This repository was created by Brian Donald, Bryan Pikaard, Zach Stence, and Andreas Wenzel for SpaceApps 2021.

The Orbital Tracker uses TLE data to calculate and interpolate the position of objects orbiting earth, and then renders them in a web page that makes the data more accessible and interactive. You can view a live link at https://2021.spaceapps.sprocket.gg.

Building and Running Locally

1. Clone the repository
2. To run the SvelteKit application
   1. npm i in the svelte directory
   2. npm run dev in the svelte directory
   3. Open localhost:3000
3. To run/build the C++ application
   Note: The build script for wasm assumes that you are on a unix-like system, with access to sed
   1. Ensure you have the EMScripten SDK installed (if working with the C++ portion)
   2. Run build.sh in the wasm directory.
