Sdr-server is a project designed to provide access for multiple users to a single rtl-sdr stick. This allows running several concurrent observations within 2Mhz bandwidth of rtl-sdr. This turned out to be a very useful feature for satellite communications. Many cubesats transmit data on a very close frequencies, which allow communication with several satellites at once. This feature is widely...

With the increasing number of satellites launched into space, it has become essential to anticipate disastrous space events and formulate effective policies based on the observations. As part of the Google Summer of Code program 2021, we developed a set of event detectors under the two-body problem by implementing orbital mechanics algorithms from the literature. We developed a point-by-point...

Despite the CubeSat industry becoming increasingly dominant within the space sector, it falls behind in one critical section: Cryptography. Current CubeSat security issues are often underestimated or neglected, despite the existing CCSDS standards for (all) satellite telecommunication. This is due to the fact that current CubeSat implementations simply do not require such strict security...

Computing a link budget allows to determinate the possibility to communicate with a satellite. This is done by accounting for all the power gains and power losses encountered by a signal along its transmission path. Due to the numerous amount of such gains and losses, computing a link budget can prove to be a difficult and tedious task, especially to students and newcomers.
