Introduction
The FSI400 Fiber-Optic Gyro-Inertial/Satellite Integrated
Navigation System is a highly reliable and cost-effective
navigation system suitable for a wide range of applications,
including navigation, control, and measurement in fields such as
aircraft, unmanned vehicles, unmanned boats, and drones.
The integrated navigation system adopts the modular design
philosophy of similar products, incorporating high-precision
closed-loop fiber optic gyroscopes (FOG) and high-precision
accelerometers, combined with high-performance GNSS boards. The
hardware circuitry is designed using an FPGA+DSP architecture.
Through multi-sensor fusion algorithms, GPS position and velocity
data are input into the filter, while INS position, velocity, and
attitude data are also used as filter inputs. The filter compares
the differences between the two sets of data to establish an error
model for estimating INS errors, and uses these errors to correct
the inertial navigation results, thereby obtaining the combined
navigation results for velocity, position, and attitude. The
inertial navigation system offers different configuration modes to
suit various platforms, such as airborne, vehicle-mounted, and
ship-mounted applications. When vehicle-mounted, vehicle
constraints are incorporated. Through error estimation and
correction, the system achieves long-term high-precision navigation
and positioning functionality for the platform.
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 items, 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.
