Abstract
posicionamento com base em diferença de tempo de chegada com cálculo de fatores de correção para compensar os desvios de relógio de estações de rede não sincronizadas. a presente invenção refere-se a um método, a uma disposição e a um produto de programa de computador para medição de tempo explora o compartamento relativo de relógios de estações de recepção individuais assim como uma modelagem correspondente para derivar uma diferença de tempo de chegada de um sinal de dispositivo de usuário que pode ser usado para corrigir a diferença de tempo de chegada com base no comportamento de relógio modelado e leva a uma medição de tempo correta de sinais de usuários recebidos sem a necessidade de sincronização.
