Agent-based architectures supporting fault-tolerance in small satellites

Since the launch of the first artificial satellite in October 1957, both satellite computers and their onboard software have changed significantly to integrate more functionalities and making mission operations more reliable. As a result, satellites have become more sophisticated and mission designers have moved functionality from the ground...

Effects of Saturation for High-Throughput Satellite Buses

Bus saturation is deemed as one of the primary causes of delays in the data propagation between spacecraft components. However, the conditions under which bus congestion can affect measurements variability were not well characterized before. This paper presents a bus saturation model and a set of experiments to characterize the bus...

Cubesats to pocketqubes: Opportunities and challenges

<b>In the last two decades, CubeSats have changed the perception of satellite missions aided by standardization and usage of commercial-off-the-shelf components. CubeSats have also proven the feasibility of low cost and short development time space missions. The PocketQube with a form factor of 5x5x5 cm has been...
