Space-based radar sensors have transformed Earth observation since their first use by
Seasat in 1978. Radar instruments are less affected by daylight or weather conditions than …

The assembly of 3D printed composites has a wide range of applications for ground
preparation of space systems, in-orbit manufacturing, or even in-situ resource utilisation on …

Future autonomous transportation is one of the most demanding application areas in terms
of connectivity, as it has to simultaneously meet stringent criteria that do not typically go …

The phasing parameter F determines the relative phasing between satellites in different
orbital planes and thereby affects the relative position of the satellites in a constellation. The …

Collaboration between multiple super-agile satellites with dynamic imaging capabilities
provides an opportunity for highly efficient observation of large-area targets. Reasonable …

Earth observation satellite (EOS) systems often encounter emergency observation tasks
oriented to sudden disasters (eg, earthquake, tsunami, and mud-rock flow). However, EOS …

This work focuses on the study of the reconfiguration strategies available for uniformly
distributed satellite constellations and slotting architectures. Particularly, this paper deals …

Data collection by satellites during and after a natural disaster is of great significance. In this
work, a reconfigurable satellite constellation is designed for disaster monitoring, and …

A group of satellites, with either homogeneous or heterogeneous orbital characteristics
and/or hardware specifications, can undertake a reconfiguration process due to variations in …

The optimal design of a satellite constellation is a highly constrained, multidisciplinary
problem. The satellite constellation requires a flexible optimal deployment algorithm that can …
