Summary:Procedure to estimate the position of a receiver by means of gnss satellites. Multifrequency and multiconstelation procedure for the determination of the position of a receiver by means of gnss satellites, which thanks to the steps of: obtaining the pseudorange, ionospheric bias and ambiguity vector, determination of a covariance matrix for each of the previous parameters and estimation of the position of the receiver and the lag of its clock from the pseudo-distances, its covariance matrix, and precise ephemerides of the satellites. The procedure thus allows to process triple frequency data and combine signals from different navigation systems.

Procedimiento multifrecuencia y multiconstelación para la determinación de la posición de un receptor mediante satélites GNSS, que gracias a las etapas de: obtención de la pseudodistancia, sesgo ionosférico y vector de ambigüedad, determinación de una matriz de covarianza para cada uno de los parámetros anteriores y estimación de la posición del receptor y el desfase de su reloj a partir de las pseudodistancias, su matriz de covarianza, y efemérides precisas de los satélites. El procedimiento permite así procesar datos triple frecuencia y combinar señales de diferentes sistemas de navegación.
