The BATH alignment is available only beyond which latitudes?

The BATH alignment, which stands for Background Automated Tactical Hand-off, becomes available only beyond 78 degrees latitude. This alignment is utilized for specific operations that require refinement of data related to navigation and tactical information at high latitudes, where standard systems may not function optimally due to the Earth's curvature and the limitations of GPS and other navigation aids.

At latitudes below 78 degrees, various factors, including the satellite coverage patterns and the geometry of navigation aids, can hinder effective alignment. Therefore, operations conducted at higher latitudes, particularly those above 78 degrees, allow for the use of the BATH alignment to enhance situational awareness and navigation accuracy. This is crucial for mission profiles that involve extreme northern routes, particularly those that may be mission-sensitive or require precision in challenging environments.
