This paper depicts the global specifications and the successful results for a cost-effective system developed for training purposes in the small satellite technology field. The didactic satellite subsystems were fully designed, manufactured and tested at the Institute of Engineering UNAM. Information about intelligent subsystems for the portable didactic satellite (PDS), its operations software as well as successful results obtained in laboratory operations for the first PDS prototype are exposed in this paper. Keywords: didactic satellite, operational prototype, portable laboratory equipment, training system, cost-effective technology. 1 Introduction Mexico has developed in the past a couple of small satellites projects, and currently is developing a couple more of them. Those projects are very important not only to stretch the enormous technological gap with industrialized countries, but also to launch a domestic satellite development and research program associated to the future Mexican Space Agency. The last could take us in the medium and long term to generate our own Remote Sensing and Communications satellites, according to the needs of the country. However, to conduct such a line of work, it is required the formation, qualification, and training of human resources in these technological areas. According with our experience, the development of an experimental satellite in our country requires of 4 to 8 years of work, depending on the obtained financial support, as well as on the magnitude of the technological and scientific objectives. Figure 1. Developed Mexican PDS showing its architecture based in subsystem modularity. We have also detected that this type of projects allows the participation of 25 to 200 people according to the challenges and magnitude of the technological demands aimed by the satellite mission. Considering the cost of this type of projects (half million to 5 million US dollars) the relation between the amount of participant personnel versus project cost is very low. In addition, if we consider how the young Mexican University people becomes attracted and motivated by satellite and space projects, it is observed an extremely low efficiency in the rows of participation and formation of new human resources in this field. By the way, this technology arena is related with the possibility to generate alternative solutions to national security problems from our country. The exposed scenario took us to the PDS development. In this way, our group has successfully developed a cost-effective training system in small satellite technology employing commercial-off-the-shelf (COTS) parts as well as electronic components from the automotive and services
