Listen Later

Dr. Marek Ziebart, Professor of Space Geodesy at and Director of University College London's Space Geodesy and Navigation Group, is on the Cold Star Project to discuss space object tracking and situational awareness.  


Dr. Ziebart is a fellow of the Fellow Royal Astronomical Society, journal reviewer, and winner of several awards including 2018 Tycho Brahe Award from the Institute of Navigation. Host Jason Kanigan asks about:

  • what space geodesy is
  • a quick look at how GPS works
  • the definition of antenna thrust and its usage
  • what happens  at the Space Geodesy and Navigation Laboratory at UCL
  • what tools Dr. Ziebart uses to collect and process spacecraft orbit determination and prediction
  • outcomes of a European Space Agency project to design a combined navigation and communication system for manned and robotic landings on Mars that he was Principle Investigator of
  • conclusions of a study for the UK's Defence Science and Technology Laboratory, simulating the launches of multiple mega-constellations and their impact on space populations over the next 25 years
  • our shared interests in photography and Dr. Richard Feynman.
