Horizon MF Gyro Compass (HRG)
Maintenance-Free Compasses

Horizon MF is Raytheon Anschütz’ new maintenance-free gyro compass system. It uses so called Hemispherical Resonator Gyros (HRGs) to measure angular rates and accelerations in three axes. Based on these measurements sophisticated software algorithms compute heading but also roll and pitch.

Horizon MF comes as a maintenance-free (MF) sensor with an outstanding lifetime performance. Its Mean Time Between Failure (MTBF) value is more than 100,000 hours which is a multiple of the MTBF values of other solid-state compasses (such as FOGs) but also classical mechanical gyros bringing forth an outstanding long lifetime and long-term stability gyro compass for seagoing vessels.

Being designed as a modular system, Horizon MF can be extended to a heading management system by using an operator unit and a distribution unit. Anschütz Standard 22 gyro compasses, satellite compasses and magnetic compasses can be added.
