What is a "L5 Frequency"? The Most Authoritative Explanation.

What are L5 GPS signals?

The insertion of L5 GPS signals is part of the US Department of Defense’s modernization activities. Now there are three civilian GPS frequencies: L1 at 1575.42 MHz, L2 at 1227.60 MHz, and L5 at 1176.45 MHz. Each frequency has unique properties that make it better suited for certain types of applications.

What is L5 radio?

L5 is broadcast in a radio band reserved exclusively for aviation safety services. It features higher power, greater bandwidth, and an advanced signal design. Future aircraft will use L5 in combination with L1 C/A to improve accuracy (via ionospheric correction) and robustness (via signal redundancy).

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 is the difference between L2 and L5?

However, since L2 is newer, its infrastructure is not yet complete. Because of this, it cannot be used on its own: it must be used along with L1 frequencies ( source). L5 is the third GPS signal, operating at 1176 MHz. It is the most advanced GNSS signal yet, but it is still in its infancy, with deployment scheduled for 2021 ( source).
