What are the methods of fixed positioning?

Fixed positioning methods include fixed GPS positioning, fixed base station positioning, fixed WiFi positioning, fixed camera positioning, fixed sensor positioning, etc. Detailed introduction: 1. Fixed GPS positioning: Install the GPS receiver at a fixed location and determine the longitude and latitude coordinates of the location by receiving satellite signals. This method is often used in fields such as surveying and mapping, geographic information systems; 2. Fixed base station positioning: multiple base stations are arranged in a specific area, and each base station has known location information. This method is often used in indoor positioning, wireless communications and other fields; 3. Fixed WiFi positioning, etc.

Fixed positioning refers to the acquisition and positioning of location information by installing positioning equipment or sensors in fixed locations. The following are several common fixed positioning methods:

1. Fixed GPS positioning: Install the GPS receiver at a fixed location and determine the longitude and latitude coordinates of the location by receiving satellite signals. This method is often used in fields such as surveying and mapping, geographic information systems, etc.

2. Fixed base station positioning: Multiple base stations are deployed in a specific area, and each base station has known location information. By receiving the signal sent by the mobile device or receiver, the signal strength, arrival time difference and other parameters are calculated to determine the location of the device. This method is commonly used in indoor positioning, wireless communications and other fields.

3. Fixed WiFi positioning: Deploy multiple WiFi access points in a specific area and establish a WiFi signal database. The location of the device is determined by receiving WiFi signals sent by the device and matching them with the database. This method is often used in indoor positioning, location services and other fields.

4. Fixed camera positioning: Fix the camera at a specific location, and determine the location of the object or device by processing and analyzing feature points, landmarks or images in the scene. This method is often used in fields such as video surveillance and robot navigation.

5. Fixed sensor positioning: Install sensors (such as laser sensors, ultrasonic sensors, etc.) at fixed locations, and determine location information by measuring the physical characteristics of the surrounding environment, such as distance, sound, etc. . This method is often used in environmental monitoring, smart buildings and other fields.

The above are some common fixed positioning methods, each method has its applicable scenarios and characteristics. According to specific application requirements and environmental conditions, selecting an appropriate fixed positioning method can achieve accurate and reliable location information acquisition.
