Starlink is a network of satellites that provide internet. It is being built by SpaceX, Elon Musk's aerospace company. SpaceX first Starlink mission was launched on 24may,2019. It is carry 60 satellites. Now over,800 Starlink satellites are operating at 550km above the earth surface in low earth orbit. Each Starlink satellite is compactly designed and weight is 260kg. It is equipped with four-phased array antennas, single solar array, ion propulsion system, navigation sensors, and debris tracking system. An internet signal sent from the earth is received by one of the Starlink satellites. It then communicates with other satellites in the network using laser light. Once the signal reaches the most ideally located satellite, it is relayed to the ground receiver. At any given time, a starlink satellite is connected with four other satellites in the mega-constellation. The phased array antennas allow satellites to transfer huge amount of data in the short period of time. The in-built navigation sensors provide altitude information to the satellites for precision internet data transfer. The ion thrusters, help the satellites move to orbit, maneuvers in space, and de-orbit at the end of their life. the inputs from the debris tracking system helps them perform maneuvers to avoid collisions with space debris and other spacecraft. As the Starlink satellites orbit in low earth orbit, they are much closer to the ground receivers. It significantly reduces latency during data transfer process. On the down-side, more number of satellites are required to have an extensive coverage. Starlink aims to deliver high speed, low latency internet, including in remote areas where connectivity is limited or completely unavailable.
