Several military and commercial platforms are currently installing GPS and inertial navigation sensors concurrently with the introduction of high quality visual capabilities and digital mapping/imagery databases. This enables autonomous georegistration of sensor imagery using GPS/inertial position and attitude data. This georegistration capability enables data from digital mapping products to b...

This paper proposes the result of hardware in the loop simulation (HILS) for performance evaluation about a small attitude heading reference system (AHRS) based micro electro mechanical system (MEMS) suitable for small unmanned underwater vehicle. Unmanned underwater vehicles (UUV) have many applications in scientific, military, and commercial area due to its autonomy and the navigation system ...

Until recently the weight and size of inertial sensors has prohibited their use in domains such as human motion capture. Recent improvements in the performance of small and lightweight micromachined electromechanical systems (MEMS) inertial sensors have made the application of inertial techniques to such problems possible. This has resulted in an increased interest in the topic of inertial navi...

This paper introduces a water quality data measurement and analysis system equipped in underwater robot. The system consists of sonar navigation module, inertial navigation module equipped in underwater robot, data processing module and sensor detection module. Sonar navigation module and inertial navigation module equipped in underwater robot are separately used to detect current speed, azimut...

This paper presents the development of GPS based navigation system for portable devices at Tampere University of Technology. The objective was to develop a fully integrated system using MEMS inertial sensors with price range of US$ 10-15 for the set of inertial sensors combined with low-update rate GPS measurements. This system doesn’t require vehicle installation and can be easily transferred ...
