Attitude Sensor. The TSS POS/MV (Position and Orientation Systems for Marine Vessels) is an inertial navigation system delivering full 6 degree-of-freedom position and orientation systems for ships. It combines data from an inertial unit made up of three acceleration meters and three gyrolasers (fibre optic gyroscopes) and two GPS antennas. It delivers the following data with a sampling frequency of 1-200 Hz: roll and pitch (accurate to 0.02°); heave (accurate to 5% amplitude); true heading (accurate to 0.1°). 1, record 3, English, - attitude%20sensor

Centrales d’attitude. La centrale TSS POS/MV(Position and Orientation Systems for Marine Vessels) désigne un système de navigation inertielle qui procure des solutions d’orientation et de positionnement à six degrés de liberté pour les navires. Elle combine les informations provenant d’une centrale inertielle constituée de trois accéléromètres et trois gyrolasers(gyroscopes à fibres optiques) et de deux antennes GPS. Elle délivre avec une fréquence d’échantillonnage 1-200 Hz les informations suivantes :roulis et tangage(précision 0. 02°) ;pilonnement(précision 5 % de l'amplitude) ;cap(précision 0. 1°). 6, record 3, French, - centrale%20d%26rsquo%3Battitude

Roll-rate gyro. The roll-rate gyro is less sensitive than the P [pitch] and Y [yaw] rate gyros. Roll-rate control limits fast roll rates during boost, before roll stabilization takes place.

The gyropilot, commonly called an automatic pilot (q.v.), consists basically of three devices, each of which detects disturbances of the aircraft in one plane and corrects for these disturbances by moving the appropriate control ...
