ACOUSTIC UNDERWATER CONTROL SYSTEMS AUCS-M AND AUCS-L
The system AUCS is designed for control of underwater objects by transmission and reception of commands. 
The signals are communicated through a hydro-acoustic channel by selected combinations on the fixed frequencies.
The underwater control is carried out from the command unit to receivers connected or integrated in the underwater objects.
The AUCS consists of two main units:
- Command and Control unit, which contains:
- Electronic unit;
- Hydro-acoustic antenna (transmitter) with external power supply.
Option:
If the object (i.e. mine) is not equipped with hydro acoustic receiver, a separate receiver can be connected to the underwater object(s), which contains:
- Hydro-acoustic antenna (receiver);
- Amplifier/decoder.
Two versions of AUCS are available, ie. AUCS-M and AUCS-L.
