Abstract

"IDENTIFICAçãO DE REPETIDORA EM SISTEMA DE DETERMINAçãO DE POSIçãO". Um método de identificação de se um primeiro sinal recebido em uma estação assinante foi retransmitido por uma repetidora. O método envolve a medição na estação assinante de uma diferença de tempo de chegada entre o primeiro sinal e um segundo sinal. Um hiperbolóide ou outra superfície de solução potencial é então formado a partir da diferença de tempo de chegada medida. Uma determinação então é feita de se ou não o primeiro sinal foi retransmitido por uma repetidora com base nas informações derivadas da superfície de solução potencial.
