We have been following the plans of Elon Musk and Greg Wyler to launch constellations of low-earth orbit satellites to provide global Internet service and fast long-distance links. Neither company plans to be in operation for several years, but Musk's SpaceX is ready to test two satellites.
SpaceX has filed an application to launch two test satellites and satellite experts have been discussing it on Reddit.
The application calls for launching two identical Ku-band downlink satellites (cubesats?), which will orbit at 625 kilometers and have an expected lifetime of 6-12 months. The objective of the launch is:
To validate the design of a broadband antenna communications platform (primary payload) that will lead to the final LEO constellation design using three broadband array test ground stations positioned along the western coast of the US.They will do broadband array testing using a network of three broadband test ground locations at SpaceX Headquarters in Hawthorne, California, Tesla Motors Headquarters in Fremont, California and SpaceX Washington in Redmond, Washington. (It pays to own multiple companies). Two types of ground terminal will be evaluated at each location.
These test results will lead to a revised, perhaps final version of the satellites and ground stations. I've no idea how soon they might be ready for operation, but SpaceX is first out of the gate in the satellite constellation Internet service race.
Elon Musk wants to go slowly on the SpaceX satellite Internet project:
Many companies have tried and failed -- we want to be completely sure of success and not overestimate our strengthOneWeb is pushing ahead with Aireanspace planning at least 21 launches between 2017 and 2019.
OneWeb seems to be working with many partners -- OneWeb CEO Greg Wyler is shown below with Stéphane Israël, Chairman and CEO of Arianespace (center) and Richard Branson, founder of Virgin Galactic (right) -- while SpaceX is working on their own satellites and launch vehicles.
