What
The controller receives and compares signals across three different GPS radio frequencies: L1, L2, and L5. When jamming floods the L1 band with noise, the system detects the problem by checking for the absence of L2 and L5 signals. For spoofing, it compares the timing and structure of signals across different bands to identify false signals that look legitimate.Related FAQs: How does GPS jamming affect real-time fleet tracking operations?
