The FG105-A01 is a reliable, cost-effective fiber optic gyro strapdown inertial navigation system designed for UAVs, unmanned vehicles, ships, and aircraft navigation, control, and survey missions.
Featuring modular design, it integrates high-precision fiber optic gyros and FM accelerometers. The system fuses INS and GPS data via advanced filtering algorithms to estimate and compensate inertial errors, delivering accurate attitude, velocity, and position outputs. Custom vehicle motion constraints are available for land platforms to sustain long-term precise positioning.
Supporting flexible software function configurations including transfer alignment, integrated navigation, pure inertial calculation, and attitude-heading reference, this system can be customized to meet various industrial application demands.
