ERICCO INERTIAL TECHNOLOGY ER-FINS-70 High Performance & Low Cost FOG INS 1. Introduction ER-FINS-70 High Performance & Low Cost FOG INS mainly composed of three solid fiber optic gyroscopes, three quartz flexible accelerometers, data packing plates, body structural parts and related software. It measures the angular velocity and linear acceleration of the carrier motion; performs the error compensation of temperature, installation misalignment angle, non-linearity and zero position etc.; automatically searches and outputs true north heading; provides three-dimensional attitude; provides information for carrier attitude and navigation control and the measurement result is output through RS422 serial interface. 2. System Structure and Functions The system consists of a chassis, an IMU body (with a three-axis fiber optic gyroscope, a three-axis accelerometer), a gyro motherboard, a metered motherboard, a secondary power supply, a navigation computer, and connectors. It can meet the requirements of all-weather full-autonomous three-axis attitude measurement of the carrier and has self-alignment function. It can realize short-term pure inertial navigation and combined navigation functions, and output carrier real-time attitude data. 3.
