Abstract: 1,162,714. Navigation. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 4 Nov., 1966 [6 Nov., 1965], No. 49637/66. Heading G4G. [Also in Division H4] An analogue computing arrangement processes signals from an acoustic system (see Division H4) for determining the position of a movable installation at sea relative to at least one beacon. In the Fig. 4 embodiment generator C controls the periodic emission of acoustic pulses into the water from the installation. The pulses are received by four beacons having their hydrophones anchored on the sea-bed at the corners of a square whose diagonals provide X-Y co-ordinate reference axes. The receipt of a pulse is signalled by transmission to the installation of a radio signal coded to identify the receiving beacon, and the coded signals are distinguished at the installation by receiver R. Bi-stable circuits b 1  to b 4  are all " reset " at the instant of acoustic emission and are subsequently " set " by respective output pulses from receiver R. The combined output of bi-stables b 1  and b 3  is a pulse whose duration and polarity indicate the difference #Tx between the times of receipt of an acoustic pulse by the two hydrophones on the X- axis. The pulse is passed to multiplier/integrator A 1  for conversion to a voltage proportional to the X- co-ordinate of the installation. A similar voltage for the Y co-ordinate is obtained from A 2 . The actual installation position and compass heading may be referenced to axes through a desired static position of the installation by further processing the X and Y voltages in a co-ordinate resolver Rs of known type.
