WebThere are two main types of satellite jamming. The first, uplink jamming, interferes with the signal going from a ground station or user terminal to the satellite. An RF signal of the same frequency as the targeted uplink signal is transmitted to the satellite, aiming to limit the satellite transponder from differentiating between the jamming Radio jamming is the deliberate jamming, blocking or interference with wireless communications. In some cases, jammers work by the transmission of radio signals that disrupt communications by decreasing the signal-to-noise ratio.
