Airborne Fiber Optic Inertial Navigation

The strapdown inertial navigation system is characterized by autonomy, concealment and complete acquisition of carrier motion information. It has become an indispensable navigation tool in military fields such as missiles and combat vehicles, industrial fields such as mining and exploration, as well as civilian fields such as unmanned vehicles and Marine cruise ships.

Introduction of Fiber Optic Gyroscope

Fiber optic gyroscope is a sensitive element based on optical fiber coils. The light emitted from the laser diode propagates in two directions along the optical fiber. The difference of light propagation path determines the angular displacement of the sensitive element.

MEMS inertial measurement unit

ERDI LASER LTD’s MEMS inertial measurement unit adopts the same batch of low-cost MEMS chips, uses multi-sensor fusion algorithm to build MEMS array navigation system information processing system, and corrects the installation errors and sensor errors in real time during task execution by online calibration technology.

Doppler Laser Anemometry

The wind-measuring lidar emits laser, which points to the detected area with the azimuth set by the system. Due to the movement of aerosol particles under the action of wind field, Doppler shift occurs in the atmospheric echo signal, and radial wind speed is measured through its Doppler shift.

Fiber optic gyro space application technology

Interference Fiber Optic Gyroscopes (IFOGs) are angular velocity inertial sensitive devices based on the Sagnac effect, which have become the main choice for spacecraft inertial navigation and attitude orbit control with their advantages of all-solid-state, irradiation resistance, low energy consumption, high dynamics, and long lifetime.

Power supply design for erbium glass laser rangefinder

The overall scheme and detailed circuit design were completed by comparing three pulsed constant-current drive schemes and establishing the technical path of energy storage network with switching circuit for the Erbium glass laser rangefinder. The experimental results show that the drive power supply can output pulse current with pulse width from 2.3 ms to 2.5 ms, size from 12 A to 14 A, and repetition frequency from 10 Hz, with good current stability and no overshoot, and has the advantages of high reliability, small size, light weight and full protection function, which can meet the system requirements.
