北斗卫星导航系统工程总设计师杨长风介绍称,此次发射的卫星是北斗三号系统第20颗组网卫星,属于北斗三号系统首颗倾斜地球同步轨道卫星。这种包含倾斜地球同步轨道、地球同步轨道、中圆地球轨道三种不同类型轨道卫星的混合星座设计是北斗系统独有、国际首创,将有效增加亚太地区卫星可见数,为亚太地区提供更优质服务。

这次发射是2019年度北斗导航卫星首次发射,拉开了今年北斗高密度组网的序幕。今年计划发射8-10颗北斗三号组网卫星,完成所有中圆地球轨道卫星发射,进一步完善全球系统星座布局,全面提升系统服务性能和用户体验。

自去年底北斗三号工程建成基本系统、开通全球服务以来,北斗系统运行平稳,经全球范围测试评估,在全球区域定位精度优于10米,在亚太区域定位精度优于5米,满足指标要求。

杨长风表示,经过多年发展,北斗已形成完整产业链,在中国交通、农业、公安、测绘等行业以及大众领域已实现规模化应用。今年,将逐步加大与互联网、大数据、人工智能等新兴技术的深度创新融合,不断催生“北斗+”融合应用新模式和新业态。据统计,截至2018年底,国产北斗导航型芯片模块等基础产品销量已突破7000万片,国产高精度板卡和天线销量分别占国内市场份额的30%和90%。

目前,北斗系统在印度尼西亚土地确权、科威特建筑施工、乌干达国土测绘、缅甸精准农业、马尔代夫海上打桩、柬埔寨无人机、泰国仓储物流、巴基斯坦机场授时以及俄罗斯电力巡检等领域得到广泛应用。北斗高精度产品出口90多个国家和地区,北斗地基增强技术和产品成体系输出海外。

用于执行第100次发射任务的长征三号乙运载火箭由中国航天科技集团一院抓总研制,此次发射的北斗三号系统首颗倾斜地球同步轨道卫星由中国航天科技集团五院抓总研制。后续,该卫星将变轨进入工作轨道,并进行一系列在轨测试,将与此前发射的18颗中圆地球轨道卫星和1颗地球同步轨道卫星进行组网,提供服务。(完)

Scholz pledges support for stronger Europe during first trip abroad as German chancellor******

AFP。

New German Chancellor Olaf Scholz gives a press conference with NATO Secretary General after their bilateral meeting at the NATO headquarters in Brussels on December 10, 2021.。

After a long day of discussions in Paris and Brussels on Friday, new German Chancellor Olaf Scholz said his country is ready to work closely with the European Union and other member states to make Europe "strong and sovereign."

Scholz, who was sworn in on Wednesday as the successor of Angela Merkel, followed in his predecessor's footsteps in making France the first stop during his first-ever trip abroad as chancellor.。

During his meeting with French President Emmanuel Macron, Scholz pledged to work with France on the major challenges confronting the EU. The two leaders discussed the future of the EU with regard to immigration, new sources of energy, border protection and relations with third countries.。

Macron told a press conference after the meeting that he had seen "a convergence of views, a desire to have our countries work together, and a firm and determined belief in Europe, which I knew already, which we will need in the months and years ahead."

Scholz said their talks focused on "making Europe strong and sovereign" in terms of economy, security, and foreign policy. "What is important there is that we work together," he said.。

The meeting took place a day after Macron had laid out the agenda for a "Europe that is powerful in the world" during France's turn as the rotating president of the 27-member Council of the European Union in the first half of 2022.。

Stonger Europe, multipolar world。

Then the chancellor arrived in Brussels, where he met with European Commission President Ursula von der Leyen, European Council President Charles Michel and NATO Secretary-General Jens Stoltenberg.。

At a joint press conference with von der Leyen, Scholz emphasized the importance of strengthening the EU's security and defense policy. He also spoke about his vision of a "strong, sovereign European Union" that will be able to respond to foreign policy challenges in a coordinated way. "Any threat against any EU country will not be tolerated," he stressed.。

Scholz leads a coalition of his Social Democratic Party (SPD), the Free Democratic Party (FDP) and the Greens. The German government works together in a united way, he said. "All three parties are pro-European," he said.。

Germany, as one of the strongest economies in the EU, bears the responsibility to take the role to ensure progress and a bright future in Europe, the chancellor said.。

Von der Leyen, a German politician herself, said Germany played an important role in shaping the EU. "The European Commission is ready for intensive cooperation with the new German government," she said, highlighting the fight against the fourth wave of the COVID-19 pandemic, climate action in the framework of the European Green Deal, and large-scale digitalization as key areas for cooperation between the European Commission and Germany.。

At another press conference with European Council President Charles Michel, Scholz stressed that the EU should live peacefully with other countries when it seeks strategic sovereignty in the multipolar world of today.。

The world will not be bipolar as some people speculate, but a multipolar one with "many powers," including the United States, Russia, China, Japan, India as well as many other rising economies, he said.。

The former German finance minister and vice-chancellor in the Merkel government won 395 of the 707 votes cast in the Bundestag lower house on Wednesday, and pledged broad "continuity" with Merkel's policies while striving to make Germany greener and fairer.。

China's central bank injects liquidity into market******

BEIJING, Dec. 15 (Xinhua) -- China's central bank pumped cash into the financial system through open market operations Wednesday to maintain liquidity in the market.。

A total of 500 billion yuan (about 78.47 billion U.S. dollars) was injected into the market via medium-term lending facility (MLF), according to the People's Bank of China, the central bank.。

The funds will mature in one year at an interest rate of 2.95 percent.。

Meanwhile, the central bank injected 10 billion yuan into the market through seven-day reverse repos at an interest rate of 2.2 percent.。

The move was intended to maintain reasonable and ample liquidity in the banking system, the central bank said.。

The MLF tool was introduced in 2014 to help commercial and policy banks maintain liquidity by allowing them to borrow from the central bank using securities as collateral.。

A reverse repo is a process in which the central bank purchases securities from commercial banks through bidding, with an agreement to sell them back in the future.。

China pursues a prudent monetary policy in a more flexible and appropriate way, according to this year's government work report. Enditem。

The exchange adopts the registration-based initial public offering system, in line with the Nasdaq-style sci-tech innovation board, also known as the STAR market on the Shanghai Stock Exchange, and the tech-heavy ChiNext market on the Shenzhen Stock Exchange. Enditem。
