Li: Status and prospect of position cloud

"China Global Positioning System Technology Application Association 2011 Annual Meeting and Beidou industrialization and strategic emerging Industry Development Forum" in Beijing on November 8, 2010. At the meeting, Professor Li of Peking University made a report entitled "Status and prospects of position clouds", the following is a transcript.

Jianguo：

Ran director gave us a good report, comprehensively introduced the construction of the second generation of the Beidou and the current progress, on the next step of industrialization to talk about their overall thinking. This paper puts forward the main tasks, challenges and measures taken in the whole idea, and gives a detailed introduction to the current progress of industrialization. He mentioned the goal of the 2015 chip breakthrough, the application of innovation breakthroughs, and the formation of large-scale situation. The task is still very difficult. Ran general report to our relevant departments, especially many enterprises, in the planning next year and the next five years, our Beidou construction synchronization can adapt to this development situation? How and GPS compatible, our research and development work, product planning will have a positive significance. Thanks for the report of director ran.

Below please the Peking University professor Li to do "the position cloud present situation and the foreground" the report, everybody welcome.

Li：

Good morning, everyone! I mainly talk about the position cloud, one is its background, and the other is the position cloud how to serve the public.

First, let's talk about cloud computing and virtual worlds. Cloud computing is now overwhelming, and cloud computing has not only brought about a revolution in information technology, but more importantly a change in the information world. When using cloud computing for physical refactoring, we can constantly fix our knowledge of the physical world and make it closer to reality. What is cloud computing? Now about the cloud concept emerging, basically belong to elephant level, always simple, in my opinion, I think cloud computing is for the purpose of application. Through the Internet, a large number of necessary software and hardware are connected according to certain organizational forms, and a virtual resource service set with minimal internal friction and maximum efficiency is created by dynamic adjustment.

When we call these services, the standard is packaged as a service. The first is the resource, cloud computing is actually on demand to create a minimal internal friction, the most effective virtual resource services collection. The collection of virtual resource Services provides an environment for on-demand computing and on-demand services. Cloud computing providers can be sold, and cloud users can use them on demand.

We have a definition of the cloud. What is the concept and relationship of cloud computing and virtual world? The virtual world refers to a world that is created by objects with the ability of conscious activity, which are not bound by the natural laws of the world in which they reside.

The virtual world created by cloud computing is a computer-borne, and its hardware and software are connected by a certain form of the technology effect. The virtual world created by the brain is a neuron-carrier and an important part of human existence. This definition can objectively look at what we are facing is actually the stage when people, machines and brain need to work together. This is what we mentioned the so-called new generation of digital Earth, is to pursue, human, machine, brain space three synergy. This is becoming reality, one is our real world, the other is our virtual world. Our virtual world through the computer network, through a variety of satellite applications has become a reality we can touch. And this is what we can feel through the mobile phone, so the truly complete embodiment of our current stage, can already touch the environment, should be a cloud computing environment.

(PPT) The ball is expressed in real-time flight status worldwide. The picture on the left is the first cell phone, and we have a variety of satellite information that can be sensed by mobile phones. In cloud computing and cloud services, it brings us profound changes today, and we have been able to shield the complexity of networks, data, and so on through cloud computing environments. Users only need to make a request, this is called on-demand services. This is the environment we expect, and the environment is now coming to us. One is the real world, one is the virtual space, the virtual space is not only the bit world, but also includes the culture. Our stream of consciousness can also be expressed by digitizing it, through virtual reality. This is what everyone has been able to realize today, what we need is a cloud and a computing environment that provides the services we need. With this technology and service environment, we can get a wide range of social applications of spatial information and technology. Just now I'm talking about clouds, the benefits of location-based intelligence computing to public information services. So for the digital Earth, it can also make us feel that it has an essential qualitative change and qualitative leap. This is the opportunity and challenge that we are facing now.

First, we can quantify understanding of the earth as a system. On this basis, we developed the first generation of digital Earth, in the first generation of digital Earth has been widely used on the basis, is now exploring the second generation is the next generation of digital Earth, intelligent earth.
