Method for the acquisition of signals of a global navigation satellite system

A method of acquisition of a received signal received from a global navigation satellite system, comprising:

• obtaining a snapshot of the received signal;
• and
• correlating the snapshot with a locally-generated signal, wherein said correlating comprises:
• trying at least one phase delay value indicative of a hypothesized phase delay of the locally-generated signal with respect to the snapshot;
• 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 each comprising a first block having a time duration related to a phase delay value.

A global navigation satellite system receiver comprising functional modules capable of being configured for:

• obtaining a snapshot of a received signal;
• and
• correlating the snapshot with a locally-generated signal,
• wherein said correlating comprises:
• trying at least one phase delay value indicative of an hypothesized phase delay of the locally-generated signal with respect to the snapshot;
• obtaining a partition of the snapshot and the locally-generated signal into corresponding pluralities of blocks each comprising a first block having a time duration related to a phase delay value;
• and
• calculating partial correlation integrals for each block of said plurality of blocks.
