The Teledyne CDL TOGS (Tiny Optical Gyro System) is a low cost FOG (Fibre Optic Gyro) based North seeking compass for use on vessels and Remotely Operated Vehicles (ROVs).
The extremely small size of the TOGS unit allows the system to be used in many underwater applications where space is at a premium. TOGS achieves 1% of full heading accuracy in less than 3 minutes and rapidly settles on its full heading accuracy of 0.5 deg secant (latitude) within 10 minutes. TOGS provides pitch, roll and heave outputs to accurately track all aspects of vessel or ROV motion.
Housing options include lightweight surface, 3000m subsea, 4000m subsea and 6000m Titanium. The 3000m version weighs only 7kg. Also available as an IMO Approved Surface Gyro (TOGS-S).
