JT-GI3801 miniaturized MEMS based tightly integrated navigation system applies tight integration technology to combine the original carrier phase and pseudorange from 16-channel high-accuracy low-power L1 GPS receiver with MEMS Inertial Measurement Unit (IMU). The system is featured as small size, light weight, high performance and low cost.
JT-GI3801 tightly integrated navigation system provides attitude determination information (such as horizontal attitude and heading, etc.), positioning information (such as longitude, latitude and altitude, etc.) and inertial measurement information (such as 3D acceleration and angular rate, etc). Its measurement accuracy and applicability can be further extended by assistant sensors such as odometer and barometric altimeter etc. It can be widely applied in fields of UAV, transportation navigation, aviation and platform stabilization, etc.
