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

What is the difference between L1 and L2?

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. L2 The L2 frequency was implemented after the L1.

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 are L1 L2 and L5 signals?

If so, here is your quick-and-easy summary explaining L1, L2, and L5 signals and how they are used. The L1 signal is the oldest GPS signal. It has two parts: the Coarse/Acquisition Code (C/A) and the Precision Code (P-code). The P-code is reserved for military use, while the C/A is open to the public.

What is the p code on the L1 band?

GPS L1 Band. The P Code is the precision signal and is coded by the precision code. Moreover the Y-Code is used in place of the P-code whenever the Anti-Spoofing (A/S) mode of operation is activated as described in the ICDs 203, 224 and 225. The PRN P-code for SV number i is a ranging code, Pi (t), 7 days long at a chipping rate of 10.23 Mbps.
