ECTS: 6
Modul-Kennung: BV610003
Modulbeschreibung in TUM-Online
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.
