Abstract
sistema de comunicação de rádio. a invenção refere-se a um sistema para formar uma rede de comunicação assíncrona para receber transmissores de cliente, incluindo estações base que são remotas uma da outra, dita rede habilitando a geolocalização dos transmissores de cliente. para este propósito, o sistema inclui uma pluralidade de transmissores de referência estacionários, as posições de quais são conhecidas e cada um dos quais transmite um sinal de baliza específico em uma banda de frequência incluída dentro da banda de frequência da rede. a geolocalização de um transmissor de cliente é executada através de multilateração levando pares de estações base em conta, cada par consistindo em estações base capazes de receber os sinais do transmissor de cliente e os sinais de um único transmissor de referência, e calculando a diferença entre os tempos que o sinal do transmissor de cliente chegou nas estações base, dita diferença sendo determinada calculando, para cada estação base, a diferença entre os tempos de chegada do sinal transmitido pelo transmissor de cliente e daquele transmitido pelo transmissor de referência.
