New Acta Astronautica paper on active debris removal service for large constellations is out!

How can we guarantee the long-term sustainability of the constellation? One of the solution is represented by the development of active debris removal and servicing activities for the constellation fleet.
The new paper published in Acta Astronautica by @Giacomo Borelli, @Gabriella Gaias, @Camilla Colombo presents a design of the rendezvous and proximity operations required for an active debris removal service for large constellation.

A new analytical model to evaluate collision probability with large satellite constellations

In a space environment with an ever-growing satellite population, the latest paper by Eduardo Polli, Juan Luis Gonzalo and Camilla Colombo eases studies in the context of Space Situational Awareness, by developing an algorithm capable of assessing the average collision probability between an object subjected to continuous tangential thrust, and tens of thousands of constellations’ satellites, all within milli-seconds. Available here.

From Italy to CyberSpace: COMPASS joins the 71 International Astronautical Congress

In-person meetings have become a rare luxury due to the COVID-19 pandemic. That is why the International Astronautical Federation has made the 71st International Astronautical Congress – The CyberSpace Edition their first fully online congress. On 12-14 October more than 10,000 attendees joined all over the world to share the latest space developments. The COMPASS team contributed with 5 papers and videolectures.

10th International Workshop on Satellite Constellations and Formation Flying

From 17 to 19 July, our Gabriella Gaias and Simeng Huang attended the 10th International Workshop on Satellite Constellations and Formation Flying, hosted at the University of Strathclyde, Glasgow, UK. Gabriella presented a new tool for spaceborne navigation systems based only on angular observations, and Simeng proposed an efficient strategy for the de-orbiting of large constellations.
