What is Starlink
Starlink is a satellite internet service provided by SpaceX, a private American aerospace manufacturer and space transportation services company founded by entrepreneur Elon Musk. The service uses a network of thousands of low-Earth orbit satellites to provide high-speed internet access to areas of the world where access to the internet is limited or non-existent. This includes rural and remote areas, as well as areas where traditional wired or wireless internet infrastructure is not cost-effective or logistically feasible to install.
The Starlink system is composed of three main parts: the satellites in orbit, the user terminal on the ground, and the network of ground stations that communicate with the satellites and control their movements in orbit. The user terminal is a small, flat, weather-resistant device that is easy to install and is capable of providing high-speed internet access to a single location.
The Starlink service is currently in beta testing and is available in select areas of the United States, Canada, and the United Kingdom. SpaceX has plans to expand coverage to more countries in the future. The main purpose of Starlink is to provide high-speed internet access to areas where access is limited or non-existent, as well as to bridge the digital divide between urban and rural areas.
Satellite Specifications
The Starlink satellites are small, flat-panel design, each weighing about 227 kg and measuring about 1.2 meters across. They are equipped with solar panels to generate power, and use Ku-band radio frequencies to transmit and receive internet data. The satellites are in low-Earth orbit, at an altitude of about 550 km, which allows for lower latency and faster internet speeds than traditional geostationary satellites. They are controlled by a network of ground stations, which are used to communicate with the satellites and direct their movements in orbit.
The satellites are built to be quickly and easily replaced, with the goal of minimizing downtime. They are also designed to be highly maneuverable, which allows them to adjust their orbits to avoid collisions with other objects in space, and to be deorbited at the end of their operational life.
The Starlink system is using a phased array beamforming antenna on the user terminal to communicate with the satellite and deliver the internet. The user terminal is a small, flat, weather-resistant device that is easy to install and is capable of providing high-speed internet access to a single location.
Overall, the Starlink satellite system was designed to be highly scalable, reliable and cost-effective, allowing it to provide internet access to even the most remote locations on Earth.

Satellite train
It is curious to release that large number of satellites simultaneously in space, which will cause the so-called train of satellites or Starlink train. In it, for several days after being put into orbit, the satellites go in a row one after another at a close distance, being visible from certain points on the globe depending on the orbit chosen.
Some Portals also explain to us how to see this famous and spectacular Starlink train from our location. It is worth it that you take a look and keep an eye on the day of the launches so as not to miss this artificial phenomenon soaring through the skies. For this, there are many Android applications for Smartphone that tell you how and when they pass through your area so that you are prepared. These are concentrated for now in the northern hemisphere coinciding with the US, Canada and Europe.
Starlink availability and speed
Starlink is currently in beta testing and is available in select areas of the United States, Canada, and the United Kingdom. SpaceX has plans to expand coverage to more countries in the future.
As for the speed, Starlink’s advertised download speeds are between 50 and 150 Mbps, with upload speeds of around 20 Mbps.
