GPS signals are transmitted across different frequencies, each designed to support reliable satellite positioning. The primary civilian GPS signals include L1, L2, and L5, which operate at different frequencies and help receivers improve accuracy and signal reliability.
Multi-frequency GNSS receivers can compare signals across bands to reduce ionospheric errors and support high-precision applications such as surveying and navigation. For a quick overview of the major signal ranges, this guide to
gps frequency bands provides useful technical information.
