Update for new versions? #25

Open ZatriX opened 6 years ago

ZatriX commented 6 years ago

I don't know if something has changed in Kerbal universe or it's a bug somewhere in the code, but not all transfer windows are accurate.

Example: Kerbin to Moho, year 2. It calculates optimal launch to day 87, however Moho's orbital position is way off, instead of -215 degrees it's like 5, therefore no encounter (see screens).

required actual calculated

I have not kept up with the latest versions, but I would be surprised if anything has changed that would affect the launch window planner. Make sure you have the correct date format selected (Earth time vs Kerbin time). Also, Moho is the trickiest planet to transfer to. You must be very precise with your transfer and even then it will usually require a mid-course correction. Because Moho's orbit is fast and elliptical, the phase angle varies dramatically depending on where it and Kerbin are in their orbits.
