A GPS receiver comprising:
- a first GPS antenna coupled to a digital memory, said digital memory storing first digitized signals obtained through said first GPS antenna;
- a second GPS antenna coupled to said digital memory, said digital memory storing second digitized signals obtained through said second GPS antenna;
- a digital processor coupled to said digital memory, said digital processor processing said first digitized signals after being stored in said digital memory to provide a first position information and processing said second digitized signals after being stored in said digital memory to provide a second position information.
A GPS receiver comprising:
- a first GPS antenna coupled to a first digital memory, said first digital memory storing first digitized signals obtained through said first GPS antenna;
- a second GPS antenna coupled to a second digital memory, said second digital memory storing second digitized signals obtained through said second GPS antenna;
- a digital processor coupled to said first digital memory and to said second digital memory, said digital processor processing said first digitized signals after being stored in said first digital memory to provide a first position information and processing said second digitized signals after being stored to provide a second position information.
A method of operating a GPS receiver, said method comprising:
- receiving first GPS signals through a first GPS antenna;
- digitizing said first GPS signals to provide first digitized signals and storing said first digitized signals in a first digital memory;
- receiving second GPS signals through a second GPS antenna;
- digitizing said second GPS signals to provide second digitized signals and storing said second digitized signals in one of said first digital memory and a second digital memory;
- processing in a digital processor said stored first digitized signals to provide a first position information and processing said stored second digitized signals to provide a second position information;
- selecting one of said first position information and said second position information to provide a selected position information.
