Global Positioning System, generally known as GPS, is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Each GPS satellite transmits two carrier signals in the microwave range, designated as L1 and L2. These frequencies located in the L-Band are between 1000 and 2000 MHz. Civil GPS receivers use the L1 frequency with 1575.42 MHz. The L1 frequency carries the navigation data as well as the SPS code-standard positioning code. Due to the characteristics of GPS, the GPS L1 1500-1600 MHz jammer appears.
