What is the reason for inaccurate positioning

1. Environmental factors

The accuracy of mobile phone positioning is largely affected by the surrounding environment to a large extent.For example, if you are in areas where the network signal is weak or the surrounding environment is covered, such as the high -rise building or underground space, this may interfere with the mobile phone to receive the GPS signal or mobile network signal, which will affect the accuracy of the positioning.

2. Signal interference

In addition to environmental factors, mobile phone positioning may also be disturbed by other signals.For example, harsh weather conditions may cause electromagnetic wave transmission, which affects the accuracy of mobile phone positioning.In addition, using the mobile phone metal protective cover may also interfere with the mobile phone signal, which will affect the positioning.

3. Equipment quality

Equipment quality also affects the accuracy of real -time positioning of the positioning instrument.If you are using a device with relatively low cost, there may be some errors during the positioning process.If you need higher accuracy positioning results, it is recommended to buy better quality equipment.

4. Electricity

The power of the positioning instrument will also affect the accuracy of real -time positioning.If the equipment is insufficient, then it may not be able to receive signals or transmit data normally, resulting in inaccurate positioning in real time.Therefore, when the positioning instrument is used, it is necessary to ensure sufficient equipment.

5. Device settings

If your positioning instrument is not set up properly, the real -time positioning will also be inaccurate.For example, the time setting of the device is incorrect or the satellite signal types that are not used are not matched, which may cause errors in the positioning results.Therefore, when using the positioning instrument, you must read the equipment instructions carefully and set the correct settings in accordance with the instructions.

How to solve the inaccurate mobile phone positioning

1. Comprehensive use of multiple positioning methods

At the same time, the mobile phone's GPS, mobile network, WiFi, and Bluetooth function are enabled to achieve more accurate positioning through multiple ways to complement each other.

2. Check the application positioning permissions

If the mobile phone still cannot be positioned accurately, the application positioning authority may be closed.You can check and open the relevant permissions in the [Settings]-[Positioning Service].

3. Update system and application

The update of system and application often contains the optimization and improvement of the positioning function.It is recommended to check and update the application of the mobile phone system and the application of the positioning function to ensure the accuracy and stability of the positioning function.

4. Clear the cache and restart the equipment

You can try to remove the mobile phone cache or restart the device to restore the normal operation of the positioning function.

5. Calibration compass

The function of the mobile phone also has a certain impact on positioning.If the function of the compass is deviated, the positioning may be inaccurate.Therefore, it is recommended to calibrate the compass of the mobile phone regularly to ensure its accuracy.

How to find the position of the other party's mobile phone

1. Use mobile phone positioning service

Most mobile phones have built -in positioning services, which are usually based on GPS (global positioning system) or other positioning technologies.If the other party is willing to share their location information, they can open the positioning function in various applications (such as maps, social applications, etc.) and actively share the real -time position for you.This method requires the other party's active cooperation, and it is only applicable to the other party's mobile phone positioning service.

2. Inquiry through telecommunications operators (required legal authorization)

In some special circumstances, if you involve legal procedures or security investigations, you may need to obtain the location information of your mobile phone.At this time, it is usually necessary to apply to the telecommunications operator and present a legal authorization or certificate.After verifying your identity and request legality, the operator may provide a general location information of the phone.However, this method involves complex procedures and legal procedures and should not be used at will.

3. Specialized mobile phone positioning software (only emergency situation and legal authorization)

These softwares usually need to install and authorize related functions on the target mobile phone.After installation, the software can track the position of the mobile phone through the network positioning technology.However, this method also involves privacy and legal issues, and it is necessary to obtain the clear consent of the mobile phone owner to use it.

[mobile phone GPS positioning] Base station positioning and GPS positioning which are the best and disadvantages of the two mobile phone GPS positioning methods.

There are two types of positioning technology, one is a positioning based on GPS, and the other is the positioning of the base station based on the mobile operation network.The GPS -based positioning method uses the GPS positioning module on the mobile phone to send its own position signal to the positioning background to achieve mobile phone positioning.The base station positioning uses the calculation distance of the base station's distance to determine the location of the mobile phone.The latter does not require the mobile phone to have GPS positioning capabilities, but the accuracy depends to a large extent on the distribution and coverage of the base station, and sometimes the error will exceed one kilometer.The former has high positioning accuracy, but the GPS satellite signal penetration is weak, so it cannot be used indoors and consumes high power consumption.In addition, there is a way to use WIFI to locate in a small area.

1. GPS positioning:

Advantages: high positioning accuracy; free interface can be called at any time; global positioning.

Disadvantages: Applying mobile phone traffic and GPS functions in mobile phones, which consumes more power; the signal can penetrate poorly, and the thickness of the cloud layer has an impact on the signal; the indoor cannot be located.

Positioning method: The positioning request is initiated by the GPS terminal, and the initiative is in the terminal.The terminal does not want to ask for positioning that is to uninstall the system pre -installed or close the GPS to terminate.GPS is positioned as a request request, and the server cannot actively locate the position of a terminal.

Application environment: car navigation, aviation, shipping, website Business Services, etc.

Product Case: Kailid's vehicle navigation system

2. Base station positioning

Advantages: high positioning rate; no software; no traffic; no environmental environment can be located.

Disadvantages: The positioning accuracy is low, and the positioning of high -level office positioning is poor. The positioning depends on the mobile phone SIM card.

Positioning method: The terminal cannot actively locate. The terminal device only requires a SIM card. It does not need to make any settings. The server has positioning control power to accurately position the location information of a certain terminal device at any time.Since the positioning of the base station is lost to the ground positioning, the positioning accuracy depends on the signal tower, and the high -level office will affect the signal.The positioning of the base station has the characteristics of compulsory positioning. It needs to be opened by the operator's authorization and the positioning of its port docking and usage positioning. At present, it is only authorized by enterprises and institutions.

Application environment: supervision of corporate personnel, Outdoor emergency rescue, logistics

Product Case: Enterprise Effect Mobile Positioning System

There are certain restrictions on the use of positioning technology alone. The combination of mutual combination to supplement each other's deficiencies can achieve better results. GPS is relatively well known to the public.Positioning.Different from industry characteristics and application scenarios, the positioning of base stations plays a very important use in practical applications.

The communication operation high will provide corresponding location services. Each of the three major communications operators across the country has an independent location service package. It mainly solves local needs and requires that the mobile phone number must be unified.

3. The difference between GPS is positioned on mobile phone positioning

GPS positioning, GPS navigation, the application of these GPS has gradually made GPS technology well -known. Many smartphones have new tricks to attract everyone's attention, and mobile phone GPS came into being.The name of the mobile phone GPS is the function of realizing the GPS on the mobile phone. One is GPS navigation and the other is the GPS positioning tracking.GPS and mobile phone positioning are no stranger to many users who use smartphones.

Mobile GPS, which is a GPS positioning navigation function implemented on the mobile platform. With the development of technology, there must be more applications.This is easy to understand that in addition to the basic functions of text messages, calling, taking pictures, MP3 and other basic functions such as mobile phone communication, you can also use your mobile phone to achieve GPS positioning navigation.GPS mobile phones are also mobile phones with navigation functions, so GPS mobile phones can also be called GPS navigation phones or mobile phones with GPS navigation functions.

What is mobile phone positioning

mobile phone positioning refers to the location information (latitude and longitude coordinates) of mobile phones or end users through specific positioning technology, and marked the technology or service of the position of the positioning object on the electronic map.There are two types of positioning technology, one is based onGPS The positioning of the positioning is based on the base station of the mobile operation network.based on GPS The positioning method is to use the mobile phone GPS The positioning module sends its own location signal to the positioning background to achieve mobile phone positioning.The base station positioning uses the calculation distance of the base station's distance to determine the location of the mobile phone.The latter does not need a mobile phone to have GPS Positioning ability, but the accuracy depends to a large extent on the distribution and coverage of the base station, and the error will exceed one kilometer.The former has a higher positioning accuracy.Also use wifi Positioning in a small range.

The principle of mobile phone positioning

mobile phone positioning refers to through the wireless terminal(( cell phone Cure Coordinate with the wireless network to determine the actual location information of the mobile user (( Lepatinity coordinate data, including 3D data Cure ,pass SMS As well as MMS Voice is sent to users or provides some value -added services based on this.Positioning service is also called mobile location service (Location Based Service ,, LBS) , It is the network of telecommunications mobile operators (( like GSM net, CDMA net Cure Get the location information of mobile terminal users (( Latitude coordinates Cure With the support of the electronic map platform, it provides users with a value -added business for corresponding services.

mobile phone positioning is usedGSM The honeycomb technology of the mobile communication network to realize the location information query, GSM The wireless communication network is built from many communities like bee honeycomb. Each community has its own number. You can know the area where the mobile phone is located through the identification number of the mobile phone.At present, the positioning technology of mobile phone communities is still perfect, and the accuracy range in the urban area is roughly 200 About rice, the accuracy range of the suburbs is roughly 1000 rice ~ 2000 With around the rice, with the continuous development of the technology of mobile companies, I believe the accuracy will be further improved to further 50 Within rice.At the same time, the landmark name displayed at the same time is still optimized. As further optimization, the landmark will be more accurate.

Honeycomb positioning technology also belongs to the LBS base position positioning. This positioning method is commonly known as the ground positioning system because it relies on the signal tower distributed by the operator to obtain the latitude and longitude information to determine the position of the terminal.As long as all mobile phone cards are in the activation state, and can normally receive calls, they can be accurately located. Strong positioning capabilities, positioning signals can effectively penetrate the building, basement, and tunnel traffic.Each mobile phone card has the only identification code, just like a phone call, each number is the only point to the fixed mobile phone, the LBS base station positioning can also effectively find a fixed number through this recognition code to find a fixed number numberThe location of the mobile phone is presented to the electronic map. Such positioning technologies are compulsory and are widely used in some regulatory fields.

Features of mobile phone positioning

1 High coverage

On the one hand, the range of coverage is large enough.On the other hand, the scope of coverage includes indoor.Most of the time users use this function in the room, from high -rise buildings and underground facilities must be covered to each corner.According to the scope of the coverage rate, mobile phone positioning can be divided into three types of coverage services: the entire local network, covering some local networks, and providing roaming network services types.In addition to considering the coverage rate, the environmental factors of the network structure and dynamic changes may also make a telecommunications operator unable to guarantee services in local or roaming networks.

2 , Positioning accuracy

mobile phone positioning should provide different accuracy services according to the different user service needs, and can provide users with the right to select accuracy.For example, the United StatesFCC The positioning accuracy launched is 50 The probability within the rice is 67% , Positioning accuracy 150 The probability within the rice is 90% EssenceOn the one hand, the positioning accuracy is related to the positioning technology adopted, and it depends on the external environment of the business, including the radio communication environment, the density and geographical location of the base station, and the equipment used in positioning.

The role of mobile phone positioning

1. Parents position the elderly and children

It is mainly due to the needs of security and care. It is installed on the mobile phone of the elderly and children. Once lost, send a text message to get the specific map location of the elderly and children.

2 , Enterprise Management of Vehicle

GPS The signal is transmitted through satellite, restricted by the cloud layer and obscuration, there will be no signal in cloudy, basement, and tunnels to generate blind spots.Based on sim The positioning technology of the card is what we call the ground positioning -the enterprise effective LBS The positioning of the base station can effectively feedback the location information on the location on the ground. LBS The base station positioning saves the terminal cost, and the existing mobile terminal can be used directly, which saves the entire project cost. LBS Suitable for regulatory positioning requirements, and continuous positioning communication tariffs are relatively high.

3 The management of employees by enterprises

It can provide management for sales companies with multiple branches and work hours of sales staff. ; Mainly use base station positioning, which can be positioned with foreign duty employees to achieve mobile attendance, itinerary management, trajectory inquiry, visit management, etc., improve employee work efficiency, and reduce travel costs.

4 , Make remote decoding

The internal program where the opponent's number is located or fixed -line is bound to his number. After the binding, you can perform unlimited distance monitoring, interception, and positioning function.

What are the ways of mobile phone positioning

1. GPS position

Actually, I do nt need to say, everyone must know, first of allGPS Positioning, in general, the current mobile phone chip is supported GPS The positioning, that is, you don't want to support it, you can't be positioned.

2. WIFI position

Thenwifi Positioning, each wifi There is a unique one mac Address, when the mobile phone is turned on wifi At that time, it starts scanning and collecting surrounding routers wifi Signals, upload their location information to the server to form a huge hot spot position database.

This iswifi position.Although you can close it in theory, some you can't close it, because some software is like checking the household registration, you must support positioning to use.

3 , Base station positioning

There is also a positioning method, that is, the base station positioning, that is, the base station can locate your mobile phone through your mobile phone card.As long as your phone has a signal, others can track your position by checking which base station has contacted your phone.

In simple terms, at present, the approximate way of positioning is these.

Use your mobile phone number to locate how to find someone

1. Positioning based on GPS

Use the GPS positioning module on the mobile phone to send your position signal to the positioning background to achieve the positioning of the mobile phone. The positioning accuracy is high, and the method of positioning the WIFI in a small range.

2. Positioning of the base station based on the mobile operation network

The base station positioning uses the calculation distance of the base station's distance to determine the location of the mobile phone. This method does not require the mobile phone to have the GPS positioning ability, but it depends on the distribution and coverage of the base station. Sometimes the error will exceed 200 meters. ThereforeIn terms of accuracy, it is not as good as GPS positioning.

When you need a friend or family you need to care about the accident, where can you pass? The mobile phone number quickly determines that the opponent's general position can be found.You can also manage the employee's foreign service route and pay attention to the employee's foreign service attendance through the mobile phone number. For the logistics team, you can also investigate the general location of the vehicle cargo through the mobile phone number.

one,cell phoneHow much is a pocket

1. Fabric mobile phone package: This is the most common variety of mobile phone packages. Not only the materials are durable, but also very affordable. Generally speaking, the price of ordinary fabric mobile phone packages only costs about ten dollars, but if it is a well -known brand mobile phoneIf you bag, the price may be more expensive.

2. PU mobile phone package: This is also a commonly used fabric for mobile phone packages.wait.

3. Leather mobile phone waist bag: The noble and elegant leather bag can always show the unique taste of the user, and the leather bag is also very durable. The classic will never be outdated. The price of the leather bag depends on the size of the bag.It's smaller, so the price is near 200 yuan.

2. How to choose a suitable mobile bag

1. Style

I think the style of the bag is simpler and better, but it must have exquisite details and good workmanship. A rough bag will not have beauty anyway.I prefer soft Bags, I don't like hard Bags.And many people think that wearing a lot of clothes in winter should be carried on a large bag. In summer, I feel that it is just the opposite. In winter, I should wear a small bag in winter to balance the vision to avoid looking bloated;And when you wear little in summer, you must carry a large bag, so as not to seem light fluttering, but also to balance.Another important thing is that try not to carry the shoulder bag in the summer, especially the plump MM. There is no need to repeat it in this reason ~ huh.

2. Of course, the color is to look at the colorful color

The more pure, the better, and the matching, you need to come according to the clothes. Do not carry a bag that is the same or close to the color of the clothes. I would rather wear a red bag with a green bag.Stupid, I think.But except for black and white.

3. Of course, the texture is best

However, considering the cost, as long as the texture is good, the rotten and sparse texture will definitely not make any good Bags.However, it is best to choose sheepskin with beautiful and deep colors. It is better to choose cowhide with light colors.In short, there can be no Chinese service, and a sincere bag must be missing!Otherwise, the Chinese clothes will become a pale paper.

4. Clothing and Bags: coordination of fabrics and colors

If you are a girl who is chasing fashion and loves to wear popular color clothes, then you should choose fashion Bags that are coordinated with popular colors; if you love to wear solid clothes, you should equip yourself with some bright and fancy Bags.If you love wearing a young clothing such as T -shirts and sweatshirts, you should choose hard Bags such as nylon, plastic, thick canvas; if you love wearing woven sweater, shirts and other girls, you should be equipped with some lace and hempOr soft cotton and other soft Bags.Of course, the clothing fabric is changed, and the texture of the bag also needs to be replaced accordingly.

5. Face shape and bag: rigidity and softness

If you have a little boyfriend, such as clear facial features, high eyebrow peaks, and prominent cheekbones, it is best to choose a masculine fashion bag with stripes; and girls with gentle eyes, round nose, melon seed face and other girls are full of taste.Girl, it's best to choose cute with beads and sequinsBagEssence
