The NAVSTAR Global Positioning System (GPS) is a satellite-based navigation and positioning system which includes a constellation of 32 satellites, remote control stations and its receivers and can be used for determination the geographical positions of its users. GPS signal simulator needs for test and verification of GPS receiver's performances in special applications at the Laboratory. For this mission we should simulate the various static and dynamic scenarios for GPS receiver tracks and generate GPS signals for all the satellites. For GPS signals, generation of all its elements like the Navigation messages, C/A codes, frame and subframe structures should be defined and used in this project.
