  • Lecturer in Space Geodesy or Navigation
  • Dept of Civil, Environ &Geomatic Eng
  • Faculty of Engineering Science

Santosh Bhattarai is a lecturer in space geodesy in the Department of Civil, Environmental and Geomatic Engineering (CEGE) at University College London (UCL) with research interests in astrodynamics and space debris dynamics for orbit prediction and orbit determination, and also, in various aspects of global navigation satellite systems (GNSS) and related technologies. He was awarded a PhD in Global Navigation Satellite Systems from UCL in 2015, a BSc in Mathematics and Physics from the University of York in 2009, and is a Fellow of the Higher Education Academy since 2020. 

Research Groups
Research Summary

  • High-fidelity orbit prediction for enhanced space situational awareness (since 2017).
  • Investigations into satellite clock mis-synchronisation errors in global navigation satellite systems (2010-2015).
