L1, L2, L5 Frequencies

L1, L2, and L5 are frequency bands used by Global Navigation Satellite Systems (GNSS), including GPS. - **L1** (1575.42 MHz) is the primary frequency used for civilian GPS signals, allowing basic location services. - **L2** (1227.60 MHz) is mainly for military use but supports civilian applications for improved accuracy and reliability. - **L5** (1176.45 MHz) is a newer frequency that offers high precision and safety-critical services, enhancing navigation performance, especially in urban areas. Together, these frequencies enable better positioning and navigation capabilities for various users, from everyday drivers to aviation and maritime industries.
