METHOD FOR THE ACQUISITION OF SIGNALS OF A GLOBAL NAVIGATION SATELLITE SYSTEM

摘要

A method of acquisition of a received signal received from a Global Navigation Satellite System, comprising: obtaining a snapshot of the received signal; correlating the snapshot with a locally- generated signal, wherein said correlating includes: trying a phase delay value indicative of an hypothesized phase delay of the locally-generated signal with respect to the snapshot; and obtaining a partition of the snapshot and the locally-generated signal into corresponding pluralities of blocks, and calculating partial correlation integrals for each block of said plurality of blocks. Said corresponding pluralities of blocks include each a first block having a time duration related to the phase delay value.
