The global navigation satellite system (GNSS) receiver iRTK5 makes it possible to determine a position almost anywhere in the world down to the centimetre. The system supports all signal space constellations as well as most radio protocols and provides full bandwidth support for mobile networks. An industry-typical innovative feature is its operation via an OLED colour touchscreen that also works in the rain. The housing is fashioned from a magnesium alloy, which is particularly light and corrosion-resistant.
