How can inaccuracies in electronic navigational instruments affect a voyage?

Inaccuracies in electronic navigational instruments can significantly impact a voyage by leading to miscalculations of position and course. When the data provided by instruments such as GPS, radar, or electronic chart display systems is incorrect or unreliable, navigators may incorrectly perceive their vessel's location or intended trajectory. This can result in various navigational errors, such as drifting off course, which might lead to unsafe navigation through hazardous waters or failure to reach a destination on time. Moreover, these miscalculations can increase the risks of collisions with other ships or underwater obstacles, jeopardizing not only the vessel and crew but also the environment. Consequently, accuracy in electronic navigation is critical for safe and efficient maritime operations.
