satvis.space

Satellite orbit visualization and pass prediction.

Note

The next branch contains many improvements from a bigger refactoring and is the recommended branch currently. This version is currently deployed to satvis.space. Planning to merge this back to the master main in the next few months.

Features

• Calculate position and orbit of satellites from TLE
• Set groundstation through geolocation or pick on map
• Calculate passes for a set groundstation
• Local browser notifications for passes
• Serverless architecture
• Works offline as Progressive Web App (PWA)

Built With

• CesiumJS
• Satellite.js
• Vue.js
• Workbox

Development

Setup

Initialize submodules and install npm build dependencies:

git submodule update --init
mise install         # provision Node 24 + pnpm 11 (see mise.toml); or bring your own
pnpm install

A single pnpm install at the repository root installs dependencies for both the SPA and the worker/ package.

Run

• pnpm start for the dev server
• pnpm build to build the application (output in dist folder)
• pnpm serve to build the application and serve with static webserver
• pnpm update-tle to retrieve the latest satellite TLEs from NORAD

iOS App

To provide pass notifications on iOS where local browser notifications are not supported a simple app wraps the webview and handles the scheduling of UserNotifications.
