[Musk said that restrictions on the use of Ukraine's "Star Shield" are determined by the U.S. government] October 15th, Elon Musk, CEO of the U.S. Space Exploration Technology Corporation, said on social media on the 14th that the "Star Shield" satellite communication system used by Ukraine is owned and controlled by the U.S. government. Any restrictions on the speed or purpose of use are determined by the U.S. military and ultimately depend on the President of the United States. Musk said on social media that day that "Starlink" is a commercial satellite communications service owned and controlled by Space Exploration Technologies Corporation. It is limited to civilian or defensive activities and may not be used for offensive military operations. "Star Shield" is a satellite communication system developed by Space Exploration Technology Corporation for the U.S. government and military. It is different from "Star Link", which mainly provides commercial services, but both use part of the same satellite technology and infrastructure. (Xinhua News Agency)
