Real time navigation and fast positioning

Beidou satellite navigation system is composed of three parts: space segment, ground segment and user segment. It can provide high-precision and reliable positioning, navigation and time service for all kinds of users all day and all day around the world. It also has short message communication capability. It has preliminary regional navigation, positioning and time service capabilities, with positioning accuracy of decimeter and centimeter, The speed measurement accuracy is 0.2 M / s, and the time service accuracy is 10 ns

other features:

1. Precise time service

Beidou satellite itself is a time service system of our country. The precision of onboard rubidium atomic clock on beidou-3 satellite is at the international leading level, which can reach 5 parts per day of 10 billion. At present, this function has been used in communication, power, finance and other systems

2. Position report through the joint efforts of two geostationary satellites, it can not only answer the "where am I" of users, but also tell the relevant parties who pay attention to the whereabouts of users "where are you". It is widely used in search and rescue, fishery and other fields, and is a "thousand mile eye" to ensure the safety of people's livelihood

Short message communication navigation satellite and communication satellite are two types of satellites, but Beidou navigation satellite has additional communication function. This function is very important in desert, ocean, deep mountain, forest and other areas without network coverage, or when disaster occurs or communication is blocked

with the continuous development of 5g mobile communication, blockchain, Internet of things, artificial intelligence and other new technologies, as well as the further integration with Beidou system, we will build an emerging instry ecological chain with Beidou space-time information as the main content, promote the change of proction and life style and continuous innovation of business model, and create huge economic and social benefits

As academician sun Jiadong, the first chief designer of Beidou satellite navigation system, once said, "the application of Beidou is only limited by human imagination.". The future application value of Beidou is totally inestimable

7. With the strong growth of China's economy, the number of multinational enterprises and regional headquarters in China is increasing year by year, and the international competitiveness of Chinese enterprises is becoming increasingly prominent. And the optimization of internal control, management and operation of these enterprises has become the tip of the iceberg, and graally surfaced. As a result, it, HR, especially financial shared service center, which came into being, has quietly become popular... Motorola, Nokia, Ge, abb, McDonald's and many other enterprises in China have established shared service centers. It is predicted that by 2010, 90% of the companies in Europe, America and other developed countries and regions will establish shared service centers. Among all kinds of shared service centers, the most popular one in the world is Financial Shared Service Center, which is commonly referred to as financial document management outsourcing service. The so-called Financial Shared Service Center is to centralize various financial processes in a specific location and platform, usually including the processing of financial A / P, a / R, general ledger, fixed assets, etc. This mode will bring obvious results in improving efficiency, controlling cost, strengthening internal control, information sharing, improving customer satisfaction and resource management. When we talk about the concept of Financial Sharing Service Center, we have to mention Fuji Xerox, the leader of global financial document management service. Fuji Xerox has helped many international well-known enterprises, including Nokia, to set up shared service centers and realize the sharing and centralization of financial document management. It is the enterprise that has established and managed the most financial shared service centers in the world so far. It is understood that before the establishment of the Financial Sharing Service Center, Nokia's suppliers had to send all the documents to the financial departments of local branches for separate processing, which was not only cumbersome, but also difficult to save. Fuji Xerox's financial document management service transforms its document processing mode into electronic centralized management, freeing the staff from the monthly heavy document processing work, which not only saves manpower, but also greatly improves work efficiency. Statistics show that after adopting this service, Nokia's supplier document processing process has been reced from 48 steps to 12 steps, and the processing time of each document has been reced from 5 days to 2 days. With the application of Financial Sharing Service Center in Europe and the United States and other developed countries graally mature, as well as the rapid growth and development of the Chinese market, the demand of multinational companies and large domestic enterprises in China for this service is also increasing. Take a well-known international catering giant in China as an example. It has also established a financial sharing service center through the outsourcing services of Fuji Xerox. Using this digital financial management platform, the catering giant's accounting center began a new way of working. Among them, the financial personnel in charge of accounts payable only need to scan the bills into electronic files every day, add the key words, and upload them to the management platform. The system will generate the corresponding electronic vouchers and enter the financial approval process. All branches can query invoice information and payment process independently and quickly through the digital financial management platform. It not only greatly improves the work efficiency, but also simplifies the query process of departments and remote companies. Through resource integration, the Financial Sharing Service Center will allocate resources more effectively, avoiding the phenomenon of idle resources in the traditional decentralized processing mode. After the establishment of the Financial Sharing Service Center, the number of staff who used to focus on input decreased from 25 to 5, and the number of invoice filing staff decreased from 6 to 1. At the same time, enterprises can optimize the allocation of various resources including human resources. For example, in the accounting center, financial personnel can be flexibly deployed according to real-time workload changes to meet the needs of timely processing“ Because of Fuji Xerox's leading technology and rich experience in document management, it has provided many enterprises with overall solutions including financial process consulting, document management services, sharing platform establishment and ERP integration. " Chen Xuebo, business development manager of global service department of Fuji Xerox (China) Co., Ltd., said, "as the leader of document management outsourcing services, the number of customers of Fuji Xerox in China's Financial Sharing Service Center is growing exponentially, including many large state-owned enterprises." At present, a large domestic construction enterprise is also graally building its own financial sharing service center. At present, some bureau group units have been online, and the construction scale has been in the absolute lead in China. The effect of financial sharing services is graally emerging. Because the Financial Sharing Service Center solves the common problems faced by enterprises, improves the efficiency and optimizes the operation of enterprises, and makes enterprises focus on the expansion of core business, so it has developed rapidly in recent years. Since 2005, its annual global growth rate has exceeded 25%. At present, it has become a market with an annual turnover of more than 2 billion US dollars. It is estimated that this period of rapid development will continue for decades.
