Attacks on satellites

In recent times satellites have been hacked by militant organisations to broadcast propaganda and to pilfer classified information from military communication networks.^[22][23]

Satellites in low earth orbit have been destroyed by ballistic missiles launched from earth. Russia, the United States and China have demonstrated the ability to eliminate satellites.^[24] In 2007 the Chinese military shot down an aging weather satellite,^[24] followed by the US Navy shooting down a defunct spy satellite in February 2008.^[25] Russia and the United States have also shot down satellites during the Cold war.

Jamming

Due to the low received signal strength of satellite transmissions they are prone to jamming by land-based transmitters. Such jamming is limited to the geographical area within the transmitter's range. GPS satellites are potential targets for jamming,^[26][27] but satellite phone and television signals have also been subjected to jamming.
