Building ultra-compact underwater navigation and communications systems, for applications where the smallest size and the lowest price are also critical as the accurate measurement and reliable data transmission, from idea to final product. My responsibilities are including but not limited to: electronic circuit design, 3D modeling (underwater housings, casting molds, etc.), assembling, testing, CNC machining and full-scale experiments.Built:⦁ The world smallest, as I know, hydroacoustic modem uWave (https://github.com/ucnl/Docs/blob/master/EN/Modems/uWAVE/uWAVE_Specification_en.pdf)⦁ LBL navigation system RedWAVE which provides simultaneous positioning of an unlimited number of objects even in shallow water (https://github.com/ucnl/Docs/tree/master/EN/RedWAVE)⦁ Compact USBL navigation system Zima (https://github.com/ucnl/Docs/blob/master/EN/Zima )⦁ Underwater acoustic modems (https://github.com/ucnl/Docs/tree/master/EN/Modems )⦁ Diver wireless communication system RedPhone fully integrated with USBL system Zima (https://github.com/ucnl/Docs/tree/master/EN/RedPhone).⦁ Navigation system Vostok for solving divers homing task (https://github.com/ucnl/Docs/tree/master/EN/Vostok )

Development (as a hardware designer) and experimental checks of communication and positioning system for divers and underwater acoustic video receiver and transmitter in close collaboration with the mechanical engineering team. Both systems were presented at IMDS-2015.

Development of acoustic communication hardware for fleet. Development of DAQ (Data Acquisition) boards.

Development, production and testing of TCXOs (temperature-compensated crystal oscillators). Рarticipation in the development of a TCXO Temperature Test and Calibration System. ⦁ Developed and was put into production a new series of temperature-compensated crystal oscillators (XO-225TC and XO-225)

Development and testing of crystal oscillators, build a prototype of a OCXO (Oven-controlled crystal oscillator).
