Fundamentos y aplicaciones del Posicionamiento Puntual Preciso (PPP: Precise Point Positioning)

Abstract

[ES]El posicionamiento puntual preciso (PPP) permite la determinaci?n de la posici?n de un punto con un ?nico receptor GNSS (Global Navigation Satellite System), mejorando la precisi?n de la medida sin necesidad de recurrir a t?cnicas de posicionamiento diferenciales. Para ello, utiliza los observable de c?digo y fase, en doble frecuencia, datos de ?rbitas precisas y datos de reloj de sat?lite, como los que proporcional el IGS (International GNSS Service). Este trabajo tiene como pr?sico comprender PPP, analizar sus ventajas e inconvenientes y describir sus aplicaciones. Para ello es necesario contrastar los modelos matem?ticos utilizados en esta t?cnica, examinar sus aplicaciones y evaluar las precisiones alcanzadas en las mismas. De la misma manera se realiza una comparaci?n de la precisi?n obtenida mediante PPP y diferentes t?cnicas diferenciales. Una vez se definieron los conceptos y modelos matem?ticos de PPP, se realiz? la exploraci?n y descripci?n de las herramientas inform?ticas utilizadas en el prcesamiento de datos GNSS bajo la t?cnica PPP. Lo que dio como resultado la implementaci?n de doce herramientas inform?ticas clasificadas entre software comercial, cient?fico, acad?mico y servicios en l?nea. Por ?ltimo, se encuentran los resultados, an?lisis y comparaci?n de coordenadas finales procesadas. Se puede concluir que PPP ofrece una alternativa interesante frente a la forma tradicional de posicionamiento diferencial, ya que permite procesar datos de modo est?tico, cinem?tico y en tiempo real, esta t?cnica se ha consolidado como una metodolog?a para densificar redes geod?sicas de primer orden.
