Course Objective

Positioning is the determination of where we are on earth. Navigation, on the other hand, is the determination of where we should go. These two where questions have long occupied
the mind of mankind from ancient times. In early times basic astronomic devices and methods were used to determine the position. Stars and the sun were the greatest helpers to navigate in
the open sea. Artificial satellites have been considered as important tools for positioning and navigation in the following years after the Sputnik s launch in 1957. The world s first spacebased
positioning system is the Global Positioning System (GPS) and its first satellite was launched into its orbit in 1978. In the second half of the 80s military and science community
began to use GPS for positioning, surveying, determination of earth surface deformations, etc. The GPS was declared operational in 1995 and since then continuous positioning has been
possible 24 hours a day. Another positioning and navigation systems are the Russia s GLONASS, EU s Galileo, China s Beidou and Japan s QZSS. All positioning and navigation
systems have one common name: Global Navigation Satellite Systems (GNSS). The operating concepts and methods are similar for all systems despite their different names. This course
aims to teach students tools and methods for achieving positioning and navigation with the help of GNSS.

Learning Outcomes of the Course Unit

1   To identify components of a Global Navigation Satellite Systems
2   To recognize different receiver types and differentiate between different observation types.
3   To collect observations in the field in different environments
4   Students will be able to categorize among observation errors which can be eliminated, reduced, modeled.
5   Students will identify absolute and relative positioning concepts.
