APPARATUS AND METHOD FOR RECEIVING SIGNAL IN GLOBAL NAVIGATION SATELLITE SYSTEM
摘要
<p>PURPOSE: Signal acquiring apparatus and method in a global positioning system are provided to obtain satellite signals without an additional hardware by detecting the identifier of a satellite and calculating a code phase and Doppler. CONSTITUTION: A signal acquiring apparatus in a global positioning system includes a first calculating part(420) and a second calculating part(430). The first calculating part detects the identifier of a satellite from a signal from the satellite. A code phase and Doppler are calculated, and a time required for calculation is measured. A second calculating part corrects the code phase and the Doppler using the carrier frequency and the code frequency of the satellite and the calculated values of the first calculating part.</p>
