1、 Rec. UIT-R SA.1415 1 RECOMENDACIN UIT-R SA.1415 COMPARTICIN ENTRE LOS SISTEMAS DEL SERVICIO ENTRE SATLITES EN LA BANDA DE FRECUENCIAS 25,25-27,5 GHZ (Cuestin UIT-R 225/7) (1999) Rec. UIT-R SA.1415 La Asamblea de Radiocomunicaciones de la UIT, considerando a) que la banda de frecuencias 25,25-27,5 G

2、Hz est atribuida al servicio entre satlites, limitado por el nmero S5.536 del Reglamento de Radiocomunicaciones a las aplicaciones de investigacin espacial y de exploracin de la Tierra por satlite, y tambin a transmisiones de datos procedentes de actividades industriales y mdicas en el espacio; b) q

3、ue se ha identificado la necesidad de la banda 25,25-27,5 GHz para los sistemas de enlaces de satlites de retransmisin de datos y enlaces de proximidad, recomienda 1 que los sistemas de enlaces de proximidad utilicen las partes de la banda atribuida comprendidas entre 25,25 y 25,60 GHz y 27,225 y 27

4、,5 GHz y los sistemas de enlaces de satlites de retransmisin de datos utilicen el resto de la banda atribuida cuando ambos sistemas estn implantados en una plataforma espacial comn; 2 que se utilicen los mecanismos estndar de comparticin, como la comparticin de tiempo, la diversidad espacial, la polarizacin de la antena y la diversidad de frecuencia, para compartir la banda atribuida en las dems circunstancias.
