I'm building a comms network as early stages of the game. The idea is to put three unmanned probes on the same orbit around Kerbin at relatively same distance from each other. This is made to ensure signal from another side of planet when KSP center is the only transmitting point on surface of Kerbin.

Problem I'm getting is kind of trivial, but not very easy to solve. (for me at least). Then I put second satellite in orbit, I noted that the first satellite is catching up. This, I believe, is not a trick of perspective, but slight misalignment in orbits.

Now, my network probes are real barebones. All they have is couple of solar panels, antennas and batteries. Engine is ditched after satellite is placed, so I can't move them freely yet. (I'm going to build a space tug and rethink satellite design later) This means initial placement must be perfect in order to ensure signal at all times.

I guess I could throw in more satellites, but what could guarantee they wouldn't buch up on the other side of the planet the day I desperately need them?

So I'm asking if anyone could suggest mods for better orbital trajectory planning. I'm not doing that by hand - it would exced my effort limit.

Запусти четыре спутника, вместо трех. Так можно легко визуально ориентироваться. Для контроля орбит советую мод KER - следи чтобы все спутники имели одинаковые АП, ПЕ и инклинацию. Причем советую иметь ПЕ чуть меньше АП, чтобы не получить баг с само-растущей орбитой - но у всех спутников эта пара должна быть одинаковой.

Для размещения впомни простое правило - все что ближе к планете летит быстрее, все что дальше медленее.

Grab the mod "Kerbal Engineer Redux". You can customize it to show whatever you want, but the readout I love is the Orbital Period readout.
Just put your sats in a parking orbit, raise the first one, note down its orbital period, then go to the others and match it as closely as you can.
I usually get them within a few hundredth of a second of eachother (0.1 throttle limit and quick reflexes) which means I've not had to touch their orbits in... well since I placed them there.

Edit: Important to note that their orbits don't have to be in the exact same place. As long as their orbital periods are similar, they'll keep equal spacing.
