NA5002 - Integrity control, Augmentation systems

Objectives

General objective:

This course reminds the students the definition and principles of GNSS systems, the description of GPS and its performance and civil aviation requirements. It presents in details the principles of integrity control and the augmentation systems GBAS, SBAS and ABAS(RAIM only as INS hybridisation is tackled in a different course).

Detailed objectives:

At the end of the cours, the student shall :
- be able to compute a GPS position based on pseudo-distance measurements,
- know the typicla error budget for pseudo distance measurements and the associated failures,
- understand ICAO requirements for a GNSS positioning system
- understand the processes implemented in integrity monitoring systems to satisfy these requirements,
- understand the computations implemented in RAIM integrity monitoring algorithms
- know the working principle and architecture of an SBAS system
- know the working principle and architecture of an GBAS system.
