The system is featured as small size, light weight and high cost performance. NV-GI520 tightly integrated navigation system provides attitude information (such as horizontal attitude and heading), positioning information (such as longitude, latitude and altitude) and inertial measurement information (such as 3D acceleration and angular rate). The receiver is extendable with GLONASS. Its measurement accuracy and applicability can be further extended by assistant sensors such as odometer or barometric altimeter, etc. It can be widely appl
