Coastal Safety Oceanic Navigation Using Non-GPS Digitised

The ODR (Object Dead Reckoning) system is useful in GPS denied environment such as inside buildings, tunnels, or dense forests especially in ocean navigation. Potential users of this system are military and security personnels as well as emergency responders. The ODR system uses a inertial measurement unit (IMU) attached to the object, ship or boat. The IMU provides rate of rotation and acceleration measurements that are used in real-time to estimate the location of the user relative to a known starting point. The ODR system works in both 2D and 3D-dimensional environments. Earlier systems used an impractically large IMU, where as, In the most recent version a much smaller IMU is being implemented. For navigation, the system would allow tracking the position of ship or boat in urban combat operations.
