In this article is presented a device hardware and software development in order to track and control any vehicle using Global Positioning System (GPS), Global System for Mobile Communications (GSM), General Packet Radio System (GPRS) and Wireless Fidelity networks (Wi-Fi). This development answer a real demand made by the national fleet & control management program from Transport Ministry (MITRANS), in order to be manufactured by the electronic group from the Industry Ministry (MINDUS); oriented to the creation of a new product to replace imports with technology independence & sovereignty. Hardware is conceived in a modular way with two electronic boards, one board as processing that exhibit an NXP i.MX6 UltraLite processor running Linux and the other one with specific components for these types of equipment including power supply. Software is an embedded C++ application, developed with Qt Creator multiplatform tool; to supervise and report, periodic and eventually, vehicle’s relevant data. Besides equipment´s internal data external data can be collected from I/O, RS232 and controller area network (CAN) bus. Data for their visualization and analysis could be sent in real time (active mode) and/or downloaded deferred (passive mode). Compliance with labs essays, attending to ISO 16750-2, and the successful introduction of first 3,000 units demonstrate validity of this development.
