About

Orbiting Radio Star is a collection of short browser games about satellites, orbits and radio. Each game runs on a simplified model of real physics, and the theory pages explain what is being modeled.

The name comes from the book Satellite Technology: Principles and Applications, by Anil K. Maini and Varsha Agrawal (Wiley, 3rd edition). There, the satellite is called an “orbiting radio star”, a radio star in orbit that helps ships and aircraft navigate safely in any weather.

The games here start from that idea: the satellite as a reference point in the sky.
