Positioning Algorithms Group

Research topics

Personal positioning refers to computing the 3D position coordinates of a portable handset using a variety of measurements. Combining information from satellite-based systems (such as GPS), terrestrial radio systems (such as cellular networks), and on-board sensors has presented numerous new challenges, especially as some of the measurements were not originally intended to be used for positioning purposes.

Meanwhile, the increasing computational capabilities of the mobile handset are making it possible to take advantage of more sophisticated mathematical methods to compensate for the scarce and incomplete data.

The group studies the point-position and nonlinear filtering techniques required in modern personal positioning, including

  • Bayesian inference,
  • sequential Monte Carlo methods,
  • (extended) Kalman filters, and
  • numerical integration methods

In addition, we research statististical and geometric models pertaining to the problem as well as efficient numerical algorithms for positioning/tracking computations.
