This tool estimates an ideal constant-thrust maneuver. It does not select hardware or establish station readiness. The defaults are an illustrative ARLO mass case, not measured magnetic-nozzle specifications.
Equations and boundaries
vₑ = 9.80665 × Isp; mp = m₀[1−exp(−Δv/vₑ)]; impulse = mpvₑ; firing time = impulse/F; elapsed time = firing time/duty; P = Fvₑ/(2η). The power relation is an electric-engine kinetic-energy approximation, not chemical engine electrical demand.
The selected efficiency must include all propulsion electrical loads if the result is called total input. Non-jet power is not automatically all onboard radiator heat: exhaust and radiation can carry energy away. The tool excludes gravity and steering losses, drag during firing, reserves, propellant residuals, changing thrust, eclipse scheduling, structural flexibility and detailed trajectory integration.
