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.

ZDIGHSC100T utilizes a new “Rate of Turn” version of the HSC100 that outputs the HDT and ROT messages required by a Class A transponder. For non-mandatory vessels, this therefore provides a simple low cost solution for adding heading and rate of turn to Class A transponders.
