#SpaceX #Starlink #ElonMusk #SpaceXStarlink #StarlinkLaunch This is the first in a series covering Starlink. On May 23rd, 2019, SpaceX successfully deployed 60 production satellites for its Starlink constellation. Starlink is SpaceX's ambitious plan to provide low latency, high-bandwidth-global broadband internet coverage. Facts: Constellation 1: 4,409 Satellites ~1500 @ 550km Constellation 2: 7,518 Satellites between 335km to 346km The first constellation is a network of just over 4,400 satellites non-geosynchronous orbit satellites using Ka and Ku brand frequencies. Approximately 1,500 of the 4,400 satellites will operate at 550 km. SpaceX had initially planned to operate the 1500 at an altitude of 1,150km but submitted a request to the FCC to modify its orbital altitudes after lessons learned from the launch of its prototype satellites Tintin A and B in February 2018. The new orbital altitude brings the satellites closer to earth allowing for reduced latency or faster connections of up to 15 milliseconds. This is in contrast to measured latencies of around 638milliseconds (Viasat) The remainder of the 4,400 satellites will operate between altitudes of 1,110km to 1,325km. SpaceX also has an additional constellation that of 7518 V-Band satellites that will operate at “very-low-Earth orbit” , at altitudes from 335km to 346km When will Starlink internet be available? 6 more launches of 60 for minor coverage 12 more launches of 60 for moderate coverage Sources: Starlink revisions, Nov 2018 https://www.youtube.com/watch?v=QEIUdMiColU "Delay is Not an Option: Low Latency Routing in Space" http://nrg.cs.ucl.ac.uk/mjh/starlink-draft.pdf My Gear: Microphone - https://www.amazon.com/gp/product/B00N1YPXW2?ie=UTF8
