Small satellite missions face two special challenges due to limited financial budgets. The first is tracking the satellite for orbit determination after orbit injection. The orbit can vary from the specified orbit when the satellite will be launched as secondary or parasitic payload. In case of unknown orbit parameters high-gain antennas cannot be pointed towards the satellite and establish the first connection needed for satellite activation. The second challenge is to transmit all housekeeping and scientific data to mission operations via a limited number of ground-stations. The Distributed Ground Station Network (DGSN) solution can solve the problem with permanent tracking and a faster orbital element provision to the satellite owners. And it can provide permanent reception of satellite signals with its data-dump mode in between main ground-stations provided by the satellite owner. The key feature is the network of small ground-stations placed globally connected via the internet and performing an automatic scan of satellite (and other beacon) signals, storing and sending them back to a central server, where they can be accessed by the satellite owner. With a correlation of the beacon signal and GNSS synched ground-station time the satellite position is determined with pseudo-ranging trilateration.
