Privateer Space’s Wayfinder app uses CesiumJS to provide open access and near real-time visualization of tracked objects in Earth’s orbit. Wayfinder includes space object visualization, trajectory analysis, and collision prediction services for space operators, academic researchers, and citizens. The app aggregates data from a variety of sources, which are used to produce a single cohesive map of space objects. This dynamic data is displayed as points in CesiumJS at runtime, accurately showing the positions of satellites and tens of thousands of pieces of space junk in near real time.
