# Is there an anti-jammer device?

### Question

Is there an anti-jammer device?

### Answer

Unfortunately, there is no GPS device that can be protected from jammers. Nevertheless, if the device has assisted GPS (LBS detection), it could provide a radius in which it is possible to locate it, directly aiding in the device search.
