Software to drive your entire workflow

The Reach RS4 comes with Emlid Flow, a comprehensive mobile and cloud solution compatible with both iOS and Android. It keeps your team aligned and your projects on track while supporting various site tasks.

 

Base and rover

NTRIP
Work in RTK with VRS or a single baseline CORS network in RTCM3 format. You can also connect another GNSS receiver as an NTRIP base using Emlid NTRIP Caster

Dual-band radio
UHF 450 MHz:
  • Transmit and receive
  • Up to 2W (may require a license)
  • Compatible with Reach and 3rd-party receivers with TRIMTALK 450S support
LoRa 915 MHz:
  • Transmit and receive
  • Up to 1W (license-free in North America)
  • Compatible with Reach receivers
Quick release mount

This mount is specifically designed for tilt compensation, eliminating backlash and securing the receiver firmly to the survey pole. Even a small amount of wobble between the device and the pole can compromise the accuracy when tilting. The quick-release system provides a fast and reliable connection for maximum precision.

 

Next-gen tilt compensation

The Reach RS4 delivers accurate results even at high tilt angles — for example, a 30° tilt still achieves 18 mm precision.1 The compensation mechanism activates with just a few moves and remains stable throughout the survey, saving time and avoiding the need for recalibration.
