Sanat K. Biswas, PhD Candidate

Biography

Sanat Biswas is a PhD student in the School of Electrical Engineering and Telecommunications at the University of New South Wales (UNSW). He received BE (2010) in Instrumentation and Electronics from Jadavpur University and M. Tech (2012) in Aerospace Engineering from Indian Institute of Technology Bombay. Sanat is currently associated with Australian Centre for Space Engineering Research (ACSER) and Satellite Navigation and Positioning (SNAP) Laboratory. He has been awarded the Emerging Space Leaders Grant 2014 by the International Astronautical Federation.

 

Research Profile 

Sanat's research focus is non-linear estimation techniques for on-board space vehicle navigation using GNSS receivers. He has developed two new fast Unscented Kalman Filter (UKF) algorithms called the Single Propagation Unscented Kalman Filter (SPUKF) and the Extrapolated Single Propagation Unscented Kalman Filter (ESPUKF). These algorithms can reduce the processing time of the UKF upto 90 percent. The application of the SPUKF and ESPUKF is not limited to space vehicle position estimation and can be applied to any non-linear estimation problems where the UKF can be used.
