Static positioning types include global satellite navigation system, cellular network positioning, Wi-Fi positioning, Bluetooth positioning, RFID positioning, optical positioning, ultrasonic positioning and magnetic field positioning, etc. Detailed introduction: 1. Global satellite navigation system is a positioning technology based on satellite signals, the most famous of which is the global positioning system. By receiving signals from satellites, the receiving device can calculate the position coordinates of the receiver; 2. Cellular Network positioning is a technology that uses signals from mobile communication base stations to determine the location of a device, by measuring the signal strength between the device and the base station, etc.
The operating system for this tutorial: Windows 10 system, DELL G3 computer.
Static positioning refers to determining the location information of an object or individual by using sensors or other devices without moving. Static positioning can be classified according to different technical principles and application fields. The following are some common types of static positioning:
1. Global Satellite Navigation System (GNSS): The Global Satellite Navigation System is a system based on satellite signals. Positioning technology, the most famous of which is the Global Positioning System (GPS). By receiving signals from satellites, the receiving device can calculate the location coordinates of the receiver. GNSS static positioning is widely used in navigation, map production, resource management, environmental monitoring and other fields.
2. Cellular network positioning: Cellular network positioning is a technology that uses signals from mobile communication base stations to determine the location of a device. The location of a device can be estimated by measuring the signal strength, time difference of arrival, or other parameters between the device and the base station. Cellular network positioning is commonly used in fields such as mobile phone positioning, emergency positioning and location services.
3. Wi-Fi positioning: Wi-Fi positioning is a technology that uses Wi-Fi signals to determine the location of a device. The device's location is determined by scanning surrounding Wi-Fi networks and matching against a pre-built Wi-Fi database. Wi-Fi positioning is commonly used in indoor positioning, shopping mall navigation and location services.
4. Bluetooth positioning: Bluetooth positioning is a technology that uses Bluetooth signals to determine the location of a device. The device's location can be determined by scanning for surrounding Bluetooth devices and matching against a pre-established Bluetooth database. Bluetooth positioning is commonly used in areas such as indoor navigation, smart homes, and item tracking.
5. RFID positioning: RFID (Radio Frequency Identification) positioning is a technology that uses radio signals for object identification and location tracking. By implanting or attaching RFID tags to objects and using readers and writers to read the information on the tags, the location of the object can be determined. RFID positioning is commonly used in fields such as logistics management, warehouse management and asset tracking.
6. Optical positioning: Optical positioning is a technology that uses optical sensors and image processing technology to determine the position of objects. The location of an object can be determined by analyzing its visual characteristics, such as color, texture, and shape. Optical positioning is commonly used in fields such as indoor navigation, virtual reality, and industrial automation.
7. Ultrasonic positioning: Ultrasonic positioning is a technology that uses ultrasonic signals to determine the location of objects. By sending and receiving ultrasonic signals, and based on the signal's propagation time and reflection principles, the position of the object can be determined. Ultrasonic positioning is commonly used in indoor positioning, smart home and security systems and other fields.
8. Magnetic field positioning: Magnetic field positioning is a technology that uses the characteristics of the earth's magnetic field to determine the location of objects. By measuring the strength of the magnetic field around an object and analyzing the magnetic field data, the location of the object can be determined. Magnetic field positioning is commonly used in indoor navigation, underground pipeline detection, geological exploration and other fields.
In short, static positioning can be classified according to different technical principles and application fields, including global satellite navigation system, cellular network positioning, Wi-Fi positioning, Bluetooth positioning, RFID positioning, optical positioning, ultrasonic Positioning and magnetic field positioning, etc. These positioning technologies are widely used in navigation, geographic information systems, indoor positioning, smart homes, logistics management and security systems.

React's componentized architecture makes scalable UI development efficient through modularity, reusability and maintainability. 1) Modularity allows the UI to be broken down into components that can be independently developed and tested; 2) Component reusability saves time and maintains consistency in different projects; 3) Maintainability makes problem positioning and updating easier, but components need to be avoided overcomplexity and deep nesting.

React's one-way data binding ensures that data flows from the parent component to the child component. 1) The data flows to a single, and the changes in the state of the parent component can be passed to the child component, but the child component cannot directly affect the state of the parent component. 2) This method improves the predictability of data flows and simplifies debugging and testing. 3) By using controlled components and context, user interaction and inter-component communication can be handled while maintaining a one-way data stream.
