G3:  -  1.00-3.00pm          Inertial Navigation Systems (Instructor Joe Elchynski)  -   Lake Geneva Room 1st Floor, Rydges Lakeside

Inertial Navigation is a very important alternative or supplement to GPS. However, its performance and operation principles are much less understood. This course gives a solid foundation in Inertial measurement so that the users can adopt the most appropriate system for their needs. The following topics will be covered in the presentation:

§         Explanation of the performance parameters of modern Inertial Measurement Units

§         Principles of operation of modern INU's (RLG, FOG, DQI and others ) incl performance

§         IMU/GPS Integration

§         Overview over vendors and their products

G4:  -  3.15-5.15pm            Pseudolites (Instructor Professor Chris Rizos)  -   Lake Geneva Room 1st Floor, Rydges Lakeside

Pseudolites are ground-based transmitters of GPS-like signals ("pseudo-satellites") that can significantly enhance the receiver-satellite geometry in circumstances where complete sky coverage is not available.  In such cases pseudo-range and carrier phase measurements on the pseudolite signals can augment the GPS observations, leading to improved accuracy and reliability of positioning results.  In principle pseudolites can even replace the GPS satellite constellation completely, making feasible indoor positioning using standard (or slightly modified) GPS receivers.  This course will:

§         introduce the pseudolite technology,

§         discuss the modelling issues associated with GPS+pseudolite systems and pseudolite-only systems,

§         describe the implementation issues,

§         discuss some of the scenarios in which such systems may be deployed, and

§         mention some of the current and future applications of pseudolite systems.

Objective

This series describes the various alternative hardware systems available for navigation, such as GPS, the European Alternative GALILEO, Inertial Navigation and Pseudolites.
