It also demonstrates how **MemgraphDB** can be used to find the shortest routing path in such networks.\u003cbr /\u003e\nTo find out more about the subject, read the accompanying [blog post](https://github.com/memgraph/starlink/blob/master/blog_post/blog-post.md).\n\n\u003cbr /\u003e\n\u003cp align=\"center\"\u003e\n   \u003cimg src=\"https://raw.githubusercontent.com/g-despot/images/699ee65713223a90af3f5b180f331893b2c469be/demo_screenshot.png\" alt=\"\" width=\"800\"/\u003e\n\u003cp/\u003e\n\u003cbr /\u003e\n\n\u003e [!NOTE]  \n\u003e We no longer host the Starlink Simulator app on `http://starlink.memgraph.com/`. You can still check out this project to learn how to build an app with Memgraph.\n\n## Prerequisites\n\nBefore you can run the application, you need to have the following tools installed:\n* [Docker](https://docs.docker.com/get-docker/)\n* [Docker Compose](https://docs.docker.com/compose/install/)\n\nAfter you installed Docker you need to download the [Memgraph image](https://memgraph.com/download) for Docker and [load it](https://docs.memgraph.com/memgraph/quick-start#docker-installation).\u003cbr /\u003e\nThe container with the image should be stopped before attempting to build and run the app.\n\n## Start the app\n\nFirst, position yourself in the root folder of the project. Build the Docker image and run the application with the following commands:\n```\ndocker-compose build\ndocker-compose up\n```\nIf everything was successful you can open it in your browser. The app will be listening on: http://localhost:5001/. \n\n## Project structure\n\nThe app is divided into three separate modules:\n* **memgraph** - the database where all the positions of satellites and cities are stored and updated. \n* **simulator** - a Python program that utilizes the Skyfield package to calculate satellite positions in orbit. Those positions are then stored in the Memgraph database.\n* **web_app** - a client-server app that fetches data from the database and renders it.\n\n## Technologies used\n\n* Python 3.7\n* MemgraphDB 2.2.1\n* Apache Kafka\n* Poetry\n* Skyfield\n* Flask\n* Leaflet\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmemgraph%2Fstarlink","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmemgraph%2Fstarlink","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmemgraph%2Fstarlink/lists"}
