Abstract
The demand for satellites and space systems with ever-increasing avionics requirements is constantly growing, whether in the field of satellite communications or earth observation. Traditional architectures for Data Handling Systems (DHS) on satellites are reaching their limits in terms of flexibility, interoperability and reusability, while slowing down the innovation cycle due to costly qualification. With regard to commercial and industrial solutions, it is evident that ‘plug and play’-like systems based on open standards can overcome the above-mentioned disadvantages. For this reason, this paper describes how open standards could affect the architecture of future satellite DHSs. In particular it shows an transition path from the traditional federated architecture to a centralized but modular architecture based on adapted industrial standards.
