Signal GPS Jammers L2 1227.60 MHz

L2 is the second civilian GPS signal, designed specifically to meet commercial needs. Its name refers to the radio frequency used by the signal (1227 MHz, or L2) and the fact that it is for civilian use. There are also two military signals at the L2 frequency. When combined with L1 C/A in a dual-frequency receiver, L2 enables ionospheric correction, a technique that boosts accuracy. Civilians with dual-frequency GPS receivers enjoy the same accuracy as the military (or better). For professional users with existing dual-frequency operations, L2 delivers faster signal acquisition, enhanced reliability, and greater operating range. L2 broadcasts at a higher effective power than the legacy L1 C/A signal, making it easier to receive under trees and even indoors

Half of the GPS constellation now transmits the new civil signal, L2. In a matter of weeks, that number will crest into the majority of the constellation when IIF-10 is set active and operational to users. By the end of the year or early 2016, look for 18 usable satellites transmitting L2. That could be considered a nominal initial operating capability (IOC), though it is unlikely to be declared as such by the Air Force. We can anticipate a full operating capability (FOC) within five years. Many high-precision GPS receivers currently embody L2 signal processing capability.

L2 GPS Jammer has a better signal transmission rate, the general is more professional personnel or agencies to use. So you must use targeted L2 GPS jammer
