PURPOSE:To calculate and indicate an actual inclination of the submarine line depending on the distance in the horizontal direction and changes in the depth by detecting the movement of own ship at each transmission cycle of a detecting pulse. CONSTITUTION:Data such as row address from a Y axis (timewise) counter 6, a line address from a latch circuit 22 corresponding to sea bottom depth at the row address, the depth equivalent to 1 address linewise from an ROM32, the navigation range from an ROM34 and set row address data from a marker setting circuit 24 are introduced into an input buffer 23 and a computation is performed as specified with a CPU35 and a ROM36. The inclination value thus obtained is sent out from an output buffer 25 and indicated on an inclination display 38. |
