Abstract

Las tecnicas para calcular la velocidad de una terminal en un sistema de comunicacion inalambrico. El movimiento de los resultados de la terminal en un cambio Doppler en la frecuencia de cada senal transmitida recibida en la terminal. En un metodo, son determinadas las posiciones de la terminal, una estacion base, y cada uno de dos o mas satelites inicialmente. Tambien se puede determinar un indice de cambio residual de pseudo-rango por cada satelite, por ejemplo, basado en (1) un error de frecuencia de banda de base calculado que incluye un cambio de frecuencia Doppler debido al movimiento de la terminal y (2) un cambio de frecuencia Doppler calculado debido al movimiento del satelite. Entonces se forma un conjunto de ecuaciones basado en las posiciones determinadas de la terminal, la estacion base y los satelites y los indices de cambio residual de pseudo-rango determinados para los satelites. La velocidad de la terminal puede ser calculada posteriormente basada en un conjunto de ecuaciones.
