## What it is
KeepTrack is a TypeScript astrodynamics application that provides real-time 3D visualization of 50,000+ satellites and millions of debris objects in the browser using custom WebGL 2.0 shaders and an internal orbital mechanics library. It runs offline, requires no installation, and includes sensor simulation, breakup event modeling, and launch visualization for students, educators, and operations centers.

## Use cases
- track satellites in real time in a 3D browser view
- visualize space debris and breakup events
- simulate ground sensor coverage and visibility of satellites
- learn orbital mechanics without an engineering background
- visualize a new rocket launch from any Earth location
- run an offline satellite tracking tool in restricted environments
- analyze debris patterns around specific orbits

## When to choose
- you need a free, browser-based 3D satellite tracker that runs offline
- you are teaching or learning orbital mechanics and satellite operations
- you want to simulate sensors, launches, or debris breakups visually
- you need to track tens of thousands of objects at high frame rates

## When to avoid
- you need a headless orbital propagation library for backend computation rather than a visual app
- you require official mission-planning-grade astrodynamics certification or precision ephemeris generation
- you need a native desktop or mobile app rather than a web application

## Facets
- artifact type: application
- maturity: active
- function: simulation, data-visualization, graphics, search-engine
- domain: astronomy, simulation, data-visualization, education
- platform: browser, cross-platform
- tags: satellite-tracking, orbital-mechanics, astrodynamics, webgl, space-debris, 3d-visualization, space-surveillance, web-server, typescript
