Anti-jam antennas are used to provide navigation signals for navigation receivers and are used in complete sets with the receiver. The positioning, speed, and time information output by the receiver are the data ultimately needed by the user.

Global satellite navigation systems include: China's Beidou satellite navigation system, the United States' GPS satellite positioning system, Russia's GLOASS global navigation satellite system, and Europe's GALILEO satellite navigation and positioning system.

Why need Anti-Jam antennas?
The satellite signal reaches the ground very weakly (power ≤ -120dBm), is buried deep in the noise (power is about -100dBm), and is extremely susceptible to interference, causing the receiver to be unable to achieve positioning.

How Anti-Jam Antennas work?
According to the principle of satellite signal acquisition, by reducing the power of the strong interference signal to near the noise power, the satellite signal can be captured and tracked, and the anti-interference goal can be achieved.
