SGN-33P
Inertial Navigation System
SGN-33P is a high performance tactical grade Global Positioning System (GPS) aided navigation system. The MEMS inertial measurement unit and GNSS receiver provide highly accurate position, velocity and orientation values in static and dynamic conditions using advanced sensor fusion algorithms. With autonomous navigation filter initialization and dynamic initialization features, SGN-33P is designed to operate in a wide range of environmental conditions.
