What is GPS? What is GPS?
First, tell the novices first! Mobile GPS is actually a hardware in some mobile phones! Not software! GPS hardware is the stuff that can achieve global positioning.
It does not charge any fees to use the GPS service. You can see it as a radio, but the satellite signal with a device with a GPS chip is free (24 satellites emitted for 24 satellites in the United States. , Give us free to use, maybe you think this is incredible, but this is indeed). but these received signals can tell you at most that your current latitude and longitude, so you still do n’t know the place name of your place, you need to convert the latitude and longitude of the latitude and longitude into a flat map, you need a set of software to translate it ( Or explain it). Then, this software that explains the latitude and longitude is the map program. In from the concept of just now, the GPS positioning navigation system is composed of two parts: software and hardware, and the software is the translation. You need to install a set of map navigation software in the GPS device to convert the latitude and longitude information into the position on the map, so as to display the geographical location of your place on the map, and navigation is also a function (navigation navigation (navigation of navigation (navigation (navigation (navigation (navigation (navigation (navigation (navigation (navigation That is, you set a starting point and end point, the map will calculate the route yourself and bring you to your destination). Cost mobile navigation software, in addition to Nokia's map program, also has many map programs such as Kaili, R6 6, Ren Mi, etc. can be installed. The map is generally used for free! However, of course, it is necessary to spend money on these maps. The cost is about hundreds of yuan a year. Intersection Ha ha! The further planning and construction of many cities at present, which means that navigation software also needs to be continuously upgraded and improved. Money upgraded map data files, such as Nokia Maps, can download the map loader on the official website to load the latest map data files by themselves.)
The concept of GPS, but there is still one The problem is troublesome. This problem is the A-GPA in the mobile phone. So what is A-GPA? a-GPS can be understood in this way, that is, a auxiliary function is added on the basis of the traditional GPS function. This auxiliary function is used to make up for the shortcomings of the traditional GPS positioning for the first time. Before the satellite signal, download a satellite information online, and then tell the GPS to GPS, and GPS can directly find the satellite.
The following are some questions about everyone who often ask AGPS. Summary, I hope everyone can have a comprehensive understanding of AGPS. In fact, these problems are not limited to Nokia mobile phones, and other mobile phones with AGPS functions are as applicable.
1, which mobile phones of Nokia with A-GPS function? : As of now, all mobile phones with GPS function launched by Nokia support AGPS function.
2, why does my N95 have no A-GPS function? : The original version of the n95's ordinary version does not have the AGPS function, but after upgrading the ROM to V12.0.0.013 or above, the N95 will be able to support the AGPS function.
3, what are the differences and advantages of A-GPS and ordinary GPS? : Traditional GPS positioning (cold start) usually takes a few minutes, and is generally affected by the positioning environment. For example, high -rise buildings will seriously hinder the acceptance of satellite signals. The GPS signal is also difficult to receive. The fastest time for the first positioning of AGPS takes a few seconds, which is also the biggest advantage of traditional GPS.
4, what are the disadvantages of A-GPS compared to ordinary GPS? : Ordinary GPS can only rely on receiving satellite signals, which is completely free. In addition to receiving satellite signals, AGPS also needs to download the star calendar information through the GPRS network of the mobile phone, and GPRS will spend extra money on the Internet.
5, how to understand the relationship between A-GPS and ordinary I-GPS? : A-GPS can be understood in this way, that is, a auxiliary function is added on the basis of the traditional GPS function. This auxiliary function is used to make up for the shortcomings of the traditional GPS positioning for the first time. Before you find the satellite signal, download a satellite information online, and then tell the GPS to the GPS, and GPS can directly find the satellite. 6, do mobile phones with A-GPS function have ordinary GPS functions? : As long as the AGPS feature mobile phones have both ordinary GPS functions, because the AGPS function is only an auxiliary of ordinary GPS. Without the GPS function, there is no way to talk about it. 7, do you have a mobile phone that only has A-GPS, and there is no GPS function? : For the reason, please refer to the answer above. In fact, there are many opinions in many evaluation articles that mislead the public. They believe that some AGPS mobile phones are located through the base station and do not have the GPS function. This statement is wrong. If a mobile phone does have an AGPS function, then it must also have (or connect to external) GPS function. (If you are not connected to the outside, his A-GPS function is at most a furnishings.) Otherwise, if a mobile phone can only rely on the base station to locate, it cannot be said to have the AGPS function. 8, A-GPS mobile phone must connect to GPRS for each use of navigation functions? Answer: Yes, because you need to rely on GPRS to download the Star Calendar information, it is necessary to connect GPRS.
9, can I turn off the A-GPS function separately? : It is possible on Nokia mobile phones, so that only the ordinary GPS function is used, and no GPRS traffic is needed. As for whether the mobile phones of other brands can be closed, I have not used it in person, so I dare not say it, but I guess, let's try it yourself. 10, what effect does it affect the navigation after turning off the A-GPS function? : No effect on navigation. Just start in GPS cold (GPS boot positioning is divided into three types: cold start, warm start and hot start: This start: The following situations are booting. When the battery is used for the first time; When the loss is lost; the distance between the receiver will be moved by more than 1,000 kilometers when the shutdown state. This start: the starting time of the last positioning of more than two hours. Start at an hour. Sometimes if the machine has software problems, you need to start with cold, and you can use GPSViewer for cold start.) It will be slower, which takes about a few minutes, but it is normal to wait for the satellite. 11, how do Nokia mobile phones turn off the A-GPS function? : Enter function tables> Settings> Mobile phone settings> Conventional> Positioning> Positioning method to cancel the "Network Auxiliary GPS" option and retain only the "Integrated GPS" option. Since different types of mobile phone menu may not be exactly the same, please refer to the steps above. 12, how to fill in the access point and access server of Nokia mobile phones? : Enter the function table> Settings> Mobile phone settings> Conventional> Positioning> Positioning server access point (selected according to your network itself), access the server fill in Supl.nokia. Since different types of mobile phone menu may not be exactly the same, please refer to the steps above. 13, how is the cost of using A-GPS? : When using AGPS, the GPRS traffic fee will occur because you need to connect the GPRS network to download the Starry Calendar. Downloading Star Calendar is free. Therefore, there will only be GPRS flow fees at present, and the amount of data is not large. (In the case of open -air, as long as you are not hiding in areas that cannot receive satellite signals, such as closed rooms, tunnels, and basement in the basement) 10KB. 14, except for the cost mentioned above, does it cost? : As for other expenses that will occur, it has nothing to do with the use of AGPS, but also talk about it, let everyone know. Nokia GPS mobile phones are currently pre -pre -pre -pre -pre -pre -pre -pre -pre -pre -pre -pre -pre -pre -made maps (don't be confused, navigation software and maps are not the same thing. If you are not set, you need to download your location in real time after GPRS real time after opening the map. Map data file. Of course, you can download it on the computer in advance and copy it into the phone. This can save a lot of GPRS traffic fees. Please see the link below in detail). There is another nokia Maps voice navigation (some Nokia mobile phone navigation version will built in a free trial period for a period of time, such as half a year). You can only try for 3 days for free. It takes dozens of euros a year, and can also be purchased at the Nokia online mall. The current cost of one year is 728 yuan. Therefore, it is recommended to download and install the Nokia Map XX version or R oute 66. R oute 66 is currently the most popular navigation software on the Saipan system. After installation, other costs will not be incurred. 15. I want to use GPS positioning and navigation. What should I do? : Function table -tool (or program) -With a GPS data (or GPS Data), open it (do not close), then open the map in the menu, wait for the positioning, then return to the back, then return to the back, then return to the back, then return to the back, then return to the back, then return to the back. GPS Data, choose navigation, and then set the place you want, (or choose the place you want to get on the map, press the middle key, and then choose according to your own needs)
In fact, there is no difference. The main difference is to see the quality of the mobile phone map software
Well, I think Tencent's map is good. Through the street view of Tencent Maps, users can realize online virtual tourism or go to a certain way to a certain way. Knowing the surrounding environment before the ground, it is easier to find the destination. At the same time, street view maps can also provide reference information for renting houses. It can query bus stops and bus routes, driving routes, locations, location positioning, viewing surrounding group purchase information, real -time road conditions, weather, and ranging. Tencent Map is an Internet map service provided by Tencent, covering nearly 400 cities across the country. Users can see ordinary rectangular maps, satellite maps, and street view maps from the map. They can also use maps to query the geographical location of banks, hospitals, hotels, parks, etc. to meet the needs of users' daily life. In short, Tencent Maps is the best map I can find on the market. And it's completely free, dear
This is almost the same. The original poster does not have to entangle It use a good navigation
Igly, the landlord uses Tencent map, it is completely free, download the offline map navigation traffic Tencent map covers nearly 400 cities across the country. Users can see ordinary rectangular maps, satellite maps, and street view maps from the map. They can also use maps to query the geographical location of banks, hospitals, hotels, parks, etc. to meet the needs of users' daily life.
