Why does a GPS navigator work unreliably in a moving vehicle under a bridge or overpass?

GPS (Global Positioning System) navigators rely on signals from satellites to determine the device's location. However, there are several factors that can affect the reliability of GPS signals in certain situations, such as when a vehicle is moving under a bridge or overpass. Here are a few reasons why GPS navigators may work unreliably in such scenarios:

1. Signal obstruction: Bridges and overpasses are typically constructed with materials that can block or weaken GPS signals. These materials, such as concrete or steel, can attenuate the signals, making it difficult for the GPS receiver to receive accurate location data.

2. Multipath interference: When a GPS signal encounters obstacles like bridges or overpasses, it can bounce off these surfaces and create multiple signal paths. This phenomenon is known as multipath interference. When the GPS receiver receives these multiple signals, it can lead to inaccuracies in determining the device's location.

3. Signal reflection: Bridges and overpasses can reflect GPS signals, causing the receiver to receive delayed or distorted signals. This can also contribute to inaccuracies in determining the device's location.

It's important to note that GPS technology has improved over the years, and newer GPS receivers may be better equipped to handle these challenges. However, in certain situations, such as when a vehicle is moving under a bridge or overpass, the reliability of GPS signals can still be affected.
