Store description excerpt
Ixelan puts a fully physics-accurate orbital laboratory in your pocket. Choose from twelve hand-crafted fictional worlds — each with its own gravitational parameter, rotation period, and optional moon — then place a satellite in orbit and watch real astrodynamics unfold in real time. Three interchangeable numerical integrators (Velocity Verlet, Symplectic Euler, and RK2) drive the simulation, giving you a transparent look at how the math works under the hood. Drag the satellite glyph to apply a delta-v burn, review the predicted apoapsis, periapsis, and eccentricity before committing, and manage your total delta-v budget across every mission. Crank time warp up to 1000x to watch long-period orbits in seconds, or slow it right down to nail a precise maneuver. The Orbit Sandbox tracks every burn and reports the instant your satellite escapes to infinity or spirals in and impacts the surface. The Transfer Planner puts Hohmann and bi-elliptic transfer calculations at your fingertips. Dial in your start and target radii, see the required delta-v and transfer time instantly, and explore the full delta-v curve on a scrubable chart before committing the maneuver to your budget. Every completed run and committed transfer is saved automatically to your Mission Log, where you can search, sort, pin, and annotate entries — even attach a photo as a mission observation. Telemetry plots altitude, speed, and specific orbital energy across the last run, with a scrubable crosshair for precise readback. The Body Catalogue lets you compare surface gravity across up to five worlds side by side. Whether you are a student exploring Kepler's laws for the first time or an enthusiast who already knows what bi-elliptic means, Ixelan makes orbital mechanics tangible, interactive, and genuinely rewarding.
