GPS/INS close combination system NV-GI120

The NV-GI120 inertial navigation system uses tightly-coupled technology to tightly combine high-precision, professional-grade, 16-channel dual-band dual-antenna GPS receivers with MEMS inertial measurement units, featuring small size, light weight, and high performance-to-price ratio.
The navigation system can provide three-dimensional acceleration, angular velocity, attitude, and heading orientation and positioning information, and can further improve the accuracy of the system by extending auxiliary sensors such as odometer and altimeter for different application environments. The navigation system can be widely applied to drones, vehicle navigation, Aviation and platform stability control and other fields.
