Which celestial navigation software is utilized by the U.S. Navy?

The U.S. Navy utilizes STELLA as its celestial navigation software because it is specifically designed to facilitate precise celestial navigation. STELLA provides advanced features that allow for accurate celestial positioning and timekeeping, essential for maritime operations where traditional navigation methods may not be feasible or safe. Its capabilities support the U.S. Navy in complex navigation tasks and training simulations, making it a vital tool for personnel in navigating in open ocean environments, especially when GPS is unreliable or compromised. The software's comprehensive modeling of celestial mechanics enhances decision-making for naval operations, demonstrating a strong alignment with the Navy's need for accuracy and reliability in navigation.
