The receiver of the global positioning system and process of reception of a signal system of global posicionamneto

摘要

"Global positioning system receiver and reception process of a signal of global positioning system.A receiver of the global positioning system includes a terminal input signal to receive a signal from the global positioning system having a PRN code entry entry of a sourceSignals from the global positioning system. A code generator is configured to generate a local PRN signal PRN site.A discriminator is coupled with the terminal of the input signal and the local PRN code generator and configured to compare the input signal and the local PRN code and generate a signal discriminator (cContaining a positive and a negative part.A processor (1205) is coupled to the discriminator and configured to receive the signal discriminator to process the signal discriminator for determining a code bit and determine a distanceA source of signal of global positioning system based on the code of the bit.In one implementation,The discriminator includes an acquisition mode configured to acquire the PRN code entry in which the discriminator has a first width of the door and a track mode configured to RASTRear code PRN in which the discriminator has a second width smaller than the first width of door to door. Among the advantages of the invention include rejection of signal multivia perfected.
