Claim:
1. A global navigation satellite system (GNSS) receiver, the receiver comprising: an antenna configured to receive a GNSS signal; a first plurality of GNSS channels coupled to receive the GNSS signal, wherein each of the first plurality of GNSS channels is configured to integrate the GNSS signal over an accumulation window having a predetermined length of time to output a navigation message bit, and wherein the accumulation windows of the first plurality of GNSS channels are delayed relative to each other; a second plurality of GNSS channels coupled to receive the GNSS signal, wherein each of the second plurality of GNSS channels is configured to integrate the GNSS signal over an accumulation window having the predetermined length of time to output a navigation message bit, and wherein the accumulation windows of the second plurality of GNSS channels are delayed relative to each other; and a processor coupled to receive the navigation message bits from the first plurality of GNSS channels, wherein the processor is configured to identify one of the first plurality of GNSS channels that is synchronized with the GNSS signal based on the navigation message bits.
