In the complex and ever-changing fields of industry and research, the accuracy and reliability of navigation systems directly determine the success or failure of tasks. The IF3900 series high-precision fiber optic inertial navigation system launched by Micro-Magic Inc., with its groundbreaking technical design and exceptional performance, delivers innovative solutions for premium application scenarios including aerospace, autonomous driving, marine exploration, and UAV navigation.
The IF3900 series products are equipped with high-precision closed-loop fiber optic gyroscopes and high-precision quartz accelerometers, and use multi-sensor data fusion technology to combine inertial measurement with GNSS, achieving long-term high-precision integrated navigation. At the same time, IF3900 has post-processing capabilities, which can improve the heading, attitude, and position accuracy of the product through post-processing software.
The IF3900 series products are equipped with high-precision closed-loop fiber optic gyroscopes with zero bias stability of 0.001°/h, achieving extremely low drift in all temperature environments to ensure long-term stability of attitude and heading; The built-in high-precision quartz accelerometer has a zero bias stability of up to 10μg, which can accurately sense the motion of the carrier, with no delay in dynamic response, suitable for high-speed and high maneuverability scenarios; At the same time, by integrating multi-sensor fusion technology and combining GNSS with inertial measurement data, even if satellite signals are temporarily lost, centimeter level positioning accuracy can still be maintained through pure inertial navigation.
Supporting differential reference stations and post-processing software, the heading accuracy can reach 0.002° (RMS) through algorithm optimization, and the position accuracy can be improved to RTK 2cm+1ppm, meeting the high requirements for data backtracking in scientific surveying, geological exploration, and other fields.
Supports single/dual antenna mode, multi protocol output (RS232/RS422/CAN/Ethernet/USB), with a data update rate of up to 800Hz, compatible with Novatel post-processing software, and easy integration with existing systems. By intelligently compensating for lever arm errors, the offset between GNSS antenna and inertial navigation center can be calibrated with just one click, ensuring data consistency in complex installation scenarios.
Through comprehensive vibration testing, covering 20~2000Hz wideband random vibration, multi axis composite sweep frequency, and transient impact (half sine wave 11ms/30g), the overall structural stability and functional integrity of the system under extreme mechanical environments have been verified. Through vibration temperature electromagnetic multiphysics coupling testing, the system is still able to converge quickly, demonstrating its ability to quickly recover under strong disturbance conditions.
