Yes, the jammer modules can block GPS positioning. The GPS jammer blocks the reception of GPS satellite signals by emitting interference or false signals, thereby preventing positioning devices from obtaining location information. Its working principle is mainly divided into two technical systems: the suppression system uses high-intensity signal coverage to disable the receiver, and the deception system uses forged signals to mislead the receiver. The effective shielding distance is usually within the range of several meters to tens of meters, depending on the power of the equipment.
