Abstract
A hybrid inertial navigation system and method are provided. The system includes a conventional inertial measurement unit (with a three-axis accelerometer and a three-axis gyroscope operating at a high data rate and low sensitivity), light pulse atom interferometer accelerometer and gyroscope (operating at a low data rate and high sensitivity), and a processing system. The method of the hybrid inertial navigation system includes precisely determining an acceleration and an angular velocity and allowing light pulse atom interferometry operation under dynamic environments. A processing system of the hybrid inertial navigation system performs feedforward correction operations on the light-pulse atom interferometer accelerometer and gyroscope of the hybrid inertial navigation system. The processing system determines one or more control signals based on the inertial information from the conventional inertial measurement unit, a light pulse atom interferometer model, and the feedforward algorithm.
