Metodología para la generación de un modelo troposférico a partir de medidas meteorológicas y datos GPS

Abstract

The use of GPS (Global Positioning System) coordinates for positioning in the earth's surface consists of determining the distance between the satellite and receiver which are made by using radio frequency signals. Due to the influence of atmospheric water vapor in the troposphere and the layer elevation angle of satellite signals suffer a delay, called tropospheric delay (Dtrop). This delay can be estimated using GPS observations and surface meteorological measurements. Were achieved tropospheric delay estimates average BOGA continuous monitoring station. The aim of this paper is to present the application of GPS and the study of the variables and the methodology to be taken into account for the generation of a local tropospheric model through superficial meteorological measurements with data from the IGAC and IDEAM.
