How to use Orbit Lab
New to Orbit Lab? Build a satellite’s orbit and watch it fly in real time.• Start from a preset (LEO, GEO, Molniya…) or set the six orbital elements — a, e, i, Ω, ω, ν — with the sliders, or type exact values.• Switch between the 3D globe and the 2D groundtrack with the buttons just below.• Press Play to animate the orbit and watch the live stats in the readouts panel on the right.• Save a labeled snapshot anytime with Export image.
