OneWeb
is competitor to the SpaceX Starlink satellite system. OneWeb successfully
launched 6 test satellites and plans a February 7, 2020 Soyuz launch of its
first 34 commercial satellites.
OneWeb plans a 600 satellite system with 48 spare satellites.
OneWeb would need 18 successful Soyuz launches to deploy their satellites. The
first launch was already delayed from November 2019. They have ordered 21 Soyuz
launches from Arianespace. They hope to get all the satellites up by the end of
2021.
OneWeb is around one year behind SpaceX. SpaceX now has 180
production satellites in orbit. SpaceX is four successful launches from a
minimum coverage system and ten from moderate coverage. SpaceX should have
minimum coverage by April 2020 and moderate coverage by the middle of 2020.
SpaceX should have full 1600 phase 1 coverage around the first quarter of 2021.
The satellites in the OneWeb constellation are approximately 150
kg (330 lb) in mass. The OneWeb satellites will be 18 polar orbit planes at
1,200 kilometers (750 mi) altitude.
The SpaceX Starlink satellites are in 500-550 kilometer orbits.
The satellites will operate in the Ku band, communicating in the
microwave range of frequencies in the 12–18 GHz portion of the electromagnetic
spectrum. The user terminal antenna on the ground will be a phased array
antenna measuring approximately 36 by 16 centimeters (14.2 by 6.3 in) and will
provide Internet access at 50 megabits/second downlink bandwidth.
In 2015, Samsung announced a 4600-satellite constellation orbiting
at 1,400 kilometers (900 mi) that would have 200 gigabytes per month of
internet data for the total system. Amazon announced a large broadband internet
satellite constellation in April 2019, planning to launch 3,236 satellites in
the next decade. Amazon calls it Project Kuiper.
Samsung and Amazon have no launches scheduled.

Comentário: Loucura leitor, uma tremenda e insana corrida tecnológica
que irá no futuro inviabilizar a Astronomia ótica realizada da superfície terrestre.
Essa gente não tem limites e obrigará o desenvolvimento cada vez maior de telescópios
espaciais óticos a serem colocados após a órbita lunar, isto é, se quisermos obter
algum resultado significativo nesta área nas próximas décadas. Fora o fato de que
essas constelações poderão dificultar também a trajetória de espaçonaves tripuladas
na órbita da Terra, bem como talvez sondas espaciais que utilizam essa mesma órbita
como um estilingue, visando alcançar assim objetos no espaço profundo. Enfim... Aproveitamos para agradecer ao nosso leitor Rui Botelho pelo envio dessa notícia.
