The ONWA KA-SC90 is a professional-grade Satellite Compass designed for high-stakes navigation where standard magnetic or electronic compasses fail. By using dual-antenna GPS carrier phase technology, it provides a stable heading that is immune to magnetic interference, vessel speed, or latitude—making it the gold standard for stabilizing radar and autopilots on commercial and high-end leisure vessels.
