Nowadays more and more attention is paid to the development of the unmanned devices that can be used in places where the work is dangerous or simply impossible to humans. One such area of rsearch is unmanned aerial vehicles (UAVs), which from military usage has grown into a wide variety of civil and scientific application areas.
UAVs are usually custom made devices in a particular area of use and their control systems are uniqe embedded computers. This custom hardware makes the development and prototyping a long and difficult process. To facilitate this process, the solution could be a unversal on-board computer, which is designed for prototyping and easy engineering telemetry systems.
The thesis is about the design of a modular telemetry system, and the selection of its useful nodes and components. Also an On-Board Computer (OBC) module was built, which is the main unit of the system. The goal was to develop a highly reliable, modular system that interfaces easily with task-specific sensors and other components.
The completed prototype has been tested during a high-altitude balloon application where system management tasks, direct module control and the resistance to environment conditions and reliability have been observed.
