GNSS für präzise Anwendungen

ECTS: 6

Modul-Kennung: BV610003

Inhalte:

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.
