Abstract

"MéTODO PARA DETERMINAR UMA MUDANçA EM UM SINAL DE COMUNICAçãO E USO DESTA INFORMAçãO PARA APRIMORAR RECEPçãO E PROCESSAMENTO DE SINAL SPS". Métodos e aparelhos para determinação de uma posição de um receptor de sistema de posicionamento por satélite (SPS - satellite positionin system) móvel, que está acoplado a um receptor ou transceptor de comunicação. Em um exemplo de método, uma mudança em um sinal de comunicação recebido pelo receptor de comunicação é determinada. Um parâmetro, com base na mudança, é determinado e sinais SPS a partir dos satélites SPS são processados de acordo com o parâmetro. De acordo com detalhes adicionais desse método, a mudança envolve a flutuação do nível do sinal de comunicação e o parâmetro é uma informação de movimento, que especifica uma faixa de freq³ências para busca por sinais SPS no processo de aquisição dos sinais SPS a partir de satélites SPS. Em uma concretização alternativa, a mudança no sinal de comunicação é uma mudança no sinal transmitido em resposta aos comandos de controle de potência. Aparelhos, tal como um sistema de comunicação móvel, que incluam um receptor de SPS e um receptor de comunicação, também são descritos.
