SatRadar is a satellite tracking reference app for iOS that visualizes real-time orbital telemetry for over ten thousand spacecraft.
The App DNA
What makes this app unique?
The app removes the performance friction found in standard orbital viewers, allowing users to visualize complex constellations without the frame-rate drops that typically occur at high object counts.
For Space enthusiasts, amateur astronomers, and users interested in real-time orbital mechanics and satellite constellations.
What does it look like?
Key features
Custom GPU-side SGP4 orbital propagation allows rendering ten thousand satellites at 60-120 frames per second.
Interactive timeline slider allows users to view orbital history from 1957 to the present day.
Visualizes the full Starlink constellation including laser cross-links between satellites.
How much does it cost?
Freemium model relies on two optional one-time purchases rather than subscriptions, targeting long-term utility without recurring costs.
