What are the causes of absolute positioning failures?

The reasons for absolute positioning failure are: 1. Poor satellite signal reception; 2. Signal propagation problem; 3. Receiver failure; 4. Interference; 5. Multipath effect; 6. Hardware configuration error; 7. Software configuration error; 8. Data processing error; 9. External interference; 10. Satellite failure, etc. Detailed introduction: 1. Poor satellite signal reception. The absolute positioning system determines position information by receiving satellite signals. If the receiver cannot receive a sufficient quantity or quality of satellite signals, it will cause the position to be unable to be determined normally and a positioning failure will occur; 2 , signal propagation issues, etc.

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

Absolute positioning failure may be caused by the following reasons:

1. Poor satellite signal reception: The absolute positioning system determines position information by receiving satellite signals. If the receiver cannot receive a sufficient quantity or quality of satellite signals, it will not be able to determine the position normally and a positioning failure will occur. For example, the receiver antenna may be blocked, interfered with, or moved, affecting reception of satellite signals.

2. Signal propagation problem: During the propagation process, satellite signals may be affected by natural or man-made factors such as the atmosphere, high-rise buildings, forests, etc., resulting in signal propagation delays, refraction or reflection, thus affecting the receiver's Determination of location information. For example, in certain environments such as urban high-rise buildings or mountainous canyons, satellite signals may be greatly affected, leading to positioning failures.

3. Receiver failure: The receiver of the absolute positioning system may have hardware or software failures, resulting in the inability to receive and process satellite signals normally, making it impossible to determine position information. For example, the receiver antenna may be damaged, there may be a problem with the receiver circuitry, or the receiver software may be buggy or incompatible with the satellite system.

4. 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, electronic equipment or large electrical equipment may produce electromagnetic interference, affecting the reception and propagation of satellite signals; at the same time, signal conflicts from other radio equipment may also interfere with the normal operation of the absolute positioning system.

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 be related to factors such as the surrounding environment, receiver configuration, or signal propagation characteristics.

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. Therefore, you need to carefully check whether the hardware connections are correct when installing and configuring the absolute positioning system.

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. Therefore, when using the absolute positioning system, you need to carefully check whether the software configuration is correct and follow the relevant instructions to set it up.

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. This may require checking that data processing procedures and algorithms are correct.

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 taking measures to protect the system from external interference, such as using lightning protection equipment, improving the electromagnetic compatibility of the system, etc.

10. Satellite failure: The satellite itself may also fail, causing the quality of the signal sent to decrease or losing contact, thus affecting the normal operation of the absolute positioning system. This may require prompt contact with relevant agencies or emergency measures to be taken.

It should be noted that different absolute positioning systems and application scenarios may have different failure causes and manifestations. Therefore, when encountering an absolute positioning fault, it is necessary to analyze and troubleshoot according to the specific situation, find out the specific cause of the fault and take corresponding solutions. At the same time, in order to reduce the risk of failure, it is also necessary to pay attention to system maintenance and maintenance, regular inspection of hardware and software configuration and other measures.
