Objetivos de este TFC: 1.- Aprender a utilizar la herramienta gLAB para realizar el posicionamiento preciso de receptores GPS. 2.- Analizar los efectos en la precision del sistema GPS de las diferentes fuentes de error. 3.- Llevar a cabo procesamientos del tipo "Standard Positioning Service" (SPS) y "Precise Point Positioning" (PPP). 4.- Utilizar diferentes estrategias para el posicionamiento cinematico de dos vehiculos con receptores GPS embarcados: Una aeronave ligera y un satelite en orbita baja. 5.- Discutir las ventajas y desventajas relativas de utilizar diferentes estrategias de posicionamiento cinematico GPS.

The main aim of this project is to use the gLAB program to analize the data generated by some GNSS receivers. The program gLAB was created by the GAGE/UPC research group, with the purpose of offering an easy to use tool to the students who want to get more deep knowledge on GPS, as well as to professionals who need precise positioning. In this project we will explain the program’s main characteristics in a theoretical way and through examples where it is explained how to get a precise positioning of GPS receivers. In this document we can also find the analysis of the different sources of error that make the GPS system not so precise to be used in aeronautical fields, such as to know the correct positioning of an airplane or to take off and landing guidance. Along the project I have carrier out a series of experiments with the SPS and PPP processing strategies to localize a ground station with a static strategy, and the route of a light aircraft with a GPS receiver has been followed. For the latter case a kinematic positioning strategy was used. To end up we explain how to plot these routes using Google-Earth
