This course teaches how signals from orbiting satellites that are 20,000 km above the earth can be used to locate terrestrial objects to an accuracy of several meters down to a fraction of a centimeter. It begins with a brief review of satellite navigation history, then describes the major system components and the coordinate frames in which location of satellites and targets is described. The main portion of the course focuses on the features and techniques in target receivers that determine location and time estimates, including differential GNSS (Global Navigation Satellite System), and presents sources of error and the necessary relativistic corrections. The existing and developing global and regional satellite navigation systems are described, as well as major improvements to the veteran implementations, the American GPS and Russian GLONASS. Integration of inertial measurement systems (IMS) with satellite positioning is also explained. The course concludes with a discussion of GNSS implementation.
Overall, this course will help you understand how satellite navigation works, what its features and limitations are, which satellite navigation systems are available or being developed and how to more effectively utilize them.
Who Should Attend
Potential course attendees will be people with an engineering background employed in companies developing or using wireless positioning and location and who need a more than basic understanding of satellite navigation. Course participants will include personnel at engineering and managerial levels, as well as marketing executives and students. In general, the course is for those who are curious to understand how GNSS (Global Navigation Satellite System) works.
