#### Osaamistavoitteet

After completing the course, the student knows how to - describe the structure of satellite positioning system and explain the tasks of the segments - describe the structure of positioning signal and explain the properties of the signal components - describe the structure of a satellite navigation receiver and explain the tasks of the main functional blocks - classify the error sources of positioning measurements and estimate their effect on positioning accuracy - form a geometry matrix and use it to obtain position estimate - define the coordinate frames important in satellite positioning, transform coordinates between the systems
