Introduction
The FSI301 Fiber Optic Integrated Navigation System is a highly reliable, cost-effective fiber optic inertial/satellite integrated navigation system that can be widely used in navigation, control, and measurement fields, such as high-precision vehicle-mounted systems and medium-to-long endurance unmanned aerial vehicles (UAVs).
The system employs closed-loop fiber optic gyroscopes (FOG) and high-precision accelerometers, combined with professional-grade GNSS boards, and processes data through specially designed GNSS/INS data fusion software (GINS) to provide precise positioning information (longitude, latitude, and altitude), attitude information (pitch, roll, and heading), as well as three-dimensional acceleration, angular velocity, and other dynamic information, making it a medium to high-precision integrated navigation system.
The series of integrated navigation systems can be customized with different hardware and software configurations to meet user requirements. For specific navigation applications, the gyroscope can be replaced with a high-precision gyroscope to maximize flexibility and meet diverse user needs.
Technical Specification
The integrated navigation system integrates high-precision fiber optic gyroscopes and accelerometers within an independent structure. The gyroscopes and accelerometers selected for the system represent the leading level of process inertial components in the industry. The system has undergone full temperature parameter compensation for zero position, scale factor, non-orthogonal error, and acceleration-related terms, enabling it to maintain high measurement accuracy over extended periods.
The series of integrated navigation systems can be customized with different hardware and software configurations to meet user requirements. For specific navigation applications, the gyroscope can be replaced with a high-precision gyroscope to maximize flexibility and meet the diverse needs of different users.
