It is easy to calculate the GPS error with/without clock error.
GPS 3 sigma position error on earth surface with military signal : 6.048m
With 0 clock error : 5.708m

Same , in space with clock error : 3.21 m
Space, without clock error : 2.517m

So, elimination of clock error gives 0.3-0.7 m reduction of error, LESS than the error reduction achieved in the case of GLONASS by the introduction of Indonesian / south american ground stations.

So, anyone who think that the complete elimination of clock error can achieve decimetre precision lack the understanding in the next areas:
-basic geometry
-basic probability ( or skills in statistical process analysis , on turning machine operator level )

China's Chang'e-4 probe touched down on the far side of the moon Thursday, becoming the first spacecraft soft-landing on the moon's uncharted side that is never visible from Earth.

The probe comprised of a lander and a rover, touched down at the preselected landing area at 177.6 degrees east longitude and 45.5 degrees south latitude on the far side of the moon at 10:26 a.m. (Beijing Time), the China National Space Administration (CNSA) announced.

With the communication assistance of the relay satellite Queqiao, meaning Magpie Bridge, the probe sent back the first-ever close-up photograph of the moon's far side, opening a new chapter in lunar exploration.

After the Beijing Aerospace Control Center sent an order at 10:15 a.m., the Chang'e-4 probe, launched on Dec. 8, 2018, began to descend from 15 km above the moon with a variable thrust engine being ignited, said CNSA.

The Chang'e-4's relative velocity to the moon was lowered from 1.7 km per second to close to zero, and the probe's attitude was adjusted at about 6 to 8 km above the lunar surface.

At 100 meters up, the probe hovered to identify obstacles and measured the slopes on the surface. After avoiding the obstacles, it selected a relatively flat area and descended vertically and slowly.

Then the probe landed in the Von Karman Crater in the South Pole-Aitken Basin.

During the descending process, a camera on the probe took photos of the landing area.

I've just realised that A.C. Clarke foretasted in his books that China will be on par with USA regards of space technology by 2011.

Huawei launches next-generation chipset for servers as it aims to become a top 5 cloud player


Huawei unveiled on Monday a next-generation chipset for servers, potentially pitting it against the likes of AMD, even as the Chinese technology giant faces political headwinds around the world.

The new chipset, called Kunpeng 920, is designed to go into data centers and will power the company’s TaiShan server, which was also launched on Monday.

Huawei is keen to show it is pushing ahead with business despite major political headwinds, including the arrest of its CFO in Canada and continued accusations from the U.S. and others that the company’s equipment could be used as a backdoor by the Chinese government to spy on citizens.

In response to a question from CNBC about whether political pressure could affect sales of the new server, William Xu, Huawei’s chief strategy marketing officer and director of the board, told CNBC that the company hopes to attract customers by making good products.

“Only by achieving good-quality products can we win our customers. We will obey laws and restrictions in local markets, and eventually make products that are recognized and welcomed by customers,” Xu told CNBC in a Monday interview.

Huawei’s new silicon, known as a central processing unit (CPU), was designed by the company and based on a chipset architecture created by ARM, the U.K.-headquartered company now owned by SoftBank.


The Kunpeng 920 is a 7 nanometer chip, a designation tied to its size. Such technology is the latest in the semiconductor industry and allows for smaller components that are more powerful and energy efficient than their predecessors.

Huawei said its new servers with the Kunpeng 920 are designed to help process and store large amounts of data.

ARM has typically been a player in mobile devices with its chipsets, but it has of late tried to push into the server and cloud market. Huawei is not the only company with a 7 nanometer chipset designed for servers. AMD has its own product that it launched last year. Huawei’s latest move puts it in competition with the likes of that semiconductor firm and NVIDIA.

It’s also not Huawei’s first 7nm chipset. The company has the Kirin 980, which is designed for its own mobile phones, and the Ascend 910, which was created to handle artificial intelligence applications run in the cloud. The Ascend 910 is also designed for data centers, but serves a different function than the new Kunpeng 920.

Aiming for the top of the cloud
Huawei makes most of its money from selling telecommunications equipment. But it is searching for new avenues of growth such as consumer electronics and cloud computing. Huawei is hoping the TaiShan servers will help boost the latter business.

The technology giant has worked with Intel for many years on semiconductors for its servers, but the Kungpeng 920 is based off of ARM architecture. Xu said that Huawei will continue its relationship with Intel but it chooses the best option for each use case.

“Huawei and Intel are long-term strategic partners, in the past, now and will be in the future. The relationship between Huawei and Intel, though we have differences in our CPU structures, our products complement each other. We will keep using Intel CPU in areas where they perform better, and use ARM-based CPU in areas like cloud and servers where they are better,” Xu told CNBC.

There has been a broad move by Chinese technology companies to wean themselves off of American technology, particularly semiconductors. Huawei has pushed its own chips extensively in smartphones and servers and hopes the latest addition to its portfolio will eventually make it one of the top cloud players on the planet.

“We hope to make our cloud service, together with our partners, one of the top five cloud services in the world,” Xu said.

The current top cloud players are Amazon, Microsoft, IBM, Google and Alibaba, according to market insight firm Synergy Research.

Alipay deploys blockchain tech for remittances from Malaysia to Pakistan
Please, Log in or Register to view URLs content!

Ant Financial’s Alipay is deploying blockchain technology to power a cross-border remittance service for Pakistan’s Telenor Microfinance Bank (TMB) and Valyou of Malaysia.

The deal is designed to provide a faster, low cost method for Pakistani expatriates working in Malaysia, who send approximately US$ 1 billion annually back to their home country.

The Alipay offering claims to be Pakistan’s first blockchain-based cross-border remittance service. It is being provided to the Telenor Group, which owns and operates Telenor Microfinance Bank in Pakistan and Valyou of Malaysia. The blockchain service will make 24/7, real-time money transfers between the two countries at a competitive exchange rate with Alipay waiving transaction fees during the one-year trial period.

“The new remittance service is one of the examples of how emerging technologies can help countries meet their digital and financial inclusion goals. We’re thrilled to be part of Pakistan’s financial inclusion efforts and we’re dedicated to exploring breakthroughs and applying them to benefit more people in more places,” stated Eric Jing, chairman and CEO of Ant Financial, in the press release.

Telenor launched a mobile branchless banking service in Pakistan called Easypaisa in 2009 that now serves 20 million Pakistanis. The Easypaisa service will be used to receive the cross-border remittances and will enable Pakistani consumers to pay bills and shop both online and at the 70,000+ store that accept it. Last year,

acquired Prabhu Money Transfer, a Malaysian-based licensed money services business that provides international remittance services and rebranded it Valyou.

“Currently, Pakistan receives about US$ 1 billion in home remittances from Malaysia and this Easypaisa-Valyou collaboration is going to change it for the better,” stated Roar Bjærum, senior vice president, Telenor Financial Services, Telenor Group in the press release.

The spotlight on remittances has been very strong in the last decade as the

and the G20 nations have highlighted both the high economic impact of remittances on developing nations and how the high costs to send and receive money cross-border unfairly burdens unbanked and underbanked consumers.

Pakistan received almost $21 billion in remittances from countries across the globe, making it a major source of revenue.

“Home remittances contributed to over 6 percent in GDP, equivalent to over 50 percent of our trade deficit, 85 percent of exports and over one-third of imports during FY 2017-18,” noted Tariq Bajwa, governor of the State Bank of Pakistan in the press release.
