This seminar will describe the general problem around the increase of population of space debris and of active satellites, which is suffering an exponential growth due to the deployment of mega-constellations and cube-sats.

The seminar will focus on how this problem is being tackled from the point of view of detecting all those objects and estimating their orbits, this is, the objects catalogue build-up and maintenance process based on observations obtained from on-ground and on-board sensors such as radars and telescopes.

This process includes aspects such as including observation correlation, orbit determination, manoeuvre detection and covariance realism, all of which will be covered from the point of view of past, current, and future challenges.

Maintaining such a catalogue of objects is a crucial backbone for the Space Traffic Management policies and capabilities currently being defined in Europe and worldwide.

Speaker:

Diego Escobar holds a PhD in Aerospace Engineering and more than 17 years of international experience in the space market within GMV. During this time, he has always been involved in projects in the field of orbital mechanics, with particular emphasis on navigation systems (GNSS), precise orbit determination (POD) and space surveillance (SST). As such, he currently heads the division responsible for SST&STM programs in Spain within the Space Surveillance and Traffic Management Business Unit. He has played a leading role in the development of GMV's numerous SST activities, including its leading presence in the Spanish SST program and in various contracts within ESA's Space Safety program and EU Support Framework. Last, but not least, he is an internationally recognized expert in orbit determination and correlation techniques for object cataloguing purposes.
