Satellite MCP Server

A comprehensive Model Context Protocol (MCP) server for satellite orbital mechanics calculations with natural language processing capabilities.

- 🛰️ Satellite Access Window Calculations- Calculate when satellites are visible from ground locations
- 🌍 World Cities Database- Built-in database of 200+ cities worldwide for easy location lookup
- 🗣️ Natural Language Processing- Parse orbital parameters from text like "satellite at 700km in SSO over London"
- 📡 TLE Generation- Generate Two-Line Elements from orbital descriptions
- 🌅 Lighting Analysis- Ground and satellite lighting conditions (civil, nautical, astronomical twilight)
- 📊 Bulk Processing- Process multiple satellites and locations from CSV data
- 🚀 6 Orbit Types- Support for LEO, MEO, GEO, SSO, Molniya, and Polar orbits

# Clone the repository git clone <repository-url> cd mcp-orbit # Build the Docker image make docker-build # Run the MCP server make docker-run

# Install dependencies make install # Run the MCP server make run

The server communicates via JSON-RPC 2.0 over stdio. Here are the connection methods:

Add to your Claude Desktop MCP configuration file:

macOS:~/Library/Application Support/Claude/claude_desktop_config.jsonWindows:%APPDATA%/Claude/claude_desktop_config.json

{ "mcpServers": { "satellite-mcp-server": { "command": "docker", "args": ["run", "--rm", "-i", "satellite-mcp-server:latest"] } } }

# Interactive mode docker run -it --rm satellite-mcp-server:latest # Pipe commands echo '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | \ docker run --rm -i satellite-mcp-server:latest

# If running locally without Docker python -m src.mcp_server

Example 1: Basic Satellite Pass Prediction

"When will the ISS be visible from London tomorrow?"

{ "tool": "calculate_access_windows_by_city", "arguments": { "city_name": "London", "tle_line1": "1 25544U 98067A 24001.50000000 .00001234 00000-0 12345-4 0 9999", "tle_line2": "2 25544 51.6400 123.4567 0001234 12.3456 347.6543 15.49011999123456", "start_time": "2024-01-02T00:00:00Z", "end_time": "2024-01-03T00:00:00Z" } }

Response:The ISS will be visible from London 4 times tomorrow, with the best pass at 19:45 UTC reaching 78° elevation in the southwest sky during civil twilight.

Example 2: Natural Language Orbital Design

"Create a sun-synchronous satellite at 700km altitude and show me when it passes over Tokyo."

{ "tool": "parse_orbital_elements", "arguments": { "orbital_text": "sun-synchronous satellite at 700km altitude" } }

{ "tool": "calculate_access_windows_from_orbital_elements_by_city", "arguments": { "orbital_text": "sun-synchronous satellite at 700km altitude", "city_name": "Tokyo", "start_time": "2024-01-01T00:00:00Z", "end_time": "2024-01-02T00:00:00Z" } }

Response:Generated SSO satellite (98.16° inclination, 98.6 min period) with 14 passes over Tokyo in 24 hours, including 6 daylight passes and 8 during various twilight conditions.

"I have a CSV file with ground stations and want to analyze coverage for multiple satellites."

{ "tool": "calculate_bulk_access_windows", "arguments": { "locations_csv": "name,latitude,longitude,altitude\nMIT,42.3601,-71.0589,43\nCaltechm,34.1377,-118.1253,237", "satellites_csv": "name,tle_line1,tle_line2\nISS,1 25544U...,2 25544...\nHubble,1 20580U...,2 20580...", "start_time": "2024-01-01T00:00:00Z", "end_time": "2024-01-02T00:00:00Z" } }
