Problem
-- Existing software components needed to be tested to ensure - that requirements were being met. -

-- My job was to translate software component requirements into - Model-in-Loop unit tests in Simulink. -
-Result
-- Created Model-in-Loop test cases for ~50 requirements using - Simulink test. I was able to identify and resolve 7 issues at the model - level to prevent them from reaching in-vehicle testing. To - improve testing, I created a script to automatically run all - test cases and generate a report for easy identification of - issues. Also created documentation in - Confluence - to streamline future test case generation. -

Problem
-- Hughes mobile terminals allow customers to have internet and - phone access in remote areas via a satellite connection. - Some customers may find value in a GPS feature built into - the terminal. In this situation, the terminal would send GPS - coordinates to a server at regular intervals of time, - distance, and/or velocity as configured by the end-user. -
-Task
-- My task was to investigate a way to minimize the data packet - size of GPS coordinates and to update the terminal's - software to send these data packets to a server configured - by the end-user. -
-Result
-- This project was assigned to me after the completion of my - previous project, which was intended to last the entire - internship. I was able to determine that - MQTT-SN - was a good option as it simply sends a data packet to a - server without checking for acknowledgement and the packet - header is sufficiently small. I successfully implemented the - packet structure and delivery to the server on the terminal - software written in C. However, I was unable to get the - server to recognize that it received the packet in my - remaining time at Hughes.
