Starlink, the project Elon Musk which consists of the development of a global network of broadband and high-speed internet to places where access has been difficult, uses satellites located 550 kilometers which, unlike others at a greater distance from Earth, transmit information faster.
Starlink satellites they deorbit themselves at the end of their useful lives and burn up in the Earth’s atmosphere in a period of one to five years; They have four very powerful antennas that give them great performance capabilities and can be quickly redirected.
These devices are made up of solar panels and propulsion systems powered by krypton. In addition, they have a sensor that detects debris to avoid colliding with them.
These nanosatellites are located at a low Earth orbit so that the connection arrives much faster. To send their signal they need the propagation of electromagnetic waves.
One of the advantages of using satellites is that the construction of infrastructure is avoided.such as cables or towers.
SpaceX’s goal is to deploy some 30,000 satellites between 100 and 500 kg in mass. In 2019 the first 60 were launched and currently there are said to be about 2,400 orbiting the Earth.
Total connectivity is what is intended with satellite internet connections in the world
The satellite service could provide internet to 90% of homes in Ecuador
Velocity
Starlink users need a kit, configured for a certain geographical area, which receives the signals through an antenna included in the package. The signals will travel to the router that is installed at home to be able to use the internet.
Starlink’s basic plan promises a speed of satellite connection at a speed between 50 and 250 Mbpswith a latency between 20 and 40 milliseconds.
The Premium plan, meanwhile, promises speeds of 150Mbps to 500Mbps, with the same latency. Although there are brief periods without connectivity, the company assures that this will improve as its satellite network increases.
A second version of Starlink will arrive in 2023, which will be able to transmit directly to the mobile phones of its users, eliminating “dead zones” around the world. (YO)
