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). [191] The two satellites, "MicroSat-1a" and "MicroSat-1b" were meant to be launched together as secondary payloads on one of the Iridium-NEXT flights, but they were instead used for ground-based tests.[192]. [62]​, Los MicroSat 1a y 1b estaban originalmente programados para ser lanzados en órbitas circulares de 625 km con una inclinación de aproximadamente 86,4 grados, e iban a incluir videocámaras pancromáticas para filmar imágenes de la Tierra.[63]​. [40], In May 2018, SpaceX expected the total cost of development and buildout of the constellation to approach US$10 billion. [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. [21]​, Se espera que los satélites de comunicación de Internet sean de clase pequeña, entre 100 y 500 kg de masa, que inicialmente estaban destinados a estar en órbita baja a una altitud de aproximadamente 1.100 kilómetros. 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. The generation 2 Starlink constellation is expected to include up to 30,000 satellites and provide complete global coverage. More recent satellites have visors to block sunlight from reflecting from parts of the satellite to reduce its albedo further. The hardware for Starlink is priced at $649, shipping costs $65, taxes come to $92 and the service costs $129 per month. [31]​ [8], Product development began in 2015. An Expert Answers. Tercer conjunto de 60 satélites operacionales para la red de banda ancha de SpaceX Starlink. A mediano plazo, la compañía espera que Starlink genere ingresos que serían útiles para financiar el proyecto de transporte de Marte. [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. At the time, the Seattle-area office planned to initially hire approximately 60 engineers, and potentially 1000 people by 2018. [68]​ Messier, Doug (3 de marzo de 2017 fechaacceso=27 de diciembre de 2018). Los primeros 1584 satélites son desplegados en 24 planos orbitales de 66 satélites cada uno, con un ángulo mínimo de emisión de señal mejorado (de 40 a 25 grados), respecto a las otras 2 capas orbitales. SpaceX’s Starlink satellite internet service is live and available in a limited beta in some regions, including places in Canada.For the moment, it doesn’t work on the move — the beta sign-up forms clearly state that Starlink is limited to the location users enter at checkout. 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. Según las presentaciones ante la FCC[64]​ estaban destinados a elevarse a una órbita de 1125 km, la altitud operativa para parte de los satélites StarLink. At the time of the June 2015 announcement, SpaceX had stated plans to launch the first two demonstration satellites in 2016,[25] but the target date was subsequently moved out to 2018. [34], By the end of June 2019, SpaceX had communicated with all 60 satellites but lost contact with three; the remaining 57 worked as intended. [49]​, Los satélites serían producidos en masa, a un costo por unidad de capacidad mucho menor que los satélites existentes. Estos incluyen, Segundo lote de 60 satélites, uno de los cuales está provisto de un recubrimiento especial para reducir su reflectividad; esto, de manera experimental para buscar una forma de no perjudicar la observación del cielo desde. [215], SpaceX representatives and Musk have claimed that the satellites will have minimal impact, being easily mitigated by pixel masking and image stacking. This page was last edited on 5 May 2021, at 15:24. [62], In October 2020, SpaceX stated plans to deorbit all 60 prototype v0.9 satellites for "on-orbit debris mitigation". 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. Kang, Cecilia; Davenport, Christian (9 de junio de 2015). The remaining two satellites were intended to be quickly removed from orbit and re-enter the atmosphere in order to test the satellite de-orbiting process; the three that lost contact were also expected to re-enter, but will do so passively from atmospheric drag as SpaceX was no longer able to actively control them. [48] SpaceX said they will meet the deadline of having half the constellation "in orbit within six years of authorization... and the full system in nine years". [citation needed], In April 2020, SpaceX modified the architecture of the Starlink network. Sin embargo, SpaceX finalmente decidió mantener los satélites a un nivel relativamente más bajo, a 550 kilómetros, debido a preocupaciones sobre la contaminación espacial. Contains all v0.9 and higher satellite generations. [61] SpaceX is producing approximately 120 satellites a month. [20] The company operated in 2,800 m2 (30,000 sq ft) of leased space by late 2016, and by January 2017 had taken on a 2,800 m2 (30,000 sq ft) second facility, both in Redmond. In December 2018, the U.S. Air Force issued a US$28 million contract for specific test services on Starlink. [182] The antenna is known internally as "Dishy McFlatface". En agosto de 2019, SpaceX planeaba efectuar 4 lanzamientos durante el resto del año[72]​ y al menos 9 lanzamientos durante 2020. 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. [7], By October 2016, SpaceX had developed the initial satellites that they hoped to launch and test in 2017, but the satellite division was focusing on a significant business challenge of achieving a sufficiently low-cost design for the user equipment, aiming for something that ostensibly can be installed easily at end-user premises for approximately US$200. [70]​, El 23 de mayo de 2019, se lanzaron los primeros 60 satélites de producción completa de la constelación.[10]​. "[225], On 17 April 2020, SpaceX wrote in a Federal Communications Commission (FCC) filing that it would test new methods of mitigating light pollution, and also provide access to satellite tracking data for astronomers to "better coordinate their observations with our satellites". El regulador internacional, la Unión Internacional de Telecomunicaciones, propuso a mediados de 2017 unas directrices internacionales que serían considerablemente menos restrictivas. [30], The first two test satellites built were not flown but were used in ground testing. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion. It ignited conversations about the ethics of a single company unilaterally changing the night sky’s appearance. [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. Early designs had all phase 1 satellites in altitudes of around 1100–1300 km. In the event, the first large deployment of 60 satellites in May 2019 were 227 kg (500 lb)[99] and SpaceX decided to place the satellites at a relatively low 550 km (340 mi), due to concerns about the space environment. [58], In June 2020, SpaceX applied in the United States for use of the E-band in the Gen2 constellation. [46]​ Los planes iniciales a partir de enero de 2015 consistían en que la constelación estuviera compuesta por aproximadamente 4000 satélites,[40]​ más del doble del total de satélites operativos que estaban en órbita a enero de 2015. [15]​, Para enero de 2016, la compañía planeaba tener dos prototipos de satélites volando ese año,[16]​ y tener la constelación inicial de satélites en órbita y operativa aproximadamente en 2020. [181] Photographs of the customer antennas began to be seen on the internet in June 2020, supporting earlier statements by SpaceX CEO Musk that the terminals would look like a "UFO on a stick. How these versions differ from v1.0 has not been made public as of March 2021[update]. [13]​ En octubre del mismo año había 45 ofertas de trabajo abiertas. [6]​ En noviembre de 2018, la empresa recibió la autorización del ente gubernamental estadounidense (FCC) para desplegar 7.518 satélites de banda ancha, que se sumarían a los 4.425 aprobados en marzo del mismo año.[7]​. [26]​ En septiembre de 2017, tanto Boeing como SpaceX solicitaron a la FCC de EE. [223][224] Despite these measures, astronomers found that the satellites were still too bright thus making DarkSat essentially a "dead end. Como contraparte, al disminuir su reflectividad, las características de disipación térmica del satélite se verán perjudicadas a cierto nivel, por lo que notó que serán «pruebas de ensayo y error, pero eventualmente lo solucionarán». Starlink, which costs $99 per month after a $500 setup fee, currently relies on a network of more than 1,400 satellites, but SpaceX wants to deploy as many as 30,000.

[117] On 27 April 2020, Musk announced that the company would introduce a new sunshade designed to reduce the brightness of Starlink satellites. [26], In March 2017, SpaceX filed plans with the FCC to field a second orbital shell of more than 7,500 "V-band satellites in non-geosynchronous orbits to provide communications services" in an electromagnetic spectrum that has not previously been heavily employed for commercial communications services. [24]​ SpaceX plans to launch another 7,500 V-band satellites into orbits around 345 km (214 mi). the company intended to utilize the little-used V-band of the, they intended to use a new orbital regime, the, Second shell: 1,440 in a 540 km (340 mi) shell at 53.2° inclination, Third shell: 720 in a 570 km (350 mi) shell at 70° inclination, Fourth shell: 336 in a 560 km (350 mi) shell at 97.6°, Fifth shell: 172 satellites in a 560 km (350 mi) shell at 97.6°, Total satellites launched (4 May 2021): 1565, Total satellites deorbited (19 January 2021): 67, Total satellites currently in orbit (4 May 2021): 1498, Flat-panel design with multiple high-throughput antennas and a single, 95% of "all components of this design will quickly, 100% of "all components of this design will quickly burn in Earth's atmosphere at the end of each satellite's lifecycle", One of them, numbered 1130 and called DarkSat, had its. Tight fit.», «Much will likely go wrong on 1st mission. [59], By June 2020, SpaceX had filed with Canadian regulatory authorities for a license to offer Starlink high-speed Internet services in Canada. [23] SpaceX job listings indicated the Irvine office would include signal processing, RFIC, and ASIC development for the satellite program. El 6 de diciembre de 2019, en una conferencia de prensa, la presidente de SpaceX, Gwynne Shotwell declaró que «desea que la gente admire los satélites de Starlink, sin perderse la Luna o el resto de planetas del Sistema Solar». For example, SpaceX formally requested authorization for Canada in June 2020,[60] the Canadian regulatory authority approved it in November 2020,[67] and SpaceX rolled out service two months later, in January 2021. SpaceX initially requested to lower the first 1584 satellites, and in April 2020 requested to lower all other higher satellite orbits to about 550 km. [16], Astronomers have raised concerns about the constellations’ effect on ground-based astronomy and how the satellites will add to an already jammed orbital environment. Starlink es una empresa que nació como proyecto de SpaceX para la creación de una constelación de satélites de internet [1] con el objetivo de brindar un servicio de internet de banda ancha, baja latencia y cobertura mundial a bajo costo.
