  Satellite operation, launched by foreign suppliers

  Satellite development

 Orbital  launch project at advanced stage or deployment of domestic launch missiles

Although Canada is the third country to build a satellite into space, ^[32] it was launched from a US space airport using a US rocket . The same thing applies to Australia, where they launched the first satellite with the help of a US Redstone rocket and American aid workers, as well as a joint launch facility with the United Kingdom . ^{[33] The} first Italian satellite, San Marco 1, was launched from Wallace Island ( Virginia , USA) on a U.S. Scout rocket on December 19, 1974, with an Italian launch team trained by NASA .

The first attempt to launch satellites [ edit ]

• The United States tried unsuccessfully to launch their first satellite in 1958; They succeeded in 1957.
• China tried unsuccessfully to launch the first satellite in 1979; They were successful in 1970.
• Chile tried unsuccessfully in 1995 to launch their first satellite, Fasat-Alpha, using foreign rockets; They succeeded in 1998.
• North Korea attempted to launch satellites in 1999, 2009, 2012; December 12, 2012 was the first success.
• Libya has been developing its own national libsat satellite project since 1998 to re-launch suspended telecommunications and remote sensing services following the fall of Gaddafi . ^[34]
• Belarus tried unsuccessfully in 2006 to launch the first satellite Belkya with a foreign rocket.

Both Chile and Belarus used Russian companies as the main contractors to build their satellites, they used Russian-Ukrainian rockets and launched from Russia or Kazakhstan.

The first satellite designed [ edit ]

• Armenia founded Armaxmos in 2012 and announced the launch of the first telecommunications satellite, Armsat. About ২৫ 250 million has been invested and the country is selecting contractors between Russia, China and Canada to build the satellite in 4 years. ^[35] [36]

Attack satellites [ edit ]

Militant groups have been hacking satellites since the mid-2000s to disseminate their notifications and steal secret information from military communications networks. ^[36] [36]

Low-altitude orbital satellites have been destroyed by surface-to-air missiles for testing purposes. Russia , the United States , China and India have demonstrated their ability to destroy satellites. ^[39] When the Chinese military destroyed a former meteorological satellite in 2006 , ^[39] in February 2006 the US Navy destroyed a useless reconnaissance satellite. ^[40] On March 26, 2019, India destroyed a direct test satellite at an altitude of 300 km in 3 minutes with a missile. This made India the fourth country to have the ability to destroy satellites directly.^[41] [42]

Jamming [ edit ]

Due to the low power signals received in satellite transmissions, they are at risk of being jammed by ground-based transmitters. The range of these national jamming transmitters is limited to geographical areas, ^[43] [44] but satellite phone and television signals are also being jammed.

Also, a bhusthira satellite carriers interfere with radio signals transferred to the satellite transponder is very easy to be valid. It is very common for a ground satellite to transmit commercial satellite space at the wrong time or to the wrong frequency and to double-illuminate the transponder, rendering the frequency useless. Satellite operators now have sophisticated monitoring that enables them to identify the source of any carrier and effectively manage transponder space. ^{[ Citation needed ]}
