Question

What does 'unjammable' really mean for BeiDou-3 B3A military signal in fleet tracking?

Answer

The 'unjammable' label refers to signal integrity against deliberate interference, not perfect availability. B3A uses military-grade encryption and wider bandwidth, making it exponentially harder for cheap jammers to spoof or overpower the signal. However, it doesn't help with physical signal blockage in urban canyons, tunnels, or underground garages.
