A model of a civil Atransport Aircraft Automatic Precise Approach & Landing Control System using DGNSS Information
Hvězda, Michal ; Jalovecký, Rudolf (referee) ; Hlinka, Jiří (referee) ; Vosecký, Slavomír (advisor)
LPV approaches are being published in the Czech Republic nowadays. Their usage is enabled by the EGNOS European satellite augmentation system. However, published decision heights do not allow equivalence with the ILS CAT I precision approach yet. This work presents the model of automated control of aircraft precision approach. Verification of its functionality shows that applicable airspace requirements can be fulfilled for lower values of decision heights than values already published. The model is developed using contemporary methods of model-based development in the tool supporting common processing of both continuous and discrete signals. Although model architecture follows the structure of commonly used ILS system in definition of coordinate system and in establishing control in two separate directions it allows curved approach. Usage of digital navigation data provided by satellite system opens further opportunities in its usage, expansion and improvements. Model functionality in control of flight course, position and height control is verified in the scenarios covering detailed thesis goals. The goals were defined based on definition of precision approach process and include navigation signal drop-out, impact of wind, various flight path angles and curved approach. Analysis of behavior of controlled aircraft dynamics was a stimulator for research of specific system modules up to the application level, i.e. specific simulations of successful precision approaches.

GNSS Precision Approach and Landing CAT II/III
Bach Quoc, Thang ; Vosecký, Slavomír (referee) ; Ptáček, Pavel (advisor)
The content of this work is an overview of precision approach used by GNSS and avionics for operation in low visibility conditions. This thesis describes existing requirements and proposals for new standards that are important to define GBAS performance. The objective of this work is to compare the alternative systems to guide aircraft during precision approach CAT II/III. GBAS operational implementation is additionally devised in this thesis.

Technology of aircraft automatic flight control along an approach trajectory
Kočiš, Martin ; Sklenář, Filip (referee) ; Vosecký, Slavomír (advisor)
This diploma thesis is focused to systems used for automatic control of civil aircraft along an precision approach trajectory. It describes precision approach systems used in the past and their evolutional steps leading to their current and future configuration. The thesis does not put the goal to be a detailed study but to be a publication providing to pilots and students of Aeronautical traffic the introduction to the field of precision approach systems in context to another fields of aeronautical traffic, describing its current status and infer its further development.
