Professor Raja Sengupta, along with team members Venkatesan Ekambaram and Kannan Ramchandran, were among the six winners of the US Department of Transportation's Research and Innovative Technology Administration (RITA) competition seeking ideas for using wireless technology to enable vehicles to communicate with one another.
Their winning submission, "Robust GPS: Enhancing Accuracy and Security Using DSRC," uses DSRC signals on board vehicles to improve weakened positioning information and to correct illegally "jammed" GPS signals. This enables DSRC-equipped vehicles to automatically correct the GPS positioning of other similarly equipped vehicles.
