Abstract
''SISTEMA DE LOCALIZAçãO DE COMUNICAçõES'' Trata-se de um método e aparelho para localizar um transceptor móvel de comunicação de rádio em um telefone celular ou sistemas de comunicação similares ao celular que utiliza um sistema simplificado para o monitoramento passivo de sinais emitidos pelo transceptor. Duas estações de base de recebimento podem determinar o tempo de chegada do sinal proveniente do transceptor afastado. A referida informação de tempo é então combinada com informação colateral sensível de posição para determinar o local provável do transceptor. A presente invenção tem aplicabilidade particular para o transporte em entradas no sentido de que facilita os serviços de alta emergência e de socorro em estrada em resposta às chamadas de socorro e permite o monitoramento passivo do fluxo de tráfego.'' COMMUNICATIONS LOCATION SYSTEM '' This is a method and apparatus for locating a mobile radio communication transceiver on a cell phone or cellular-like communication systems using a simplified system for passive monitoring of signals emitted by transceiver. Two receiving base stations can determine the arrival time of the signal from the remote transceiver. Said time information is then combined with collateral sensitive position information to determine the probable location of the transceiver. The present invention has particular applicability for transport at entrances in the sense that it facilitates high emergency and roadside rescue services in response to distress calls and allows passive monitoring of traffic flow.
