What is a "L1 L2 Frequencies"? The Most Authoritative Explanation.

What is GPS L1 L2 L2 and L5 frequency?

For example, L1 frequency is used to track GPS satellite location, L2 frequency is used to track the health of the GPS satellites and the L5 frequency is used to improve accuracy for civilian use such as aircraft precision approach guidance. Let’s look into details about GPS L1, L2, and L5 Frequencies-

What is the frequency of the L1 signal?

The L1 signal uses the frequency 1575.42 MHz ( source). 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.

What frequency is L5?

L5 FREQUENCY INFORMATION Broadcast on the L5 frequency (1176.45 MHz, 10.23 MHz × 115), which is an Aeronautical navigation band. Both the WRC-2000 added space signal component to this aeronautical band so aviation community can manage interference to L5 more effectively than L2.

What frequency is GLONASS L2 (G2)?

GLONASS L2 (G2) is located at 1246 MHz and also uses FDMA. Plans call for future satellites to transmit at a new frequency, called L3, at 1201 MHz, right next to GALILEO E5b). BeiDou B1 is near L1, centered at 1561.098 MHz. A second signal is planned for directly above L1, at 1589.742 MHz.
