Satellite Compass Spare Parts Suppliers
A satellite compass takes the ship's true heading from GNSS rather than from a spinning gyro or the earth's magnetic field. It uses two or more GNSS antennas a fixed distance apart and works out heading from the difference in the satellite signals reaching each one, which is why the antenna unit is the heart of the system and the part most spares questions come back to. Unlike the ship's gyro and magnetic compass, it has no moving parts to wear, and on multi-antenna units it also outputs pitch, roll, and rate of turn, so when it fails the fault is in the antenna, the cabling, or the processor rather than in a mechanism. Satellite compass spare parts suppliers carry those parts, matched to the maker and model fitted.
Antenna First, Then the Box
The system has few parts, and the antenna carries most of the risk because it sits outside:
- Antenna unit - the sealed dome holding the GNSS antennas and, in most units, the receiver electronics, exposed to sun and salt on deck.
- Antenna cable - the run from the dome to the display, whose connectors corrode and cause dropouts that read as a dead compass.
- Display and control unit - the screen and processor the crew reads heading from and the settings are held in.
- GNSS receiver boards - on units that keep the receiver below deck, the boards that resolve heading and position.
- Rate sensor module - the internal rate gyro or accelerometers that carry heading and attitude through brief GNSS dropouts, on the units that build one in.
- Backup battery - the cell that holds the settings and the almanac, so a flat one means a slow first fix and lost configuration.
Sourced to the Exact Unit
Satellite compasses come from makers such as Furuno, Hemisphere, KVH, JRC, and Simrad, and the parts do not cross between them, so the model decides the part. The antenna and its cable are the parts that decide whether the compass works at all, and because heading is derived from the antenna geometry, a replacement antenna is specified against the exact unit so the baseline and the alignment hold. Where a display or receiver is old and no longer supported, fitting a current unit and commissioning it through satellite compass services is often the better call than chasing a discontinued board.
The antenna and cabling are the parts most often replaced, so the satellite compass spare parts suppliers worth keeping on file stock those alongside the display and receiver parts behind them. The maker and model fix the exact part, since a used-equipment vendor and an OEM channel suit very different jobs.
