The paper considers the main tasks of autonomous unmanned underwater vehicles (AUV), lists the requirements for the onboard computing environment. Comparative analysis of central processing unit (CPU), graphics processing unit (GPU), field-programmable gate array (FPGA) and application-specific integrated circuit (ASIC) has been carried out. The FPGA was considered in more detail as the basis of the AUV onboard computing environment. The given example of designing a device that calculates an arithmetic function demonstrates the high performance of an FPGA and the complexity of developing a simple device in comparison with a similar task on a CPU.

The aim of the work is to develop a motion control system using an object-oriented programming approach. The objectives of the work are to build a mathematical model of the motion control system and develop an interface for user interaction with the program. The developed interface can be used as a simulation of the operation of surface vehicles, testing and debugging of the control system.

To ensure competitiveness with foreign enterprises, there is a need to reduce production time and cost of ship engineering products (SEP). This paper presents data of simulation for a repair process of SEP. The aim of researching is the justification of functional and simulation using for organizing the process of repair of SEP during required time and with cost reduction. The paper uses methodology of structural analysis in two types of notations. To obtain the quantitative result, the GPSS World environment is used. The results in the form of histograms of the processes of maintenance and repair of SEP confirm the effectiveness of proposed technologies.

The aim of the work is to determine the parameters of the mathematical model of the motion control system (MCS), which provides automatic monitoring of deep-sea communications with the minimum number of control devices of the MCS, due to which it is possible to use additional monitoring equipment. Mathematical models of the motion of an underwater robot are presented, block diagrams are constructed and the results of the motion of an underwater robot in the vertical and horizontal planes using the Matlab Simulink graphical simulation environment are obtained.
