Abstract

This paper presents the design and development of an electronic device with cellular and satellite coverage for localization and tracking of mobile assets in Colombia (public transport, freight, carriers, etc.). The development of this product integrates hardware, software and communication interfaces. It is aligned with a need identified in the market by the company One Solution Position: OSP LTDA. With this technology transfer we intend to improve the offer of wireless services for mobile asset tracking with a solution that covers the following features: dual operation (cellular/satellite), versatile, economical, low-power consumption, and based on international standards FCC and CE Mark.

Highlights

This paper presents the design and development of an electronic device with cellular and satellite coverage for localization and tracking of mobile assets in Colombia
Colombian telecommunications is a dynamic sector in continual growing of users and new services that offer multiple opportunities to the electronic engineering for the development of pertinent solutions for assets tracking and monitoring
It was identified that wireless communication market, in technological solutions for tracking and following mobile assets, offers GPRS transmission equipment with cellular coverage (Competitive National Politics, 2014)

Summary

Methodology

The design and development of an electronic device that allows satellite transmissions for tracking and following mobile assets will imply the precise knowledge of its relative location coordinates and the monitoring of variables of the mobile assets that are of interest for the final user, and that will be transmitted towards a register center for control, logistic, administration and auditory of the information. The electronic device pertinent to the needs of the user enterprises considered the development of hardware, communication interfaces and software for its performance in the operative stage that is shown in figure 2. This electronic engineering work had in mind the following market requirements: 1) Possibilities of universal coverage (it was implemented to reach national and regional coverage that comprehends Andean zone countries); 2) From the monitoring center, the continuous offering of regular location uploads of the mobile actives; 3) The GPRS modem will work with low frequencies respect from 3G and 4G technologies, which guarantees a low battery consume.
