TD-201 Fiber Optic Inertial/Satellite Integrated Navigation System

share

Introduction
TD-201 optical fiber integrated navigation system is a highly reliable and cost-effective optical fiber inertial/satellite integrated navigation system, which can be widely used in the navigation, control and measurement fields represented by high-precision vehicle, medium and long endurance UAV. TD-201 uses closed-loop fiber optic gyroscope (FOG) and high-precision accelerometer, combined with professional GNSS board and specially designed GNSS/INS data processing software (GINS), can provide accurate positioning information (longitude, latitude and altitude), attitude information (pitch, roll and heading), three-dimensional acceleration, angular velocity and other dynamic information. It is a high precision integrated navigation system.
The TD-201 series integrated navigation system can be configured with different hardware and software according to the needs of users. According to the characteristics of some navigation applications, the gyroscope can be replaced with a high-precision gyroscope, so as to meet the needs of different users to the greatest extent.
