Absolute positioning technology refers to determining the precise location of objects by using satellites, ground base stations or other equipment. The following are several common absolute positioning technologies:

1. GPS (Global Positioning System): GPS is a satellite navigation system that can determine the location of objects by receiving signals from satellites. The GPS system was developed by the U.S. government and has now become the standard for global positioning technology.

2. GLONASS: GLONASS is a Russian satellite navigation system, similar to GPS. It consists of a constellation of satellites that provide location information similar to GPS.

3. Beidou Navigation System: Beidou Navigation System is China’s satellite navigation system, similar to GPS and GLONASS. It consists of a constellation of satellites that provide global positioning services.

4. Base station positioning: Base station positioning is a technology that uses ground base stations to determine the location of objects. When a device communicates with a base station, the base station can determine the device's location.

5. RFID (Radio Frequency Identification): RFID is a technology that uses radio frequency signals to identify objects. By placing RFID tags on objects, the location of the object can be determined.

6. Bluetooth positioning: Bluetooth positioning is a technology that uses Bluetooth signals to determine the location of objects. By placing a Bluetooth tag on an object, the location of the object can be determined.

These technologies can be used alone or in combination to provide more accurate location information. They are widely used in many fields, including logistics, transportation, security, military, medical and entertainment, etc.
