What
A frequency agile GNSS receiver constantly monitors multiple GNSS frequency bands (L1, L2, L5) and checks for signal strength and integrity. When it detects interference or signal degradation on one band, it rapidly retunes to track signals on a cleaner band using software-defined radio components. It often cross-references multiple satellite constellations like Galileo, which has stronger civilian encryption, to maintain continuous positioning even under jamming or spoofing attacks.
