FAQs About GPS Jammers – How They Work & Legality
Q: How does a GPS jammer work?
A: The working principle of GPS jammer is similar to using a louder speaker to cover other people's voices.GPS satellites transmit high-intensity noise and real noise that affects the satellite, making your device (mobile phone/navigation) "unable to hear" satellite signals.①Start automatic scanning of GPS channel map (similar to radio search)②Continuously transmit interference signals to cover the area (like using white noise to cover conversations)③Your device displays "no signal" or is located
Q: Are GPS jammers legal?
A: Laws vary by country. In the US and Europe, using GPS jammers in public areas is often restricted.This device is only for use by approved professional organizations in legal scenarios. Purchasers must confirm the regulations of their country/region and assume full responsibility.
Q: Does the display of "GPS signal weak" on the phone mean that the jamming is successful?
A: Not completely, you need to observe that there is no star count refresh for more than 10 seconds.
Q: Can a GPS jammer block all signals?
A: GPS jammers cannot block all signals. Different GPS jammers are designed to block specific frequencies, primarily targeting GPS tracking systems. However, their effectiveness depends on power output, frequency range, and environmental factors. Professional-grade devices can block 5-8 bands simultaneously, but have technical blind spots for new encrypted signals such as Starlink/5G mmWave.
GPS jammers only block specific GPS frequencies: Most GPS jammers focus on L1 (1575.42 MHz) and L2 (1227.60 MHz) used by commercial and military GPS systems. Some high-end models may also jam L5 (1176.45 MHz) used for advanced navigation.
Won't block all communication signals: GPS jammers generally don't block Wi-Fi, Bluetooth, 4G/5G cellular networks, or radio signals unless they are multi-band jammers that target multiple frequencies.
