordinates of points where physical rod placement is not possible. All accuracy specs, GNSS capabilities, battery life, and ruggedness are identical between the two models.

Can the RS4 Pro capture coordinates of points I cannot physically reach?
Yes. Using the built-in cameras and Emlid Flow, you can photograph inaccessible points across a road, above a pit, behind a fence, or along a building facade and calculate their coordinates directly from the images.

Can I use the RS4 Pro as a base station for drone GCP work?
Yes. The RS4 Pro operates as both base and rover. As a base, it streams RTCM3 corrections to a drone's remote controller through Emlid NTRIP Caster over internet or a local Wi-Fi network, making it compatible with most RTK-enabled drones including models from DJI and Autel.

Does the LoRa radio require a licence in Canada?
No. The 915 MHz LoRa radio operates licence-free in Canada under Industry Canada RSS-210. The UHF 450 MHz radio transmits up to 2 W and may require a licence depending on your application.

How do I set up a rental?
Contact Candrone to confirm availability, choose a rover-only or base-and-rover configuration, and arrange pickup or shipping. Multi-week rates are available on request.
