Accurate fluxgate compass heading data remains a fundamental parameter for marine navigation and the HSC100 marine compass uses fluxgate technology to deliver heading data for on board systems. Typical applications include enabling course up and true motion type displays on chart plotters, radar overlay onto electronic charts and stabilization of radars when used for MARPA/ARPA target tracking.

Integrated instrument systems can also benefit from having compass information. Allowing calculation of real time tidal set and drift when interfaced with a log and GPS. Most low cost heading sensors only output data at 1Hz (once per second) but the HSC100 outputs at 10Hz which is required for MARPA target tracking and accurate radar overlays (Part # ZDIGHSC100).
