### Orbital Simulator

Orbital navigation is mainly done by transferring from one orbit to another, contrary to how we drive on Earth, where we simply accelerate and turn the wheel into the direction we want to go.

The orbital simulator (developed for DTU Space / rummet.dk) lets students understand basic orbital properties, such as orbital periods, orbital velocities, delta-v and hohmann transfers.

Because of the target-audience, everything is very simplified. The goal is to intersect a randomly placed satellite without running out of fuel. The height of the satellite is unknown, and to match position, the student must understand how you overtake an object even if you are in the correct orbit yourself.
