Reach RS3 RTK GNSS Receiver
Survey-grade accuracy with tilt compensation up to 60°
Overview
The Reach RS3 is a versatile RTK GNSS receiver featuring advanced tilt compensation technology. It functions seamlessly as both a base and rover with dual-band radio or NTRIP connectivity, delivering survey-grade precision in RTK, PPK, and PPP applications.
Centimeter Accuracy Even at 60° Tilt
The Reach RS3's IMU-based tilt compensation technology enables precise measurements at angles up to 60 degrees with an accuracy of 20mm. The system continuously measures and corrects tilt in real time, keeping you on target without requiring constant leveling.
Key Advantages
Effortless and Robust IMU Tilt Compensation
Calibration-Free Operation
We calibrate each unit individually at the factory, so you can get your Reach RS3 up and running right out of the box without additional setup procedures.
Immune to Magnetic Disturbances
Unaffected by magnetic fields, the RS3 provides robust tilt compensation even when working close to metal structures or in challenging electromagnetic environments.
Quick Initialization
Tilt initialization takes about 20 meters of walking or 10-20 seconds of tilting. The system is typically ready by the time you walk from your vehicle to the survey point.
Rapid and Reliable GNSS Performance
Reach RS3 achieves centimeter-accurate solutions in about 5 seconds. It maintains robust performance even when the sky view is partially obstructed, or the receiver itself is tilted.
RINEX Logging and PPP Support
Record raw data in the RINEX format for post-processing. You can use our free PPK software, Emlid Studio, or any other software that supports RINEX. Logs are also compatible with OPUS, AUSPOS, and PPP services, enabling highly accurate results anywhere in the world.
16 GB storage provides 160+ days of logging at 1 Hz.
Extended Battery Life
Reach RS3 comes equipped with a built-in, industrial-grade battery that can endure up to 22 hours of logging or 18 hours of working with tilt in RTK. For uninterrupted multi-day operation, simply connect a power bank via the USB-C port, just like you would with your mobile phone.
Flexible Connectivity Options
Built-in LTE Modem
Insert a SIM card into your Reach RS3 and let it broadcast or receive corrections via NTRIP, providing internet-based correction capabilities wherever cellular coverage is available.
Get Corrections from Multiple Sources
Connect to CORS networks, other Reach receivers, or third-party base stations for maximum flexibility in your surveying workflow.
