Summary

All fundamental principles behind modern satellite positioning to acquire, track and evaluate direct and indirect satellite signals and process them in relation to example applications: Earth monitoring (landslides,...), high precision positioning (automated driving, robots,...) and time transfer.

Content

Concept of satellite positioning
- basic principals & reference frames
- orbit computation & simple positioning

 

Signal modulation and structure
- RF propagation in space
- signal structure including new Galileo modulations

 

Receiver technology
- signal preprocessing
- signal acquisition & tracking

 

Error models and differencing concepts for special and high precision applications
- code and carrier phase measurements
- linear combination of observations

 

Algorithms for reliable positioning
- code and carrier-phase smoothed-code
- carrier-phase cycle ambiguity determination

 

Algorithms for environmental sensing
- water vapor estimation
- total electron content estimation
- GNSS reflectometry

Keywords

GNSS, GPS, GLONASS, Galileo, satellite, positioning, signal modulation, detection, estimation, signal processing, ionosphere, troposphere, automated vehicles, space, time-transfer, Earth sensing, drones.
