Surface Track Generator Application

2019 - 2020

ALTAY Information Technologies, Defense and Industrial Trade Inc.

This project is a desktop surface track generator application which will be used by Kongsberg Defense and Aerospace company in Norway for testing their related software. The purpose of this project to generate 200 surface track in maximum 30 milliseconds(2hz) and send this data over UDP to system under test machine. This data generated in real time for creating a surface track simulator.

This application can be used as a c++ library, and we add a QT interface for provided to user some settings such as sending wrong data. The biggest engineering problem is testing the sending time, which must not exceed 2hz. Because of that, we write a SUT application which can be tested and calculated the sending data time.

Tactical Data Link Management System

2018 - 2019

ALTAY Information Technologies, Defense and Industrial Trade Inc.

This project is a web application which can be managed in military networks such as link 11/11B, link 16, link 22 and jreap. The biggest engineering problem which I met in this project is why creating one hour simulation data take too much time such as 10 minutes and resolve this problem. It takes time to analyze it because creating simulation data has some integration such as Los, Route and Messaging analyzing. As a result, the whole structure has been changed and rewrote. With these changes, the time reduced from 10 minutes to one minute.
