In what weather conditions is GPS operational?

GPS is operational in all weather conditions because it relies on signals transmitted from satellites in orbit around the Earth. These satellites send signals that are not significantly affected by weather phenomena like rain, clouds, fog, or snow. The satellite signals can penetrate through most atmospheric conditions, enabling consistent positioning and navigation services.

This capability is crucial for various maritime operations, as it ensures that vessel crews can rely on GPS technology for navigation regardless of the environmental circumstances they may face. The functionality of GPS is a key element of modern navigation, making it an essential tool for boat crew members operating under diverse weather scenarios.
