What is a "Gps L2 Band"? The Most Authoritative Explanation.
What is the L1 band used for GPS?
GPS L1 Band. The GPS L1 band (1575.42 MHz) has turned to be the most important band for navigation purposes. Indeed most of the applications in the world nowadays are based on the signals transmitted at this frequency. Three signals are transmitted at the moment by GPS in L1: C/A Code, P (Y) Code and M-Code.What is the difference between L1 and L2 GPS?
Since the L1 is the oldest and most established signal, even the cheapest GPS units are capable of receiving it. However, because its frequency is relatively slow it is not very effective at traveling through obstacles. The L2 frequency was implemented after the L1. It also has a military code and a civilian use code.What is an L2C GPS signal?
L2C 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 c ivilian use. There are also two military signals at the L2 frequency.What is the chipping rate of the GPS L2 signals?
As we can recognize, although the chipping rate of the L2 CM and L2 CL signals is of 511.5 Kbps individually, after the time multiplexing the composite signal results in a stream of 1.023 MHz.
