Galileo Tracker

Galileo is a basic object tracker inspired by sites such as SatelliteTracker3D, StarlinkMap, and KeepTrack. Galileo currently uses satellite.js and its SGP4 calculations for forward and backward object propogation. It is designed for flexible development, and with a smooth user experience in mind.

Galileo is built using ES2020 and Vite. To run locally, install git and node.

Set up a Local Copy

git clone https://github.com/speer-ai/galileo-app         # Clone files to local
cd ./galileo-app/                                         # Switch into the directory
npm install                                               # Install dependencies

then either

npm run dev                                               # Run a hot dev version

or

npm run build                                             # Build the project
npm start                                                 # Start the server

to start a copy.

Interface and Usage

Galileo displays a fullscreen rendering of earth and sattelites using @react-three-fiber and Tailwind.css to style the page. Galileo allows for past & future date manipulation and provides many keyboard shortcuts for users to navigate between objects. Galileo features other visuals such as orbit displays, a dynamic hexasphere, and more.

Possible Future Updates

Galileo may be updated in the future to allow use with live sensors & data and/or the ability to control local communication devices.

• Hook up live feed (camera maybe)
• Control physical antenna
• Detect, track, and predict trajectories of objects (not necessary satellites)

Bugs & Inefficiencies

• At certain angles, all objects will disappear from view (likely not in frustrum)

• Object corner textures visible at certain angles

• Switch time zone?

• Some calculations redundant

• Can't enter date manually into panel

• Request location from user automatically?

• Switch between ECI / ECF coordinates
