What Is a Smartphone with GPS?

A GPS mobile phone refers to a mobile phone that integrates GPS positioning technology in a mobile phone to obtain the mobile phone's position information (latitude and longitude coordinates), and combines geographic information management system (GIS) to achieve positioning and navigation functions and other special-purpose mobile phones.

GPS Phone

The only main function of GPS is positioning, and the combination of GPS positioning technology and other technologies will generate many functions. The most common is the navigation function. A GPS mobile phone is also a mobile phone with a navigation function, so a GPS mobile phone can also be called a GPS navigation mobile phone or a mobile phone with a GPS navigation function. In fact, with the development of technology and the opening of the 3G network, GPS mobile phones will have more applications, such as: GPS navigation mobile phones, field staff management mobile phones, GPS elderly mobile phones, GPS

GPS mobile phone is composed of GPS module and GSM communication module.

The GPS module completes the data collection of GPS satellites such as search and tracking and positioning speed.

The GSM communication module completes the communication function of the mobile phone, and can process the collected GPS data and upload the designated website according to the mobile phone function.

(1) The ground control part consists of the main control station (responsible for managing and coordinating the work of the entire ground control system), the ground antenna (under the control of the main control station, injecting a message to the satellite), and the monitoring station (the automatic data collection center) And communication

(1) All-weather; (2) Global coverage; (3) High-precision three-dimensional fixed-speed timing; (4) Fast time-saving and high-efficiency: (5) Wide application and multi-function.

However, if the field of vision is not wide, such as under a tree or in a room or an underground parking lot, a sufficient number of positioning satellites cannot be found, and positioning cannot be performed.

The GPS mobile phone business has a huge industry chain line-up that exceeds traditional value-added services. It consists of mobile operators, system equipment providers, terminal manufacturers, GIS developers, application providers, middleware providers and other links.

10. Risk monitoring and management of outdoor workers: patrol police, traffic police, plain clothes, public security duties, taxi drivers, fishermen, herders.

11. Community Correction Staff Monitoring

According to relevant laws and regulations, correction personnel must not leave the county or city area without authorization.

A GPS mobile phone is a mobile phone that has both general communication and navigation functions. There are many mobile phones with navigation functions. The key to buying a navigation mobile phone is to look at the following points:

1. Is the screen large enough, because the screen is too small to see clearly, it is very inconvenient to use;

2. Whether there is an electronic dog function. The so-called electronic dog function is the reminder function of the monitoring system. It can remind you how many meters ahead there is a speed monitor and the speed limit. It can also remind you that there is a camera in front. Please Do nt run out of red lights, reminders, etc. are very useful.

3. The map must be able to be updated, because roads change every year, such as new roads, adjustment of single and double lanes, etc., so the map of the navigation in the mobile phone must also change, otherwise it is very inconvenient.

4. Determine whether it is a GPS mobile phone or an A-GPS mobile phone. The accuracy of the GPS mobile phone is high, and the accuracy of the A-GPS mobile phone is slightly lower;

5. Confirm whether there are other costs incurred during the use of mobile phone navigation, such as network traffic charges or GPS software usage charges.

Because of GPS's all-weather, high-precision, and automatic measurement characteristics, as an advanced measurement method and new productivity, it has been integrated into various application areas of national economic construction, national defense construction, and social development.

With the end of the Cold War and the booming global economy, the U.S. government announced that from 2000 to 2006, under the premise of ensuring that the national security of the United States was not threatened, the SA policy was cancelled. The accuracy of / A code for single-point positioning is increased from 100 meters to 10 meters, which will further promote the application of GPS technology, improve productivity, operating efficiency, scientific level and people's quality of life, and stimulate the growth of the GPS market. According to relevant experts' predictions, in the United States, the car GPS navigation system alone will have a market of $ 3 billion after 2000, and in China, the car navigation market will also reach 5 billion yuan. It can be seen that the application prospect of the GPS technology market is very considerable.
