satvis：使用Cesium.js进行卫星轨道可视化和通过预测

# [satvis.space](https://satvis.space)  Satellite orbit visualization and pass prediction.  ## 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 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). <p align="center"><a href="https://apps.apple.com/app/satvis/id1441084766"><img src="src/assets/app-store-badge.svg" width="250" /></a></p> ## License This project is licensed under the MIT License - see `LICENSE` file for details. ## Acknowledgements Inspired by a visualization developed for the [MOVE-II CubeSat project](https://www.move2space.de) by Jonathan, Marco and Flo.
