The planned launch of two revised test satellites was then moved to 2018. The FCC approved the request in April 2019, giving approval to place nearly 12,000 satellites in three orbital shells: initially approximately 1,600 in a 550 km (340 mi) - altitude shell, and subsequently placing approximately 2,800 Ku- and Ka-band spectrum satellites at 1,150 km (710 mi) and approximately 7,500 V-band satellites at 340 km (210 mi). SpaceX can also have business operation and economic considerations that may make a difference in which countries Starlink service is offered, in which order, and how soon. [186], In 2019, tests by the United States Air Force Research Laboratory (AFRL) demonstrated a 610 Mbit/s data link through Starlink to a Beechcraft C-12 Huron aircraft in flight. At the time, the Seattle-area office planned to initially hire approximately 60 engineers, and potentially 1000 people by 2018. [21] In August 2018, SpaceX consolidated all their Seattle-area operations with a move to a larger three-building facility at Redmond Ridge Corporate Center to support satellite manufacturing in addition to R&D. [8] In mid-2018, SpaceX reorganized the satellite development division in Redmond, and terminated several members of senior management. Two prototype test-flight satellites were launched in February 2018. Starlink is launched in groups of 60 satellites per launch. [57] The FCC approved the application in April 2021. The first so-called VisorSat launched on June 4, 2020, on the seventh operational Starlink launch. Stay up to date with what you want to know. The "Starlink" probes will join an ever-growing network of satellites that will one day beam cheap WiFi to people across the globe. Get it now on Libro.fm using the button below. [226], The large number of satellites employed by Starlink also creates a long-term danger of space debris resulting from placing thousands of satellites in orbit and the risk of causing a satellite collision, potentially triggering a phenomenon known as Kessler syndrome, which is like a pinball effect between all of the satellites on Earth that can cause all of the satellites to become inoperable. [59], By June 2020, SpaceX had filed with Canadian regulatory authorities for a license to offer Starlink high-speed Internet services in Canada. [158], With the initial launch of the first 60 satellites of the operational constellation in 2019, SpaceX indicated that it would require 420 satellites in the constellation to achieve minor broadband coverage of Earth, and 780 of the first circa 1,600 to provide moderate coverage. [229] Early in the program, a near-miss occurred when SpaceX did not move a satellite that had a 1 in 1000 chance of colliding with a European one, ten times higher than ESA's threshold for avoidance maneuvers. [215], SpaceX representatives and Musk have claimed that the satellites will have minimal impact, being easily mitigated by pixel masking and image stacking. Spacecraft Launches Mission Status References . [63] In October 2020, Canada granted a license to work there. [190], MicroSat-1a and MicroSat-1b were originally slated to be launched into 625 km (388 mi) circular orbits at approximately 86.4° inclination, and to include panchromatic video imager cameras to film images of Earth and the satellite. X-37B. Starlink satellite launch causes people in Washington to cry UFO. Since the ninth such launch, on August 7, 2020, all Starlink satellites have been VisorSats. [22], In November 2018, SpaceX received U.S. regulatory approval to deploy 7,518 broadband satellites, in addition to the 4,425 approved earlier. [165][166], The Internet communication satellites were expected to be in the smallsat-class of 100 to 500 kg (220 to 1,100 lb)-mass, and were intended to be in low Earth orbit (LEO) at an altitude of approximately 1,100 km (680 mi), according to early public releases of information in 2015. Early designs had all phase 1 satellites in altitudes of around 1100–1300 km. Each satellite continuously broadcasts a radio signal containing its position and the exact time from a very precise atomic clock on board. [Satellites] will de-orbit by propulsively moving to a disposal orbit from which they will re-enter the Earth's atmosphere within approximately one year after completion of their mission. [25][196], The 60 Starlink v0.9 satellites, launched in May 2019, have the following characteristics:[99], The Starlink v1.0 satellites, launched since November 2019, have the additional following characteristics:[citation needed], SpaceX is preparing for the production of Starlink v1.5 and v2.0 satellites in 2021. The new approval was for the addition of a very-low Earth orbit non-geostationary satellite orbit constellation, consisting of 7,518 satellites operating at altitudes from 335 km (208 mi) to 346 km (215 mi), below the ISS. By 2019, the FCC had ruled that half of the constellation must be in orbit in six years, with the full system in orbit nine years from the date of the license.

[177] However, no details on this have been released as of yet. Sign up for 10 Things in Tech. [230][231], SpaceX was challenged regarding Starlink in February 2021 when the National Rural Electric Cooperative Association (NRECA) pressured the U.S. Federal Communications Commission (FCC) to "actively, and aggressively, and thoughtfully vet" the subsidy applications of SpaceX and other broadband providers. [207], By October 2017, the expectation for large increases in satellite network capacity from emerging lower-altitude broadband constellations caused market players to cancel some planned investments in new geosynchronous orbit broadband communications satellites. SpaceX filed documents in late 2017 with the Federal Communications Commission (FCC) to clarify their space debris mitigation plan, under which the company was to: "...implement an operations plan for the orderly de-orbit of satellites nearing the end of their useful lives (roughly five to seven years) at a rate far faster than is required under international standards. [67], The Federal Communications Commission awarded SpaceX with nearly US$900 million worth of federal subsidies to support rural broadband customers through the company's Starlink satellite Internet network. * 16th April - added March 25th oneweb launch, and starlink launch 25 (24 officially) * 14th April - launch 23 and 24 (22 and 23 using wikipedia numbering) have norad IDs now * 31st March - nearby satellites to your home lat long over the horizon that are sunlit are now shown in yellow. Around 27 October 2019, object 44240 (Starlink 26) was lowered slightly out of the active constellation. Tintin A and Tintin B as test satellites are not included. [56] They plan to launch up to 60 more per Falcon 9 flight, with launches as often as every two weeks in 2021. [159], The initial version of Starlink was limited to working within a few miles of the customers' registered address. SpaceX would need to obtain a separate approval from the International Telecommunication Union (ITU). We need a few more satellite launches to achieve compete coverage & some key software upgrades", "ORDER AND AUTHORIZATION AND ORDER ON RECONSIDERATION", "In April 2020 SpaceX submitted an application asking for approval to relocate shells 2-5 down to altitudes ranging from 540 km to 570 km. Part of Transporter-1 (SmallSat Rideshare Mission 1). The terminals can be mounted anywhere, as long as they can see the sky. The satellites look a little like a chain of fairy lights. The aerospace company asked the FCC to lower the altitude range for 2,814 new Starlink satellites from 1,100-1,300 kilometers to 540-570 kilometers, where 1,584 Starlink … Symbol † indicates failed missions and destroyed vehicles.

[40], In May 2018, SpaceX expected the total cost of development and buildout of the constellation to approach US$10 billion. Musk said, "We're going to try and do for satellites what we've done for rockets". SpaceX plans to launch another 7,500 V-band satellites into orbits around 345 km (214 mi). Because the Starlink satellites can autonomously change their orbits, observations cannot be scheduled to avoid them. 60 Starlink satellites stacked together before deployment on 24 May 2019. Contains all v0.9 and higher satellite generations. À l'origine, le lancement était prévu pour le 30 août, mais, selon le compte Twitter de SpaceX, il a été annulé en raison des « conditions météorologiques défavorables pendant les opérations précédant le vol ». [41] Also in November 2018, SpaceX made new regulatory filings with the U.S. Federal Communications Commission (FCC) to request the ability to alter its previously granted license in order to operate approximately 1,600 of the 4,425 Ka-/Ku-band satellites approved for operation at 1,150 km (710 mi) in a "new lower shell of the constellation" at only 550 km (340 mi)[42] orbital altitude. [182] The antenna is known internally as "Dishy McFlatface". First time the satellites were released in an elliptical orbit (212 × 386 km). Full build-out of the approximately 1,200 km (750 mi) constellation of around 4,440 satellites was not then expected to be completed until 2024. [176] The system will use a peer-to-peer protocol claimed to be "simpler than IPv6", it will also incorporate end-to-end encryption natively.

If you saw a peculiar trail of UFOs in the UK on Monday night, don't be too alarmed — they were probably Starlink satellites. states. An animation of SpaceX’s Starlink satellite constellation. [170] Early satellites are launched without laser links, in October 2019 SpaceX expected satellites with these links to be ready by the end of 2020. There's even a Starlink app for Android and iOS that uses augmented reality to help customers pick the best location and position for their receivers. The table is sortable. Supported by PiShop.US and BuyaPi.CA. Enabled by a constellation of low Earth orbit satellites, Starlink will provide fast, reliable internet to populations with little or no connectivity, including those in rural communities and places where existing services are too expensive or unreliable. Starlink is a satellite constellation development project underway by SpaceX, to develop a low-cost, high-performance satellite bus and requisite customer ground transceivers to implement a new spaceborne Internet communication system. [87], In order to offer satellite services over any nation state, ITU regulations and long-standing international treaties require that landing rights be granted by each country jurisdiction. Instead, it will be linked to flat user terminals the size of a pizza box, which will have phased array antennas and track the satellites. [119] As of 15 October 2020[update], over 200 Starlink satellites have a sunshade. [79], The deployment of the first 1,440 satellites will be into 72 orbital planes of 20 satellites each,[10] with a requested lower minimum elevation angle of beams to improve reception: 25° rather than the 40° of the other two orbital shells. Forty-five satellites had reached their final orbital altitude of 550 km (340 mi), five were still raising their orbits, and another five were undergoing systems checks before they raise their orbits. [69][70][71], SpaceX released a new group of 10 Starlink satellites on 24 January 2021, the first Starlink satellites in polar orbits. First batch of ten satellites launched into a 97.5° polar orbit on 24 January 2021 with lasers for inter-satellite communication, A further 338 laser equipped satellites will launch into polar orbit from, All satellites launched from 2022 are likely to have laser data links, Chantilly, Houston, Seattle, Washington DC. The satellites communicate with three testing ground stations in Washington (state) and California for short-term experiments of less than ten minutes duration, roughly daily. Netherlands-based satellite tracker Marco Langbroek stunned space fans shortly afterwards with a video of dozens of the Starlink satellites soaring overhead. [47], By April 2019, SpaceX was transitioning their satellite efforts from research and development to manufacturing, with the planned first launch of a large group of satellites to orbit, and the clear need to achieve an average launch rate of "44 high-performance, low-cost spacecraft built and launched every month for the next 60 months" to get the 2,200 satellites launched to support their FCC spectrum allocation license assignment.

[152], In early 2015, two space entrepreneurs announced satellite Internet ventures in the same week. Starlink is also bound to face some competition in the coming years from Amazon and other satellite internet providers ready to invest in the technology. [4] Deployment of the constellation was not then projected until "late in this decade or early in the next". The two identical satellites were called MicroSat-2a and MicroSat-2b[193] during development but were renamed Tintin A and Tintin B upon orbital deployment on 22 February 2018.

Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). [154] Nevertheless, internal documents leaked in February 2017 indicated that SpaceX expected more than US$30 billion in revenue by 2025 from its satellite constellation, while revenues from its launch business were expected to reach US$5 billion in the same year. The total number of satellites in the 550 km shell would remain the same, at around 1,600. [212][213][214], On 20 November 2019, the four-meter Blanco telescope of the Cerro Tololo Inter-American Observatory (CTIO) recorded strong signal loss and the appearance of 19 white lines on a DECam shot (left image). Starlink satellites use Hall-effect thrusters with krypton gas as the reaction mass[99][178] for orbit raising and station keeping. ISS. [20][153], After the failures of previous satellite-to-consumer space ventures, satellite industry consultant Roger Rusch said in 2015, "It's highly unlikely that you can make a successful business out of this". [7], The satellites will employ optical inter-satellite links and phased array beam-forming and digital processing technologies in the Ku- and Ka-bands, according to documents filed with the U.S. Federal Communications Commission (FCC).
