1. A joint pilot detection method comprising:
obtaining a plurality of input signals that are derived from a plurality of satellite signals transmitted from a plurality of global navigation satellite system (GNSS) satellites, respectively, wherein each of the plurality of satellite signals carries a pilot component that is dataless and modulated by a primary code and a secondary code;
obtaining a plurality of code sequences that are replicas of secondary codes of the plurality of satellites, respectively;
performing a plurality of correlation operations according to the plurality of input signals and the plurality of code sequences, for generating a plurality of correlation results, respectively; and
performing pilot detection by jointly considering the plurality of correlation results.
