What is STELLA used for?

Explanation:
STELLA is used for celestial navigation. It helps a navigator determine the ship’s position at sea by processing sightings of celestial bodies (like the sun or stars) taken with a sextant and converting those observations into a line of position, which is then plotted to fix the vessel’s location. The program handles the math of sight reductions, time adjustments, and plotting, making it practical to practice or verify celestial navigation without doing all the manual calculations by hand. This is what makes it the best choice for the question. The other options don’t fit STELLA’s purpose: it’s not a general test tool, a boat-maintenance program, or a weather-forecasting system.
