Altitude changes when time warp is used

[geschnetz]

Hello to the KSP community!

I had done an intense search in this forum, but i can't find anything about my problem. So i hope i don't miss a post where this has been already discused. If so, i have to apologize in advance.

So here we go: I wanted to install a mircowave power network. So i tried to put satellites in the exact same orbit. In this case 300,000m above kerbin. But if it comes to the exact meter i discovered that if i start the time warp my altitude jumps and changes. In the normal time mode everything is stable. It is impossible to get an exact orbit because of this problem. At first i thought it is because some parts clips into each other, so i have build a satellite where no parts are clipping. Nothing changes. But this anomalie happens not everytime. For example, the relays dont jump around. There it was no problem to put 4 of them into the same orbit. What do i wrong?

The vehicle contains of course parts of the interstellar extended mod. Game version is 1.1.3.

Does anyone knows something about that?

Hey, the altitude is not that important, yes ofcourse a bit, but you can't circle endless till you have done a ton correction burns. I suggest you to install KER, if you didn't do it already.  

Match the orbital period. When matching them all to the same time, the probes won't drift apart. To see what for orbital period you need for 300km you can use my calculator in my signature. Or just deploy one craft and take it's time to match the rest. It nearly impossible to match your orbits through altitude... and you orbits don't need to be perfectly sirculair, as long as they aren't totally eggshaped it's ok.

 

It happens to me too, the altitude changes during warp. so most of the time I burn to the desired Ap, from my Ap I burn to the desired orbital time and from there I don't touch my craft anymore, ever.

Thank you for the fast reply!

Of course i have installed the KER Mod. I think without it, it is a real challenge!

Ok, i see what you mean. I have tried it and i think it is a stable orbit. At least the orbital period and the orbital velocity are the same. So i hope that they will stay in that position.

Thank you very much for this workaround! But i would be very happy to solve the problem or to know how to avoid this bug...

btw: With an electrical engine lowered to 0,5% of thrust it is really easy to get an orbit which is to the exact meter identical to another vehicles orbit. With 4 relay satellites in a 2,500.00 km orbit, it was a 1h work. Nothing difficult or impossible (if this annoying bug doesn't appear).

Yes, indeed.. but I don't know anything about the status of the bug atm.

I normaly use RCS for the job, it's cheaper. Indeed, setting it to 0.5% results to big precision. Especially with KER installed, 0,000 seconds percise.

 

Btw, welcome to the forums!
