Description
Unmatched precision, even under canopies and in canyons
The Reach RS4 can track all available satellite constellations and frequencies, including the lower L5 and L6 bands, which are more resistant to multipath and interference. With 672 channels, it can track 40+ satellites at a time. These features ensure reliable performance and centimetre-level precision.
Next-gen tilt compensation
The advanced tilt compensation stays accurate even at steep angles. For example, at a 30° tilt, the Reach RS4 Pro still delivers 18 mm precision. Initialisation takes just a few movements and remains stable throughout the job—no manual recalibration needed.
Quick release mount
The custom-designed quick release mount ensures the receiver is locked firmly to your survey pole, eliminating backlash. Even the smallest wobble can affect tilt-based measurements at steeper angles. This mount solves the issue with a fast and rock-solid connection for reliable data accuracy.
Base and rover connectivity
Connect to VRS or single-base CORS networks using RTCM3 format for precise RTK corrections. You can also transmit corrections from your own base using Emlid NTRIP Caster
