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.
