This MCP server provides precise tools for celestial navigation. It allows AI agents to perform sight reduction by calculating the intercept and true azimuth from observed celestial bodies like the Sun, Moon, or stars. Using calculate_sight_reduction, agents can determine the distance from an assumed position. The server also provides get_correction_factors to account for atmospheric dip, refraction, parallax, and semidiameter, and verify_position_validity to ensure geographical plausibility of observations.

Calculate the intercept and azimuth for the Sun at 45.0 N, 30.0 W, with an observed altitude of 40.0 degrees and GHA of 120.0 degrees and declination of 15.0 degrees.

The calculated altitude (Hc) is 38.45 degrees, the intercept is 12.5 nautical miles towards the Sun, and the true azimuth (Zn) is 145.2 degrees.

Check if an observation of a star at 10.0 degrees altitude is valid for a position at 0.0 latitude and 0.0 longitude.

The position and altitude are valid for this observation.

What are the correction factors for a Moon observation at 20 degrees altitude with an eye height of 5 meters?

The correction factors are: dip: -0.04 degrees, refraction: 0.03 degrees, parallax: 0.01 degrees, and semidiameter: 0.26 degrees.

Sight reduction is the process of calculating the intercept and azimuth to determine a vessel's position based on the observed altitude of a celestial body.
