## 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](https://cesiumjs.org)
- [Satellite.js](https://github.com/shashwatak/satellite-js)
- [Vue.js](https://vuejs.org)
- [Workbox](https://developers.google.com/web/tools/workbox)

## Development

### Setup
Initialize submodules and install npm build dependencies:
```
git submodule update --init
npm clean-install
```

### Run
- `npm run start` for the dev server
- `npm run build` to build the application (output in `dist` folder)
- `npm run serve` to build the application and serve with static webserver
- `npm run 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](https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API#Browser_compatibility)
a simple app wraps the webview and handles the scheduling of
[UserNotifications](https://developer.apple.com/documentation/usernotifications).
