What are the faults of absolute positioning?

Absolute positioning faults include: 1. Positioning signal loss; 2. Receiver software or hardware failure; 3. Interference; 4. Signal propagation delay; 5. Multipath effect; 6. Hardware configuration error; 7. Software configuration errors; 8. Data processing errors; 9. External interference, etc. Detailed introduction: 1. The positioning signal is lost. The absolute positioning system needs to receive satellite signals to determine the position. If the receiver cannot receive enough satellite signals, or the received signal quality is poor, causing the position information to be unable to be determined, a positioning failure will occur. ;2. Receiver software or hardware failure, etc.

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

Absolute positioning failures may include the following situations:

1. Positioning signal loss: The absolute positioning system needs to receive satellite signals to determine the position. Positioning failures can occur if the receiver cannot receive enough satellite signals, or if the quality of the received signals is poor so that the location information cannot be determined. This could be due to satellite failure, receiver failure, or signal propagation issues.

2. Receiver software or hardware failure: The receiver of the absolute positioning system may have software or hardware failure, resulting in the inability to receive and process satellite signals normally, making it impossible to determine position information. This may require receiver replacement or repair.

3. Interference: The absolute positioning system may be affected by electromagnetic interference, signal conflicts or other factors, causing it to fail to work properly. For example, nearby radio transmitting equipment, buildings or other objects may interfere with the propagation of satellite signals, causing positioning failures.

4. Signal propagation delay: The satellite signal of the absolute positioning system takes time to propagate. If the distance between the receiver and the satellite is far, or the signal is refracted or reflected when propagating through the atmosphere or high-rise buildings, it may It will cause signal propagation delay, thus affecting positioning accuracy.

5. Multipath effect: When satellite signals pass through buildings, woods or other obstacles, multipath effects may occur, causing the receiver to receive multiple copies of satellite signals, thus affecting positioning accuracy. This may require taking steps to eliminate multipath effects, such as choosing a suitable reception location or using techniques that are resistant to multipath effects.

6. Hardware configuration error: The hardware configuration error of the absolute positioning system may cause the system to fail to work properly. For example, incorrect connection between the receiver and the satellite, poor connection of the power line or signal line, etc. may cause positioning failure.

7. Software configuration errors: Software configuration errors of the absolute positioning system may cause the system to fail to work properly. For example, incorrect system parameter settings, incompatible software versions, etc. may cause positioning failures.

8. Data processing errors: The absolute positioning system may have errors during data processing, resulting in inaccurate final positioning results. For example, data processing algorithm errors, data transmission errors, etc. may cause positioning failures.

9. External interference: The absolute positioning system may be affected by external interference, such as lightning, electromagnetic pulse and other natural phenomena, causing the system to fail to work properly. This may require measures to protect the system from external interference.

It should be noted that the specific manifestations of absolute positioning faults may vary depending on different systems and applications. Therefore, when a location fault occurs, it is necessary to analyze and troubleshoot according to the specific situation to find out the cause of the fault and take corresponding solutions.
