A PocketQube type satellite development is in progress in the Budapest University of Technology and Economics. The university's more facultys, departments and external experts are working on the SMOG-1 project, and their goal is to turn out as a success, like the Masat-1. The primary mission of the satellite to measure the electroagnetic smog around the Earth, in the frequency band of the DVB-T system. The terrestrial digital video broadcasting is using this 470 MHz - 860 MHz band, and the power that reaches the space, is lost. This task has more challenges, like this type of measure has been never done before, and no satellite with this size has been operated int the sapce.

My thesis is to design and create a small receiver that was optimized to receive the signals of the SMOG-1, and create an antenna for this function. This task contains a electronic level and circuit level design, planting, and software developing. The receiver convert the radio frequency signal to digital data, so we can see the packets as a hexa string, with the help of an USB connector and the serial ports of a personal computer.

This receiver's other purpose to popularize the SMOG-1 project. If they can be the part of this historical moment, mybe this will bring them closer to the spacesciences, the BME and the Faculty of Electrical Engineering and Informatics. Hopefully more people will know about this team, and in the future more sponsor can support the projects. This requires to lower the cost of the receiver and the antenna, so it can be produced in higher numbers. Beacuse of this, I have aimed the simplicity, the cost-effiency and the reusability.
