| Univ. Bremen Prof. Dr. C. Lämmerzahl, Dr. Dennis Philipp | The Global Navigation Satellite System (S2, elective, 3 ECTS) |
| Learning Outcomes: | Understanding of the working principles of global navigation satellite systems. In particular (i) the physical and theoretical principles of positioning, (ii) GNSS satellites, payload, clocks; (iii) the technology requirements. |

| Prerequisites | None |
| Program | (i) The physical requirements regarding the main working principles. Here clocks, the electromagnetic signals propagation in the Earth’s atmosphere, and the targeted accuracy are discussed. (ii) The theoretical analysis of the whole problem has to be carried through. This includes basic effects of the moving clocks (special relativistic time dilation) and clocks in gravitational fields (gravitational redshift) and the calculation of the position from the clock signals. Theoretical concepts within geodesy regarding reference surfaces and coordinate systems such as WGS84 will be introduced. (iii) The technological realization is described. |
