Resumen:
Initiatives to perform space-based radio astronomy below 30 MHz have emerged recently, since novel technological developments have increased their feasibility. The Orbiting Low-Frequency Antennas for Radio Astronomy (OLFAR) project, one of these initiatives, aims to use a swarm of nano-satellites to implement a radio interferometric array in space to observe celestial radiation with frequencies in the range of 0.3 MHz to 30 MHz. For its astronomical tasks, OLFAR requires that every satellite is able to establish a high-data-rate radio link with all the others. The inter-satellite communications subsystem of each satellite consists in a data distribution strategy, the coding, modulation and multiple access schemes and an antenna system, which is addressed in this work. The antenna system capacity requirements are influenced by the data rate generated by the astronomical observations, as well as …
