Our SDI-PHINS Fiber Optic Gyro Compass Navigation System offers carrier's information, such as, true azimuth angle, motion attitude, heave, traveling velocity as well as 3D position. The position accuracy after calibration is better than 1 knot/hour(CEP). Inside SDI-PHINS, there are miniature and high accuracy fiber optic strap-down inertial integrated navigation system, which consists of miniature high accuracy triaxial FOG an high accuracy Q-Flex flexible accelerometer, high accuracy I/F conversion circuits, DC power supply, etc. By employing mature technologies, such as, digital temperature measurement, flexible PCB wiring, etc, Which enables our miniature design for our system with same volume and weight, SDI-PHINS's pure inertial measurement accuracy is better than OCTANS made by IXSEA. SDI-PHINS can be widely used in pure inertial fields of aviation, ships, vehicles, weapons in water, small size underwater vehicles and benchmark inertial navigation.
