Low gyro bias MEMS INS Inertial navigation system for Autonomous Driving
Product Description
The GI100C-B0 integrated navigation system consists of MEMS sensors and a high-end GNSS receiver board (NovAtel-718D), which is implemented through multi-sensor fusion and navigation solving algorithms. This product has high reliability and strong environmental adaptability. By matching different software, the product can be widely used in fields such as drones, unmanned vehicles, surveying and mapping, marine compasses, stable platforms, and underwater vehicles.
Main functions
The integrated navigation system utilizes GNSS receiver to receive satellite navigation information for combined navigation, outputting carrier's pitch, roll, heading, position, velocity, time, etc.After losing the signal, it outputs the position, velocity and attitude information of inertial solution, and has a certain navigation accuracy maintenance function in a short time. When combined with navigation, it can output the raw information that can be used for post-processing to be processed by the IE post-processing software of NovAtel.
