In navigation terms, what is the definition of an EPOCH?

The definition of an EPOCH in navigation terms pertains to its role as a time reference for navigation systems. In this context, an EPOCH is typically a specific point in time that can be used as a reference for various calculations or processes within navigation systems. This can include the synchronization of GPS signals, the timing of data recordings, or the reference for waypoint coordinates.

Having precise timing information is crucial for accurate navigation and positioning, as it helps ensure that all data is aligned and relevant to a common temporal reference. By understanding the concept of an EPOCH, aviators and navigators can better utilize modern navigation technologies that rely on accurate timekeeping to provide positional information.
