XICHANG, Sichuan, Feb. 12 (Xinhua) -- China sent two satellites into orbit on a single carrier rocket for its domestic BeiDou Navigation Satellite System (BDS) Monday.

The twin satellites, which form a network with four previously launched BeiDou-3 satellites, were the fifth and sixth satellites in the BeiDou-3 family. They entered orbit more than three hours after the launch from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

Китай вывел на орбиту два навигационных спутника "Бэйдоу-3". (Синьхуа)

Сичан /пров. Сычуань/, 12 февраля /Синьхуа/ -- В понедельник Китай с помощью ракеты-носителя "Чанчжэн-3Б" /серия "Великий поход"/ вывел на орбиту два спутника "Бэйдоу-3". Запуск был произведен с космодрома Сичан в юго-западной китайской провинции Сычуань.
Это пятый и шестой спутники "Бэйдоу-3", запущенные Китаем для спутниковой навигационной системы "Бэйдоу".

После более чем трехчасового полета спутники успешно вышли на намеченные орбиты.
С учетом нынешнего запуска китайские ракеты-носители семейства "Чанчжэн" совершили 267 полетов.

К настоящему времени все запуски китайских спутников "Бэйдоу" были совершены с космодрома Сичан, а коэффициент успешности запусков составляет сто процентов, сообщил представитель космодрома Дун Чунцин.

Космодром Сичан был образован в декабре 1970 года и предназначен главным образом для запусков геосинхронных спутников.

Twin BeiDou-3 navigation satellites sent into orbit by single rocket
Source: Xinhua | 2018-02-12 21:21:03 | Editor: Xiang Bo

XICHANG, Sichuan, Feb. 12 (Xinhua) -- China sent two satellites into orbit on a single carrier rocket for its domestic BeiDou Navigation Satellite System (BDS) on Monday.

The twin satellites, which form a network with four previously launched BeiDou-3 satellites, were the fifth and sixth satellites in the BeiDou-3 family. They entered orbit more than three hours after the launch from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

All of the BeiDou satellites were launched from Xichang and all of the missions were successful, said Dong Chongqing, Party secretary of the launch center.

Set up in 1970, Xichang Satellite Launch Center's major task is to launch geostationary satellites. It has launched more satellites than other centers in China.

The twin satellites were carried by the Yuanzheng-1 upper-stage on the rocket. Yuanzheng-1, or Expedition-1, is an independent aircraft installed on the carrier rocket with the ability of sending one or more satellites into different orbits in space.

The launch was the 267th mission for the Long March rocket family.

Спойлер

China will send 18 BeiDou-3 satellites around the end of 2018 with Long March-3A rockets, according to the country's schedule.

Among eight of its 14 planned missions in 2018, the Long March-3A rocket will send twin BeiDou-3 satellites into space, said Cen Zheng, rocket system commander-in-chief of the mission.

"China developed a new generation of platform for navigation satellites that enable a single rocket to send two or more satellites into space in 2010," said Wang Ping, the chief designer of BeiDou-3 family. "The lightweight platform is easy to assemble and versatile, which fits the mission to send satellites on one rocket."

Named after the Chinese term for the Big Dipper, the BeiDou project was formally launched in 1994. It began to serve China in 2000 and the Asia-Pacific region at the end of 2012.

By around 2020, when the BDS goes global, it will have more than 30 satellites.

China adds two more satellites to home-grown navigation network

Two more Chinese Beidou navigation satellites successfully lifted off aboard a Long March 3B rocket Monday on China's seventh space launch in five weeks.

The Long March 3B rocket and a restartable Yuanzheng upper stage deployed the two Beidou navigation satellites — the 28th and 29th to join China's navigation network — nearly four hours after launch from the Xichang space base in Sichuan province, according to Chinese state media reports.

Propelled by 1.3 million pounds of thrust, the Long March 3B rocket lifted off from the Xichang launch base at 0503 GMT (12:03 a.m. EST) Monday.

Four strap-on boosters and a core stage fueled by hydrazine and nitrogen tetroxide fired for around two-and-a-half minutes. The Long March 3B dropped the spent booster tanks over Chinese territory as the rocket flew southeast from Xichang, and the launcher's second stage fell into the South China Sea after completing its burn.

A third stage engine placed the two Beidou satellites and the Yuanzheng upper stage into a preliminary elliptical orbit. The upper stage engine was programmed to place the twin payloads into a circular orbit approximately 13,700 miles (22,000 kilometers) above Earth.

Chinese state media confirmed the launch was a success, and U.S. military tracking data showed the Beidou satellites were orbiting on their planned trajectory inclined 55 degrees to the equator.

The satellites launched Monday are the fifth and sixth members of China's third-generation Beidou fleet, joining four similar craft launched since early November.

Named for the Chinese word for the Big Dipper constellation, the Beidou constellation achieved an initial operating capability with coverage over the Asia-Pacific region in 2012. Development of the Beidou program began in 1994.

The first Beidou test satellite launched in 2000. With Monday's mission, China has launched 29 Beidou navigation payloads into orbit, but not all of them remain operational.

When complete, the Beidou system will join the U.S. Air Force's Global Positioning System, Russia's Glonass satellite network, and Europe's Galileo fleet — which is still being deployed — as the world's four navigation services with global reach.

The third-generation satellites now being launched by China feature higher-performance rubidium and hydrogen atomic clocks, inter-satellite links, improved spatial signal accuracy, better compatibility with other countries' navigation satellites, and offer search-and-rescue services, according to a Chinese government release published on the Beidou program's official website.

Chinese officials aim to have 30 Beidou satellites operational by 2020, enough to offer independent global navigation services.

China's state-run Xinhua news agency reported up to 14 more Beidou satellites are due for launch before the end of 2018.

The completed Beidou constellation will consist of 27 satellites in medium Earth orbits, five in geostationary-type orbits around 22,300 miles (36,800 kilometers) over the equator, and three in inclined geosynchronous orbits that oscillate north and south of the equator.

Monday's flight was the seventh of up to 40 space launches planned by China this year.

Besides further deployments of Beidou satellites, China plans to launch a series of communications and Earth observation payloads for commercial and military users.

China has also scheduled the launch of the Chang'e 4 lunar probe later this year. Chang'e 4 will attempt to make the first landing on the far side of the moon.
