долгое ожидание...

10-05-2022   Компания Maxar Technologies отложила запуск своих первых двух спутников оптической визуализации WorldView Legion на 2-3 месяца, до сентября [2022], из-за неправильно разработанной последовательности испытаний спутников, которая добавит к стоимости программы около 20 миллионов долларов.

New hazard area's have been published, and they reveal that the launch of the WorldView Legion 1 & 2 satellites has been rescheduled for May 1st at 18:30 UTC! This is another 1-week delay.

ждём 20й полёт B1061.

[ОАЯ]

Не смог найти диапазон частот работы спутника. По преемственности выходит C band, а высотомеры в Ka band. Но тогда выходит слишком архивный спутник по радиоканалу.
Еще вопрос V band - это сколько?

[mik73]

Еще вопрос V band - это сколько?

А мы покупаем или продаем?
По IEEE - 40-75ГГц
По ISO (отсутствует в IEEE и ITU-R) выделяется еще Q ( 33 до 50 ГГц), частично пересекающийся с V.
Поэтому может имеься в виду 50-75 ГГц.
В радиорелейках так обычно называют работу на частотах около 60 ГГц. В спуниковой связи примерно тоже.

Airbus outlines plans for future high-resolution imaging satellites
WASHINGTON — More than a year after losing two Pléiades Neo high-resolution imaging satellites in a launch failure, Airbus has outlined plans to replace them.

Спойлер

The company announced April 29 a new program called Pléiades Neo Next, which it described as creating "new satellite assets and capabilities" to augment the two Pléiades Neo satellites currently in operation. That will start with one satellite Airbus has started to manufacture that will launch in the next few years.

"This new program will further enhance our standard of excellence in terms of quality, performance and reliability to deliver images as well as geo-intelligence services and applications," Karen Florschütz, executive vice president for connected intelligence at Airbus Defence and Space, said in a statement.

Airbus currently operates two Pléiades Neo satellites launched in 2021, capable of providing imagery at a resolution of 30 centimeters. Two more satellites were launched in December 2022 but were destroyed in the failure of their Vega C rocket.

The company said for more than a year after the failure that it was exploring how to replace the two lost satellites. At a Feb. 15 briefing about the company's 2023 financial results, Guillaume Faury, chief executive of Airbus, said there was "strong demand" for the imagery produced by the two operational satellites but that the company had not decided how to replace, partially or completely, the capacity on the lost satellites.

The announcement of the Pléiades Neo Next program did not provide many details about the number of additional satellites, beyond the one to be launched in the next few years, as well as their capabilities. The Pléiades Neo Next satellites will offer "enhanced native resolution," Airbus said, but did not give a specific resolution. The company said it will also upgrade its ground segment to improve capacity and reduce the time between requesting and receiving imagery.

Marina Mittermaier, a spokesperson for Airbus Defence and Space, told SpaceNews that the Pléiades Neo Next satellites will provide geolocation accuracy of 3.5 meters. They will provide imagery in red, green and blue as well as near infrared and "deep blue" bands. She declined to disclose financial details about the company's investment in the new system.

[свернуть]

The announcement of Pléiades Neo Next comes as Maxar Intelligence is preparing to deploy its WorldView Legion constellation of imaging satellites. The first two spacecraft of the six-satellite constellation are scheduled to launch as soon as May 2 on a Falcon 9 from Vandenberg Space Force Base in California after lengthy delays. Those satellites, like Pléiades Neo, will be able to collect images with a resolution of 30 centimeters.

SpaceX is targeting Thursday, May 2 for launch of the Maxar 1 mission to orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. The 14-minute window opens at 11:36 a.m. PT. If needed, a backup launch opportunity is available on Friday, May 3 at the same time.

A live webcast of this mission will begin on X @SpaceX about 15 minutes prior to liftoff. Watch live.

This will be the 20th flight for the Falcon 9 first stage booster supporting this mission, which previously launched Crew-1, Crew-2, SXM-8, CRS-23, IXPE, Transporter-4, Transporter-5, Globalstar FM15, ISI EROS C-3, Korea 425, and nine Starlink missions. After stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base...

ПН - два спутника для наблюдения Земли следующего поколения WorldView Legion 1 & 2 компании DigitalGlobe общей массой 1500 кг.
Спутники созданы компанией Maxar и имеют на борту телескоп 30-сантиметрового класса с новой технологией фокальной плоскости. Данные, собранные аппаратами, будут использоваться в сфере безопасности на море, в т.ч. для наблюдения за стихийными бедствиями, загрязнением окружающей среды, разливами нефти, для обнаружения незаконного рыболовства, пиратства и контрабанды. Используя алгоритмы искусственного интеллекта, они смогут самостоятельно идентифицировать подозрительную деятельность и делать снимки с большим количеством посещений одного и того же района Земли каждый день.
Запуск аппаратов планировался на ракете Falcon 9 ещё в 2018 году, но много раз переносился из-за неготовности полезной нагрузки. Развёртывание спутников на солнечно-синхронной орбите высотой 500 км состоится через 13 и 16 минут после старта. Срок службы спутников составит не менее 10 лет.
