A satellite visualization tool designed to transform Two-Line Element (TLE) sets into intuitive, interactive data. Track the past, current and future positions of satellites, Earth, and the Moon across 3D and 2D environments.
Seamlessly toggle between an interactive 3D orbital space and a 2D projection featuring accurate satellite ground tracks.
Easily preview sunlight conditions, in 2D and 3D simulation environments. The simulation goes beyond *just* drawing the terminator line.
Real-time rendering of Line-of-Sight (LOS) coverage areas and comprehensive orbital characteristics.
Efficiently load and parse TLE data for individual satellites or entire constellations.
Equipped with tools designed for RF engineers, satellite operators, and enthusiasts wanting to know when to expect the next sunlit ISS pass.
Developed in pure C utilizing the Raylib framework. Offers high-performance rendering capable of handling thousands of satellites efficiently.
