Abstract:
1. A global positioning system receiver for performing both navigation and correlation functions, comprising: (a) a radio frequency down converter; (b) a programmable digital signal processor; (c) a signal processing unit in communication with and residing within said programmable digital signal processor for performing signal correlation, wherein said signal processing unit further comprises; (d) a navigation processing unit in communication with and residing within said programmable digital signal processor for performing navigation functions, wherein said navigation processing unit further comprises; whereby the integration of the navigation and correlation functions in the programmable digital signal processor obviates the need for a separate hardware correlator, the power consumption is reduced as a result of a fewer number of hardware components, and the ability to change the sampling frequency by programming the digital signal processor chip enables the programmable digital signal processor to interface with any type of the radio frequency down converter.
