Emlid Reach RS4 Weekly Rental

Emlid Reach RS4 brings all-band RTK GNSS and IMU tilt compensation to professional survey and construction workflows, enabling field teams to capture centimetre-accurate points quickly across a full workday without interruption.

• Maintain centimetre accuracy under canopy: All-band L1, L2, L5, and L6 GNSS across 672 channels tracks 40+ satellites simultaneously for stable positioning in forests, urban canyons, and near reflective structures.
• Measure without re-levelling the rod: IMU tilt compensation initialises in under 5 seconds and maintains accuracy to 18 mm at 30 degrees for capturing corners, ditch bottoms, and fence lines.
• Operate as a base or rover: Dual-band LoRa and UHF radio lets the RS4 serve as a base station for drone GCP work or as a rover receiving network corrections without additional hardware.
• Work through Canadian field conditions: A magnesium alloy body, IP68 protection, up to 16 hours of RTK operation, and a -40°C to +65°C operating range support demanding field environments.

Overview and Who It's For

The Reach RS4 is an all-band RTK GNSS receiver with IMU tilt compensation, dual-band radio, and 672-channel GNSS tracking. It delivers 7 mm + 1 ppm horizontal accuracy and operates as both base and rover through LoRa, UHF, or NTRIP, with Emlid Flow supporting topographic survey, stakeout, RINEX logging for PPK, and drone base-station workflows.

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, boundary work, and construction stakeout where fast tilt compensation and all-band tracking reduce setup time in challenging environments.
• Civil and Power: As-built documentation, cut and fill, and layout work on active construction sites where crew efficiency and reliable GNSS performance under obstructions matter.
• Mining and Aggregate: Ground control points for drone photogrammetry and Lidar missions, volume verification, and site control across open-pit and aggregate 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, enabling AR stakeout and image-based measurement of inaccessible points. All accuracy specifications, GNSS capabilities, radio options, battery life, and ruggedness are identical between the two models.

Can I use the RS4 as a base station for drone GCP work?
Yes. The RS4 operates as both base and rover. As a base, it streams RTCM3 corrections through Emlid NTRIP Caster over internet or local Wi-Fi and also supports UHF radio correction links for areas without cellular coverage.

Can I log RINEX data for PPK post-processing?
Yes. The RS4 logs raw GNSS data in RINEX format to its 16 GB internal storage, supporting PPK workflows where real-time RTK correction is unavailable or independent accuracy verification is required.

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.
