Abstract

"RECEPTOR DE SISTEMA DE POSICIONAMENTO POR SATéLITE COM REFERêNCIA AO CIRCUITO OSCILADOR E MéTODOS PARA O MESMO". Um método em um receptor móvel sem fio tendo um oscilador, incluindo determinar uma mudança no erro de freq³ência baseada na rede celular do oscilador (250), com base em uma diferença (230) entre o erro de freq³ência baseado na rede celular do oscilador e um erro de freq³ência baseado na rede celular de referência (210) do oscilador, determinar um primeiro erro de freq³ência do oscilador ao somar (250) um erro de freq³ência do oscilador baseado no receptor do sistema de posicionamento por satélite de referência (220 ) com a mudança no erro de freq³ência baseada na rede celular do oscilador.
