Modul-Kennung: BV610003

Modulbeschreibung in TUM-Online


Theory courses (3h) and labs (2h). The aim of the course is to

  • get familiar with GNSS, with models involved, and with processing strategies used for precise GNSS positioning applications
  • get experience with GNSS data in practical work

The theoretical part covers:

  • Introduction to GPS and Galileo: position estimation with iterative least-squares method
  • Precise Point Positioning with carrier phase measurements (centimeter accuracy)
  • Estimation of satellite phase and code biases with geodetic networks
  • Estimation of multipath
  • Cascaded Kalman filters, method of Bryson
  • Real Time Kinematic (RTK) positioning
  • Satellite orbit determination: numerical integration, calculation of perturbations, estimation of Keplerian parameters
  • Integer ambiguity resolution with statistical a priori knowledge
  • Inequality constrained ambiguity resolution
  • Statistical evaluation of success rates of carrier phase ambiguity resolution

The practical work includes:

  • development of a simple point positioning tool using matlab
  • experiments using a scientific software package to study the impact of different effects and analysis strategies on positioning results.

The practical work is accompanied by short presentations by the participants of their results.
