SDR techniques to decode satellite beacons
| Resumo: | The advent of a new era of satellite communications brings with it a paradigm shift, a paradigm of reconfigurable receivers in software. Platforms like GNU Radio are therefore gaining preponderance. This revolution in these essential areas will allow for a more democratic area of communication in the future but will also act as a platform for more specialized study by users of this emerging technology. GNU Radio is an SDR platform that allows the construction of receivers for all types of receivers, with different types of modulations. In 2018, the QO-100 satellite was launched into a geostationary orbit. This satellite contains transponders that can be accessed by radio amateurs and other people and institutions. Of particular note are the beacons it has for communication with SSB modulation and a beacon for sending multimedia content. It was then suggested that a project be created in GNU Radio that could receive, demodulate and decode information transmitted by the QO-100 satellite, especially information coming from the SSB beacon and multimedia beacon. To receive the signal, an earth station was built, consisting of a coaxial cable antenna and Hack RF One, there is also an optional DX Patrol component. |
