Orbital changes (Vis-viva) calculator

[Blaarkies]

Using the Vis-viva equation, we can calculate the delta-v required to move between various arbitrary orbits.

• [ ] A view that shows a body, and a craft
• [ ] Craft altitude is displayed
• Input form with relevant values
  • [ ] Altitude
  • [ ] Limited to body SOI
  • [ ] Velocity
  • [ ] Specify celestial body
  • [ ] Orbit line is drawn to match the input
  • [ ] Handling craft that are not at exact PE/AP
  • [ ] Record button stamps the current details
  • [ ] Changing these details now will show the difference in delta-v to achieve the new orbit
• [ ] In the end, the user will have a list of delta-v values describing the burns taken to reach the last orbit

This component is planned to be used in the pocket-calculators page
