A STARTING POINT, MADE FOR YOU
The orbital mechanics learner
toolbox.
Explore ideal rocket mass ratios, circular orbits and two-burn transfers.
INSIDE THE TOOLBOX
Starter collection8 useful places to start.
Two-body and ideal-burn models exclude atmosphere, perturbations, staging and mission constraints.
Ideal rocket delta-v
Relate mass ratio and specific impulse to ideal velocity change.
Ideal circular orbit
Calculate circular speed, period and local escape speed around a supplied central mass.
Coplanar Hohmann transfer
Compare ideal tangential impulses and coast time between two circular orbits.
3D vector calculator
Calculate lengths, dot and cross products, angle and vector projection.
3D Euler rotation workspace
Apply an explicit X–Y–Z rotation order and inspect the resulting matrix.
Quaternion vector rotation
Normalise a Hamilton quaternion and use it to rotate a 3D vector.
Interactive function plotter
Graph up to three expressions, zoom the viewport and inspect values along the X axis.
Scientific notation converter
Express a number in standard and scientific notation.
