UNI-GR2 RTK GNSS Receiver

It is the receiver that gives you a centimetre-accurate position in the field, on a pole with UNI-Collect for surveying and setting out, or on an excavator for machine control. Measure cables and pipes, set out from a drawing, check levels, and record as-builts.

In the open field 8 mm + 1 ppm horizontal and 15 mm + 1 ppm vertical with an RTK fix, and 3 mm + 1 ppm horizontal in static mode. Close to buildings or trees, where the sky view is limited, expect closer to 2 cm in real conditions.

1,408 channels across five systems: GPS, GLONASS, Galileo, BeiDou and QZSS. It gets a first fix in seconds and updates the position many times a second, which keeps it reliable on a busy site.

No. The built-in tilt sensor lets you survey with the pole tilted up to 45 degrees, so you reach points against a wall or in a trench without levelling.

Any NTRIP service. Use our UNI-RTK Premium network, or your own service such as SAPOS or FLEPOS, which are free and save you the € 1.000 a year that UNI-RTK Premium costs. The receiver can also act as a base station for other rovers.

Yes. We're happy to show you the system first with a no-obligation demo on location: at your job site, at your company, or at our office. When we deliver, we walk through it together so you can start right away. On-site training is available if you want it, but it's not a must: if you can use a smartphone, you can work with this. Think of it as extra certainty that you get everything out of it. And you can always call us.
