The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite, providing reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is ...
The transmission of information between the earth and spacecraft, between two or more points on the earth via spacecraft or using artificial means located in space (a belt of needles, a cloud of ionized particles, and so on), and between two or more spacecraft.
Advanced Mobile Location (AML) is a free-of-charge emergency location-based service (LBS) available on smartphones that, when a caller dials the local (in country) short dial emergency telephone number, sends the best available geolocation of the caller to a dedicated end-point, usually a Public Safety Answering Point, making the location of ...
Media involvement Several reporters for various news agencies located groups of stranded victims, and reported their location via satellite uplink. Authorities, who monitored the network news broadcasts, would then attempt to coordinate rescue efforts based on the news reports.
Laser communication in space is the use of free-space optical communication in outer space. Communication may be fully in space (an inter-satellite laser link) or in a ground-to-satellite or satellite-to-ground application. The main advantage of using laser communications over radio waves is increased bandwidth, enabling the transfer of more data in less time. In outer space, the communication ...
The Jupiter Icy Moons Explorer (Juice, formerly JUICE[3]) is an interplanetary spacecraft developed by the European Space Agency (ESA) and on its way to orbit and study three icy moons of Jupiter: Ganymede, Callisto, and Europa. These planetary-mass moons are planned to be studied because they are thought to have significant bodies of liquid water beneath their frozen surfaces, which would ...
Euclid is a wide-angle space telescope with a 600- megapixel camera to record visible light, a near-infrared spectrometer, and photometer, to determine the redshift of detected galaxies. It was developed by the European Space Agency (ESA) and the Euclid Consortium and was launched on 1 July 2023 from Cape Canaveral in Florida. [10][11] The mission is named after the ancient Greek mathematician ...
GPS signals are broadcast by Global Positioning System satellites to enable satellite navigation. Using these signals, receivers on or near the Earth's surface can determine their Position, Velocity and Time (PVT). The GPS satellite constellation is operated by the 2nd Space Operations Squadron (2SOPS) of Space Delta 8, United States Space Force. GPS signals include ranging signals, which are ...
