Product Introduction

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.
