GPS receiver having fast resolution of carrier phase ambiguity

A signal receiver having a fast resolution of carrier phase ambiguity during acquisition of an incoming signal having a carrier and incoming data, including:

• a digital signal processor for receiving a representation of said incoming signal and providing signal correlation information and carrier phase observable information for said incoming signal;
• an executable signal tracking code for receiving said signal correlation information and providing a data stream representative of said incoming data;
• a carrier ambiguity detector for storing expected data having time-tags for said incoming signal, receiving said data stream, comparing said data stream to said expected data according to said time tags, and providing a phase resolution indicator for indicating a first carrier phase when said stream data is inverted from said expected data and a second carrier phase when said data stream is non-inverted from expected data;
• and
• an executable navigation code coupled to the signal tracking code and carrier ambiguity detector code for using said phase resolution indicator for eliminating an ambiguity in said carrier phase observable information.

A method for fast resolution of carrier phase ambiguity during acquisition of an incoming signal having a carrier and incoming data, comprising steps of:

• storing time-tagged expected data for said incoming signal;
• receiving a data stream representative of said incoming data;
• receiving a clock time synchronized to said incoming data;
• using said clock time for issuing certain said expected data corresponding to said clock time;
• comparing said data stream to said certain expected data;
• and
• issuing a phase resolution indicator for indicating a first carrier phase when said data stream matches an inverted said certain expected data and a second carrier phase when said data stream matches a non-inverted said certain expected data.
