Abstract:

The law of global navigation satellite systems is a nascent, yet growing academic field. The subject matter it studies, GNSS, has been and is becoming ever-more important in the modern world, both for transportation, as well as for commerce. Indeed, globalization has seen billions of euros in trade associated with both nautical and aviation shipping, and this trend is likely to grow larger with the passage of time. Additionally, the nations of the world are fast realizing the potential of GNSS to make their aviation industries more robust and efficient, with integration of GNSS into air traffi

Abstract:

In global navigation satellite systems (GNSS) a fundamental operational component is the calculation of the orbits of the system spacecraft. This requires understanding and modelling the forces that act on the spacecraft. Solar radiation pressure (SRP) is the force caused by the impact of solar photons on the spacecraft surface. For GNSS spacecraft this is a significant force. If SRP is not included in the force model, then the calculated position of the spacecraft can be in error by between one and two hundred metres after one 12-hour orbit. SRP can be modelled using either analytical or empi

Abstract:

Global Navigation Satellite System Reflectometry (GNSS-R) is based on the concept of receiving GPS signals reflected by the ground using a passive receiver. The receiver can be on the ground or installed on a small aircraft or UAV and collects the electromagnetic field backscattered from the surface of the Earth. The received signals are then analyzed to determine the characteristics of the surface. GNSS-R has gained increasing interest over the last two decades as an efficient tool for remote sensing, thanks to the development of positioning systems. GNSSR finds application in several fields

Abstract:

The use of Global Navigation Satellite System (GNSS) for air navigation brings important advantages to aviation since it is able to reduce routes, save fuel and diminish greenhouse gas emissions. It is also a more flexible and precise navigational aid that improves flight operations at critical moments such approach, landing and take-off. However, the GNSS signal may fail; and depending on the moment of this failure, its failure could cause an accident. Therefore, air navigation service providers' liability in using GNSS is a concern.

The existing air navigation services have many shortcomings and a reform was necessary.

However, GNSS have weaknesses which can be reduced but will never be fully eliminated.

Abstract:

The aim of this thesis is to graphically interpret navigation messages from a prototype of global navigation satellite system. The resulting application is implemented in Python programming language for Windows operating system and follows requests from researchers developing the prototype. Necessary terminology together with graphical user interface programming possibilities of object-oriented language Python is a base for theoretical background of this text. Practical part of this research describes a solution for receiving generated messages from the prototype as well as their storing and f

Abstract:

El gran éxito y la facilidad de uso de los sistemas de navegación global por satélite (GNSSs) ha conducido a la definición de una gran cantidad de aplicaciones basadas en GNSS sin precedentes. De hecho, la tendencia muestra una nueva era de aplicaciones basadas en GNSS, las denominadas aplicaciones críticas, en las que la integridad física de los usuarios puede estar en riesgo en caso de un fallo del sistema. Un requisito importante en estas aplicaciones es la integridad, definida como una medida de la fiabilidad y confianza que se tiene en la información proporcionada por el sistema. Los prim
