Product Introduction
INS300 is an autonomous navigation positioning and orientation system that is not affected by external environmental interference and has the capability of autonomous navigation positioning and orientation. It can be used in navigation guidance, attitude measurement, and control systems for missiles, ships, underwater robots, and underground engineering machinery vehicles. It is a key component of navigation control systems and is suitable for high-precision navigation control system applications.
INS300 can provide real-time information on the three-dimensional position, attitude, angular velocity, acceleration, and other aspects of the carrier. INS300 adopts high-precision fiber optic gyroscope as the core inertial measurement unit, with high accuracy, reliability and stability. The INS300 can accurately self locate the north for initial alignment, and can also introduce initial attitude information from the outside world for navigation data calculation.
INS300 supports external odometer information for assistance, and can also integrate satellite navigation information for data fusion. With the help of new generation precise calibration technology and multi-sensor data fusion technology, the reliability, accuracy, and dynamism of the system are greatly improved. The INS300 adopts the inertial navigation/satellite tight coupling algorithm and has functions such as dynamic base alignment, inertial navigation/satellite integrated navigation, autonomous zero velocity correction, and autonomous calibration.
