KSP Orbits

A 2D Kerbal Space Program simulator that is useful for calculating continuous burns and planet interceptions in KSP.

FEATURES

• Simulates orbits of Kerbin, Duna and their respective moons
• Allows for a ship to be “launched” in a circular orbit around a body at a prescribed altitude, or placed in space by specifiying orbital parameters
• “Ship” can take conditional instructions for when to change heading or throttle
• Headings can either be “absolute” (using the x/y coordinate system used by the canvas, relative to the parent body) or “relative” (with 0 being prograde and -PI being retrograde)
• Renders elliptical orbits

TODO

• Track fuel consumption
• Fix issue with rendering conic sections when zoomed too far into a large ellipse
  • Most likely caused by a floating point issue
  • Possible fix: break ellipse into more segments when zoomed in by splitting the bezier curve http://pomax.github.io/bezierinfo/#splitting
• Add parabolic and hyperbolic orbits to conic renderer
• Add rest of planets and moons
• Add panning and zooming directly with mouse
• Automatically decrease step size for objects being calculated in cartesian coordinates when the throttle is set to 0 and the energy of the orbit changes too much
