Method for determining a position of a low-power radio-frequency signal receiver |
摘要 |
<p>The method involves configuring one of correlation channels (7') of a correlation stage (7) of a radio frequency signal receiver (1) to search a satellite based augmentation system type visible geostationary satellite. Instructions are provided to calibrate a frequency of timing signals delivered by digitally controlled oscillators integrated to the channel or calibrate clock signals (CLK, CLK16) produced by a clock signal generator (5). The other channels are configured to search global positioning system type satellites to calculate position and time in a microprocessor unit (12). An independent claim is also included for a radio-frequency signal receiver comprising a receiving unit for receiving radio-frequency signal.</p> |
