## Description

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.

## Tools

### calculate_sight_reduction
Calculates the intercept and true azimuth for a celestial body sight

### get_correction_factors
Retrieves the necessary atmospheric and physical correction values for a specific observation

### verify_position_validity
Validates if an assumed position is geographically plausible for the given observation

## Prompt Examples

**Prompt:** 
```
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.
```

**Response:** 
```
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.
```

**Prompt:** 
```
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.
```

**Response:** 
```
The position and altitude are valid for this observation.
```

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

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

## Frequently Asked Questions

**What is a sight reduction?**
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.

**How do I handle atmospheric corrections?**
You can use the `get_correction_factors` tool to retrieve specific values for dip, refraction, parallax, and semidiameter based on your observation.

**Can I use this for Moon observations?**
Yes, the tool supports the Sun, Moon, and stars, including specific parallax corrections required for lunar observations.
