Abstract
"SISTEMA COM MARCAçãO D<39>áGUA DE FREQüêNCIA DE REPETIDORA DE LINK DIRETO". São descritos um sistema e um método para marcação d<39>água de freqüência de repetidora de link direto (FLRFWM) que permitem localização de posição acurada de estações móveis em áreas em que estão presentes repetidoras por marca d'água de sinais repetidos com informações de repetidora. Uma repetidora marca um sinal de link direto com uma marca d'água (exclusiva ou não exclusiva) de modulação de freqüência rápida a cada vez que um sinal passa pela repetidora. Uma estação móvel detecta e/ou identifica a marca d<39>água de freqüência rápida no sinal de link direto para determinar informações de repetidora que auxiliam a entidade de determinação de posição da rede ou o sistema de localização de posição de estação móvel a determinar a localização da posição pelo uso de AFLT e/ou sistemas A-GPS. Um sistema de marca d<39>água de freqüência rápida de link direto aqui descrito propicia impacto mínimo sobre o desempenho do FL, AFLT e GPS, boas detecção, identificação probabilidade de alarme falso, curto tempo para detecção / identificação e boa sensibilidade de detecção / identificação.
