The object of the study are the measuring systems the distance between objects separated by an aqueous medium. The purpose of the work is the development of the equipment for determining the time of propagation of acoustic signals between objects in water based on the binding of "clocks" installed on the objects to a common time scale. Determination of the distance D from a dimension object (DM) to the multifunctional hydroacoustic station (MHAS) as part of the operational hydroacoustic measuring complex (OHMC) can be performed using the calculation method based on the measurement of propagation time τ of the acoustic signal between the DO and the MHAS. To measure the propagation time of the acoustic signal from the DO to the MHAS, the mutually synchronized clock is placed at the DO and the MHAS. The transmission time ti is counted according to the DO clock. The signal S(t), distributing in space, reaches the station's location point. The MHAS receives the signal, the detection time tj of this signal is fixed in accordance with the station's clock. The propagation time Δτ of the acoustic signal between the DO and the MHAS is determined by the station clock information about the transmission times from the DO to the MHAS. It is suggested to use Small Missile Ship – 23 (SMShip-23) the domestic equipment for time-frequency synchronization as a model generator. The use of SMShip equipment allows to refer the components of the LED equipment to the scale of the common time by recording the time of the start and the end of the measurement session by means of 13-byte data blocks, containing information about the offset magnitude of the internal time scale of the SMShip relatively to the absolute time scale, and the use of this information at the stage of processing the measurement data. Further on one can find the structural diagrams of the LED instrument components into the suggested includes modules of LED-MHAS, LED-DO, LED-K.
