GPS signal interference mainly includes the following types:

Natural factors

1. Atmospheric conditions: Natural phenomena such as solar storms and ionospheric disturbances may affect the propagation of GPS signals.
2. Geographic environment: Obstacles such as mountains, buildings, and trees may obstruct or reflect GPS signals. Causing signal attenuation or distortion.

human factor

1. GPS jammer: It can transmit signals of the same frequency as GPS signals to interfere or deceive GPS receivers. Causing the receiver to be unable to receive or parse GPS signals correctly.
2. Electromagnetic interference: Strong electromagnetic field sources, such as high-voltage wires, large motors, wireless communication equipment, etc. May cause electromagnetic interference, affecting the reception of GPS signals.

Technical defects

1. Equipment aging: The aging of GPS receivers or related devices may lead to a decrease in signal processing capabilities, making it difficult to effectively receive or analyze GPS signals.
2. Software issue: The software algorithm of the GPS receiver may have defects and cannot process signals correctly, resulting in signal loss or errors.

Improper operation

1. Improper installation position: If the GPS receiver is installed in a location with signal obstruction, such as an internal corner or metal container, it may receive weak or distorted signals.
2. Power supply issue: An unstable or incorrect power supply may affect the normal operation of the GPS receiver, leading to signal loss.

To avoid interference with GPS signals, some measures can be taken, such as optimizing the installation location of the equipment, using high-quality GPS receivers, regularly maintaining and upgrading the equipment, and avoiding the use of GPS equipment in strong electromagnetic interference environments.
