We are going to have a seminar on 'Challenges in orbit prediction: from measuring sea level to modelling space debris' on Monday 28th September 2015, 2-3pm, given by Dr Stuart Grey from University College London (UCL).

Abstract and biography are given below.

Date & Time:  Monday 28th September 2015, 2-3pm
Venue:           Room 526, James Watt Building South

Tea/coffee/biscuits before the start.

 

 

Abstract

This talk will cover the non-conservative force models developed at UCL that are able to help generate orbits for satellite altimetry missions that are accurate to the centimetre level.  The basis of these models will be outlined along with how they are used operationally at NASA on the JASON missions and how we are working with ESA to improve the orbits of ESA’s flagship Galileo constellation.   Finally, the challenges in adapting these models to predicting the orbital evolution of space debris will be discussed.

Biography

Stuart Grey is a Lecturer in the Space Geodesy and Navigation Laboratory (SGNL) at University College London (UCL) and works on a number of projects in Positioning, Navigation and Precise Orbit Determination.  Stuart Grey’s primary area of research is in the field of orbital mechanics, specifically the modelling of non-conservative forces on spacecraft and space debris.  He is developing a number of force models to better predict the orbits of scientific space missions and the evolution of the space debris environment. He completed his PhD in Aerospace Engineering (Multi-Agent Systems for Autonomous Spacecraft) at the University of Glasgow.  He joined UCL in 2011 as a Post-Doctoral Researcher in SGNL and accepted a Lecturer position in the same group in 2013.
