What is a "L2 Frequency"? The Most Authoritative Explanation.
What is the L1 and L2 frequency of GPS?
In the case of the original GPS design, two frequencies are utilized; one at 1575.42 MHz (10.23 MHz × 154) called L1; and a second at 1227.60 MHz (10.23 MHz × 120), called L2. The C/A code is transmitted on the L1 frequency as a 1.023 MHz signal using a Bi-Phase Shift Key ( BPSK) modulation technique.What is the difference between L2 and L5 frequencies?
The frequency was specifically chosen because the aviation industry can manage interference much more effectively on L5 than L2, and the frequency band is internationally protected by the International Telecommunication Union (ITU) for aeronautical radionavigation services.What is the difference between L1 and L2C?
L2C is a new civilian-use signal broadcast on the L2 band at a frequency of 1227.60 MHz, which enables greater speed than L1. There are two military signals on the L2 frequency but the technology using the band has been specifically designed for commercial needs.Can civilians use the L2 frequency for military purposes?
There are two military signals on the L2 frequency but the technology using the band has been specifically designed for commercial needs. With the use of dual-frequency receivers, civilians can now enjoy the same level of accuracy as military applications.
