Horizon MF Maintenance-Free Gyro Compass (HRG) - 2

Maintenance-free Gyro Compass Technology With Horizon MF Raytheon Anschütz presents a new gyro compass based on strap-down technology. Strapped-down means that angular rate sensors (gyros) and accelerometers are not gimballed but mounted stationary in a housing. The sensors measure angular rates and accelerations in three axes. Based on these measurements heading but also roll and pitch is calculated. Strap-down technology is already well known and proven for many years – mainly in combination with fiber optical gyros (FOGs) or ring laser gyros (RLGs). Horizon MF uses so-called...
