SATELLITE JAMMER
SATELLITE JAMMERS
Stratign’s Satellite Jammers allow jamming of satellite signals in the Downlink or Uplink bands disabling communications in the L, C, X, Ka and Ku bands.
Most communication satellites are placed in geostationary orbit (GEO). This is a circular orbit in Earth’s equatorial plane. The orbit is located approximately 22,300 miles above the equator and from Earth these satellites appear to be located at a stationary point in the sky. This enables the Earth station antennas to be simplified since they are pointed in a fixed direction and do not have to track a moving object.
The satellite phone communications are based on C-band for the link to earth station/gateway stations and L-band for the link to the satellite phone handsets. The most desired frequency band for satellite communication systems is 6 GHz on the uplink (Earth to satellite transmission) and 4 GHz on the downlink (satellite to Earth transmission) which is the C-band. Newer satellites operate Ku-band which use 14 GHz on the uplink and 12 GHz on the downlink with orbital spacing of 2 degrees. Ku-band provides greater band width for satellite transmission and has smaller footprint on the Earth which enables greater frequency re-use. Ku-band has grown more popular for use by VSAT networks and Satellite TV DTH operators due to reduced size of antennas and lower cost of subscriber equipment. Although the Ku-band suffers from greater losses due to rain attenuation but recent developments of higher power output of satellites in this band has given greater possibilities for usage of this band. Certain satellites make use of X-band or Ka band for their communication.
Jamming the satellite phones or the satellite trunks in a particular region are achieved by jamming the downlink signals in the L, C, X, Ku and Ka bands. The Stratign downlink jammers are effective for approximately 20 kms range. However, there may be a need to jam the uplink signals on any particular channel to render the communication on those channels ineffective thereby taking down a complete network. Stratign uplink jammers are designed to target at least 2 channels on each band simultaneously.
