Starlink is a satellite internet constellation program operated by SpaceX providing satellite Internet access to most of the Earth. The constellation consists of over 1600 satellites in mid-2021, and will eventually consist of many thousands of mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. While the technical possibility of satellite internet service covers most of the global population, actual service can be delivered only in countries that have licensed SpaceX to provide service within any specific national jurisdiction. As of November 2021, the beta service offering is available in 20 countries.                                       The deployment of the first 1,440 satellites will be into 72 orbital planes of 20 satellites each, with a requested lower minimum elevation angle of beams to improve reception: 25° rather than the...

Both the aircrafts suck-in air from the front and mix it with the fuel in the Compression-Chamber, then the Exhaust Gases are ejected from the rear which thrusts the aircraft forward. The engines in the VTOL aircrafts can be repositioned vertically and the exhaust is directed downwards and the aircraft is thrusted upwards. VTOL Aircrafts are mainly used for military purposes. Long runways are not needed for the Take-Off and Landing of VTOL Aircrafts. Once in air they can fly at supersonic speeds. The Harrier Jump Jet. 2.) How does Autopilot mode works? Aut...
