 FB secret satellite network plan exposure to challenge SpaceX/OneWeb


Figure 1:Facebook shows plans, and satellites provide Internet services for computers on the planet. The document disclosed a stealth company called PointViewTechLLC, which is investing millions of dollars in developing experimental satellites. The satellite, named Athena, will transmit data faster than SpaceXs Starlink satellite network 10 times faster than SpaceXs first Starlink satellite launched in February. However, PointView seems to be on paper only. In fact, the small company seems to be a new subsidiary of Facebook. It was set up in 2017 with the aim of ensuring the secret of Facebooks storm plan. Many technology companies believe that the future of the Internet needs to rely on orbit. About half of the people on the planet lack broadband Internet connections, especially those living in rural areas and developing countries. The goal of SpaceX is to send nearly 12 thousand tarlink satellites to LEO, providing Gigabit speed Internet services for most parts of the earths surface. SpaceXs rival, OneWeb, has been funded by SoftBank, Qualcomm, and VirginGroup of British tycoon Richard Branden (RichardBranson), which plans to use about 2500 LEO satellites for similar global network coverage. In early 2019, PointViews Athena will also be equipped with ArianespaceVega launch vehicle to be sent to near earth orbit. The size and weight of the Athena (150 kg) is similar to the SpaceX and OneWeb satellites, but it will use a high frequency millimeter wave radio signal to ensure faster data transmission rates. PointView estimates that the transmission speed of its electronic band (E-band) system will reach 10000 trillion per second. The purpose of PointView is to understand whether the use of electronic band systems can be used to provide fixed and mobile broadband access services for areas lacking or without network services, the company said in an application document. The US - based space companies have to get FCC permission before launching, and often start building satellites and ground stations before they submit written documents. PointView said in its application: as early as July 2016, PointView had informed FCC to start building satellite facilities. However, according to the records of Delaware, the company was registered in April 2017. PointView did not submit annual reports, nor did it disclose the identity of directors or shareholders. In contrast, in California, the clue points to Facebook. First, PointView has the same agency services in Delaware as other Facebook subsidiaries, including the FCLTech company that manages its early connection tests. PointViews application to FCC was also represented by the law firm in Washington, D.C., and even the same lawyer, who had previously provided assistance to the FCC for Facebook. Figure 2: this graph shows the path (red) of the Athena satellite, the area it can be connected to (yellow), and the area where it can send network data (green). In its application, PointView confirmed the location of three ground stations, which can transmit data to Athena on orbit, and also receive data transmitted by Athena. One of the ground stations is the so-called satellite transmission port near Ventura (Ventura) in California, and many satellite companies share it. The second ground station is located at the Wilson Observatory in Losangeles (MountWilsonObservatory), another hot spot for communication hardware. As for the third ground stations, it is described in the application as a place for resettlement of spare antennas, located in an anonymous commercial park in the Northridge area of the city. According to reports, Facebook rented 7432 square meters of office space here in October last year and is currently undergoing renovation. Facebook is currently recruiting three vacancies for its Northridge office, all of which are related to communication and connectivity. For example, Extra-Terrestrial product manager is expected to have rich knowledge of satellite and millimeter wave communication systems. At present, a Facebook employees personal data on LinkedIn shows that he is working on the design and development of the millimeter wave communication product. Facebook did not respond to requests from reporters for comment, but the company has always been interested in millimeter wave systems. As early as 2015, FCLTech submitted an application to FCC in the hope of using UAV in Losangeles and its vicinity to test the potential communication capabilities of the electronic band. In 2016, Facebook and its global Internet company Internet.org announced that the first test flight of the high altitude solar UAV Aquila using electronic band technology was first tested, and the test had not stopped in 2017. Facebook has also been considering the satellite network program. In its letter to FCC in 2016, the company wrote: Facebook is aware of the important role of satellites in improving and expanding network connectivity. In remote and sparsely populated areas, there is a huge gap in infrastructure, and the economic barriers to infrastructure installation are much higher, and satellite services may provide the most effective way of connection. Figure 3:Athena will be made by SSL, a satellite company, based on its SSL-100 design. PointView expects downloading speed at its ground station to be about 10Gbps, and its uplink speed is more than 30Gbps. However, because Athena is located in low earth orbit, it only flies over three ground stations a few times a day, which lasts for less than 8 minutes each time. If Facebook really wants to provide global connectivity services, it needs to replicate plans for SpaceX and OneWeb, while deploying thousands of satellites on the orbit. This may cause FCCs concern, which attaches great importance to the risk of orbital collision. If FCC does not agree to send more Facebook satellites into the near earth orbit, this will not be the first of ElonMusk (ElonMusk) to defeat the Mark Zuckerberg (MarkZuckerberg) orbital Internet program. In 2016, a Internet.org satellite designed to provide Internet coverage for Africa was destroyed when its SpaceX rocket exploded at Cape Canaveral. In view of this, no matter who is behind the scenes of PointView, they hope that there will be less noticeable launch.
