FAQ Answer

Question

How does BeiDou satellite navigation work when GPS signals are jammed?

Answer

BeiDou transmits on different center frequencies and uses distinct signal codes compared to GPS. When GPS frequencies like L1 and L5 are jammed with noise, a receiver that can process BeiDou signals can ignore the jammed GPS band and calculate position purely from BeiDou satellites. This allows vehicles to maintain location tracking even when GPS is disrupted.
