RTK-grade auto-steering with no base station — powered by PPP and a proprietary in-house GNSS engine. Australian-engineered, globally deployed.
Trusted by operators across 50+ countries
A single IP67-sealed unit — GNSS receiver, IMU, 4G modem, Wi-Fi and internal radio — factory-integrated and field-ready.
GPS L1/L2/L5, GLONASS, BeiDou B1/B2/B3 (incl. BDS-3), Galileo E1/E5a/E5b and QZSS — full-sky coverage for reliable RTK in any condition.
Sub-3cm accuracy globally via satellite-delivered corrections. 3-minute convergence, 99.99% signal stability, zero CORS dependency — anywhere on Earth.
6-axis MEMS IMU at 100Hz. Roll/pitch <0.2° RMS, heading <0.3° RMS. Automatic slope compensation and attitude output included.
Multi-band 4G LTE plus a 410–470MHz internal radio (LoRa & GFSK/4FSK). TrimTalk450, TrimMark 3, South and Satel — works where cellular doesn't.
802.11b/g/n/ac Wi-Fi and Bluetooth 4.1 for wireless configuration and real-time streaming. No dedicated display required.
Engineered for Australia's outback heat, Brazil's wet seasons and Kazakhstan's winters. Fully sealed against dust and immersion.
No separate receiver, modem box or radio to wire up. NavOpen integrates the full positioning stack into one rugged housing that mounts to virtually any machine roof.
Satellite-delivered corrections give you centimetre accuracy without towers, subscriptions to local CORS networks, or a second radio in the paddock.
NavOpen now works with AgOpenGPS — a streamlined auto-steer build for farming. Three things get your tractor steering itself. No build weekend required.
Our proprietary RTK engine and IMU fusion run PPP and RTK at the same time. When NTRIP connectivity drops, you don't lose accuracy — L-band PPP corrections hold centimetre-level precision while cellular service is restored.
It's a capability unmatched by F9P and UM982 — and by many receivers that cost significantly more.
Which is more likely to fail — your phone signal, or your tree line?

Straight A–B lines and controlled-traffic farming across thousands of hectares with repeatable centimetre accuracy.
Grain · Cotton
Tight, repeatable rows under canopy where signal is challenging — IMU-aided steering holds the line.
Tree crops · Vines
Machine guidance for earthworks and site prep — no local base, no survey crew waiting on corrections.
Earthworks · SurveyOne of only five companies worldwide with a proprietary RTK engine — alongside Trimble, Leica/Hexagon, Topcon and NovAtel. No rebadged chipsets.
