PURPOSE: A navigation data storage system for a ship is provided to supply various information about an accident regardless of sinking by storing various data in a plurality of auxiliary VDRs. CONSTITUTION: A main VDR(10) is comprised of a camera(1), a video board(2), an input and output interface(5), an engine control data memory(8), and a microcontroller(9). The video board stores the image signal of the camera in an image data memory. The engine control data memory stores the data about the engine of a ship. An auxiliary VDR(30) is attached to the front, rear, lateral, upper and lower sides of the ship. A solenoid for escape is operated for releasing a latch. A water pressure sensor senses a floating point. An antenna driving motor transmits a structure electric wave. GPS data is provided from the main VDR. The GPS data memory stores the engine control data and the image data. |
