— RUG-4 GNSS Receivers
One Enclosure.
Four GNSS Receivers.
Every RUG-4 shares the same rugged aluminium enclosure, the same IMX-6 tactical-grade IMU, and the same RS232 / RS485 / CAN interfaces. They differ only by GNSS receiver — which determines RTK accuracy, heading precision, update rate and anti-jam protection. This page compares all four side by side.

— How to read these figures
* GPX-1 RTK accuracy is a fixed CEP specification with no published ppm / baseline-distance term, unlike the other three (fixed error + ppm-of-baseline). GPX-1 time-to-fix is vendor-published per fix type — 3D, RTK and heading — from cold start; the other vendors publish 3D cold-start time separately from RTK convergence, which is measured once a 3D fix and corrections are already established. The two are not directly comparable on a cold-start basis.
Figures are typical / RMS values taken from each manufacturer's published datasheet, not independent testing.
