Calibration-free
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 over 40 satellites simultaneously. These features ensure reliable performance and centimeter-level precision.
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.
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
Magnesium alloy body
The RS4’s magnesium alloy body is as strong as it is lightweight. This material is often used for aerospace equipment and high-end electronics. It strikes the perfect balance of durability and lightness, making it ideal for use in tough conditions while remaining easy to handle.
16 hours on one charge
The RS4 offers an impressive battery life of up to 16 hours on a single charge. Use the USB-C for recharging or use a power bank for even greater flexibility. Designed to keep working as hard as you do, without interruption.
Waterproof
Thanks to its IP68 rating, the RS4 is fully dustproof and waterproof. Whether it's raining, snowing or a dusty construction site, the Reach RS4 will keep working.
-40 to +65 ºС
The Reach RS4 operates in temperatures from -40°C to +65°C. Its performance remains excellent in both freezing cold and scorching heat.
