How a marine satellite compass works
Two GNSS antennas provide a geometric heading that does not depend on the local magnetic field. An inertial unit fills in the vessel dynamics, allowing GeoX to calculate heading, roll, pitch, heave and rate of turn even during demanding manoeuvres.
What GeoX improves
Radar
Fast, stable heading supports overlay and echo alignment.
Sonar
Roll, pitch and heave describe the motion affecting depth.
Autopilot
Heading and rate of turn support timely steering corrections.
Bathymetry
RTK position and attitude improve georeferencing consistency.
Core architecture
| Function | Hannon GeoX | Purpose |
|---|---|---|
| Heading | Dual GNSS antennas + inertial fusion | True heading independent of local magnetism |
| Position | Multi-band L1/L2/L5 multi-constellation GNSS | Fast positioning with RTK support |
| Attitude | Internal calculation up to 400 Hz | Roll, pitch and heave tracking |
| Outputs | N2K, NMEA 0183 / High Speed Serial, CAN, BLE | Integration with marine and software systems |
| Logging | Embedded Blackbox | Record and replay navigation data |
NMEA 2000 and navigation software integration
GeoX publishes vessel heading, rate of turn, attitude, heave, rapid position, COG/SOG and GNSS quality information. Output rates are selectable so the installation can balance consumer needs and network load.
Who it is for
GeoX is designed for technically equipped leisure craft, fishing boats, marine integrators, bathymetry and professional projects where several systems need the same trustworthy reference.
