Abstract

LA INVENCION SE REFIERE A LOS RECEPTORES DE POSICIONAMIENTO POR SATELITE. PARA REDUCIR EL EFECTO NEFASTO DE LOS TRAYECTOS REFLEJADOS EN LA MEDIDA DE POSICION GPS QUE NO DEBERIA TENER EN CUENTA MAS QUE EL TRAYECTO DE LAS SEÑALES DE RADIOFRECUENCIA EN LINEA RECTA, SE PROPONE SEGUN LA INVENCION UN PROCEDIMIENTO QUE PERMITE POR SIMPLE CALCULO DE EXTRAPOLACION ELIMINAR LA INFLUENCIA DE LOS MULTITRAYECTOS. SE EFECTUAN MEDICIONES POR CORRELACION CON CUATRO CODIGOS SEUDOALEATORIOS E1, E2, L1, L2 REPLICAS DE UN CODIGO RECIBIDO DE UN SATELITE. SE EFECTUA UN PRIMER CONJUNTO DE MEDICIONES DE ENERGIAS DE CORRELACION Y DE TIEMPO RECIBIDO CON CODIGOS E1, L1 QUE CORRESPONDEN A UN AVANCE Y A UN RETARDO D RESPECTO A UN CODIGO PUNTUAL, Y UN SEGUNDO CONJUNTO DE MEDICIONES CON LOS CODIGOS E2, L2 QUE CORRESPONDEN A UN AVANCE Y A UN RETARDO K.D (K DIFERENTE DE 1 Y DE 0). POR EXTRAPOLACION LINEAL, SE DEDUCEN LAS MEDIDAS PARA K=0, QUE CORRESPONDE EN EL CASO DE QUE LOS MULTITRAYECTOS NO TENGAN EFECTO. LA INVENCION PUEDE APLICARSE CON UN SOLO BUCLE DE REALIMENTACION DE CODIGO ALEATORIO O DOS BUCLES INDEPENDIENTES.
