Abstract Context: This paper presents the design and development of an electronic device that operates as a satellite backup channel for automatic vehicle location (AVL) equipment, whose only communication channel is the cell network. Method: The design, manufacture and assembly of the hardware followed 4 phases and it was aligned with the IPC 2221 standard; this allowed improving the design experience and guarantees the correct electrical operation in the final product. Results: The information sent by the developed device corresponds to the data generated by the AVL device; this indicates that the information processing was designed correctly. In addition, it was possible to obtain a functional and versatile device, in which the blocks were correctly integrated; its firmware was designed to receive future updates that improved and expanded its capacity and compatibility with other devices. Conclusions: The final product, which works with the Iridium network, seeks to satisfy technological requirements of the freight transport sector in Colombia, with a low-cost solution, versatile and plug-and-play. The implementation of this type of technologies expands the capacity of tracking mobile assets, still in places where there is no cell network coverage. Keywords: AVL equipment, satellite backrest, Iridium network Acknowledgements: The authors thank the Colombian School of Engineering Julio Garavito for financing the study.
