How to use the GPS satellite positioning system of Jinan Changyun Company
The realization of GPS function needs the support of both software and hardware. First of all, to receive GPS positioning information, the mobile phone needs a GPS positioning component, and the mobile phone also needs a map of the whole country or even the whole world, so that positioning is meaningful. For GPS mobile phones, please refer to the following article. GPS global positioning system is a wireless navigation system based on satellite positioning. Its positioning is achieved by using a constellation consisting of 24 satellites. At first, it was only used in the military. With the gradual development of science and technology, GPS is also widely used in business and people's lives. Its main feature is that GPS can achieve omnipotence (ocean, land, aviation, aerospace), global, all-weather, continuous and real-time through satellite navigation and positioning. Mio A700 is the world's first smartphone with built-in GPS satellite navigation module. No one tried it before A700. It can be said that the emergence of A700 indicates that Dentsu has written an important stroke in the field of GPS mobile phones. At the same time, the A700 mobile phone is also the first GPS smart phone in the world equipped with complete maps of Chinese mainland and Hongkong, as well as maps of more than 200 cities in the Mainland, which integrates the information of banks, restaurants, restaurants and shopping malls, with more than 6,543,800 pieces of life information. As a GPS navigation function, the most important thing is map resources. There are not many companies with map authorization in the world. Yuda Dentsu is one of the few companies with map authorization in the world, which greatly ensures the convenience and rapidity of map updating. These functions mentioned above are all realized by the GPS navigation system in the Mio A700 mobile phone. With the maturity of mobile phone industry in China, GPRS wireless network is not a new word. As a new product, GPRS originated from mobile phones and other devices with wireless networks. In recent years, it has been officially commercialized, and the number of users has increased year by year. In addition, mobile phone operators put GPRS in the ranks of automatic opening, which makes the popularity of GPRS reach an unprecedented height. It can be said that GPRS has become one of the most basic configuration functions of mobile phones. However, many mobile phone users don't know this emerging mobile phone business thoroughly enough. What is GPRS? What's the difference with GPS? What benefits can GPRS bring to users? Mio A700 mobile phone has both GPS navigation function and GPRS function, so what kind of special services can be brought to consumers after the combination of GPRS wireless network and Mio A700 mobile phone? Specifically, GPRS is a high-speed data processing service, which transmits data to users' mobile phones in the form of data packets. Therefore, surfing the Internet through GPRS mobile phone saves time, effort and money. On the other hand, GPRS is like ADSL of mobile communication equipment, while GSM network is just a common fixed telephone line. GPRS is different from GPS, which can obtain the network resources needed by users only through the network base station of mobile operators, while GPS can realize the navigation of road conditions only through satellites. They are two completely different ways of wireless service. With an appropriate metaphor, GPS is like a living dynamic map, which can guide the way, while GPRS is more like an internet network in the palm of your hand. There are also a lot of information resources in this network, which users can download on demand. /digital/mobile phone/10 1327/
