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)

Economic Watch: China strides toward carbon neutrality amid market******

BEIJING, Oct. 28 (Xinhua) -- China has leveraged policy tools and explored market-oriented mechanisms, including establishing multi-level carbon trading markets and scaling up green financing, to achieve carbon neutrality.

Three months ago, the national carbon market, a major institutional innovation in China, started online trading. As the world's largest carbon trading market in terms of the amount of greenhouse gas emissions covered, it has involved a total of 2,162 power generation companies, representing 4.5 billion tonnes of carbon dioxide emissions.

By the end of September, the trading volume in the market reached 17.65 million tonnes, with a turnover of 801 million yuan (about 125.24 million U.S. dollars), according to a white paper released Wednesday by the State Council Information Office.

In fact, pilot programs on carbon emission trading have already been implemented at local levels before the nationwide carbon markets took shape.

Since 2011, seven pilot trading markets have been established in Beijing, Shanghai, Tianjin, Chongqing and Shenzhen as well as the provinces of Hubei and Guangdong.

Nearly 3,000 major emitters in more than 20 industries, including power, steel and cement, were incorporated in the carbon-trading platforms in 2013.

As of Sept. 30, the total trading volume of the seven pilot carbon trading markets had reached 495 million tonnes of carbon dioxide equivalent, representing a value of approximately 12 billion yuan.

China also established a greenhouse gas voluntary emission reduction program in 2012 to promote the transformation toward low-carbon industrial structure and energy consumption.

By the end of last month, the total trading volume of greenhouse gas voluntary emission reduction had exceeded 334 million tonnes of carbon dioxide equivalent, with the turnover approaching 3 billion yuan.

To tackle climate change, China has continued to increase investment, the white paper noted.

The country has improved the top-level design of green finance and set up nine pilot zones for reform and innovation of green finance in six provincial-level regions.

China has encouraged the development of green credit mechanisms, improved supporting policies for green bonds, and published a green bond project catalog to effectively channel private capital into addressing climate change, said the white paper.

As of the end of 2020, China's balance of green loans reached 11.95 trillion yuan, of which the clean energy loan balance stood at 3.2 trillion.

China has also issued about 1.2 trillion yuan of green bonds in total, making it the world's second-biggest green bond market. Enditem

维基解密创始人阿桑奇在庇护使馆监控曝光 穿短裤背心玩滑板消磨时间

阿桑奇在厨房过道锻炼身体的画面。

海外网4月19日电英国《每日邮报》日前曝光了一段阿桑奇在厄瓜多尔大使馆避难时健身的监控画面。只见视频中的阿桑奇不修边幅,不时挥动拳头,动作古怪,像是在和一个假想的对手“过招”。

监控画面中,47岁的阿桑奇握紧拳头,挥动着双臂,在厨房旁边狭小的过道间来回走动。

期间,他不时喝着果汁,然后在厨房和房间的走廊之间来回踱步。

视频画面中的另一幕是他站在电炉旁,一边准备做饭,一边跳动着,似乎在活动腿脚。画面中的阿桑奇一头白发,衣着随意,不修边幅,与早前的形象大相径庭。

《纽约邮报》此前也曝光过一段阿桑奇在厄瓜多尔驻伦敦大使馆避难时的录像,画面中的阿桑奇全身皮肤苍白、身着背心短裤,光着脚踩在滑板上向前移动,跌跌撞撞地在屋里玩滑板。

“维基解密”创始人阿桑奇自2012年6月起进入位于伦敦的厄瓜多尔驻英国使馆寻求庇护,近7年间一直未踏出使馆一步。《每日邮报》称,阿桑奇被指个人卫生情况糟糕,使馆工作人员对他抱怨连连,这也是他被撤销庇护的原因之一。厄瓜多尔内政部长玛丽亚·葆拉·罗莫(Maria Paula Romo)透露,阿桑奇在厄瓜多尔大使馆避难期间,经常作出一些粗鲁行为,他甚至“把粪便涂到墙上”。

4月11日,阿桑奇被英国警方逮捕。(每日邮报)

2019年4月11日,厄瓜多尔撤销了对阿桑奇的政治庇护,英国警方当天进入使馆逮捕了阿桑奇。英方证实,逮捕缘由包括美方发出引渡请求。阿桑奇的律师表示,阿桑奇将反抗到底。阿桑奇的父亲则呼吁称,希望澳大利亚政府能介入,将儿子引渡回国。(海外网 张敏)

US temporarily relocates embassy in Ukraine to western city of Lviv******

AFP

A woman passes by the closed US embassy in Kiev after operations were moved to Lviv on February 14, 2022.

US Secretary of State Antony Blinken announced on Monday that the United States will temporarily relocate its embassy in Ukraine from the capital city of Kiev to the western city of Lviv, citing escalating tensions on Ukraine's borders.

"We are in the process of temporarily relocating our Embassy operations in Ukraine from our Embassy in Kyiv to Lviv due to the dramatic acceleration in the buildup of Russian forces," Blinken said, using the Romanized spelling of the name of the capital city from the Ukrainian language.

"The Embassy will remain engaged with the Ukrainian government, coordinating diplomatic engagement in Ukraine," the secretary said, adding that his country also remains "engaged with the Russian government" and that the "path for diplomacy remains available."

The State Department on Saturday ordered the departure of most US direct hire employees from the embassy in Kiev, a decision it claimed was made "due to the continued threat of Russian military action" against neighboring Ukraine.

Passport, visa and other routine consular services have been suspended since Sunday, according to the department, and the mission of the now-reduced US diplomatic team is to "handle emergencies" in Lviv.

US and Russian top diplomats and defense officials held separate telephone conversations Saturday to discuss the Ukraine crisis, followed later in the same day by a high-stakes phone call between US President Joe Biden and Russian President Vladimir Putin.

In addition to evacuating its diplomatic staff, the United States has also been urging its nationals currently in Ukraine to depart immediately, warning that those who choose to stay cannot count on the US military to come to their rescue in the event that war breaks out in Ukraine.

Washington has been releasing intelligence purporting an imminent Russian invasion of Ukraine but refused to back it up with details. Moscow, for its part, has repeatedly denied any intention to invade, accusing the Biden administration of "hysteria."
