Remote tech + mechjeb an 4 Satellite

[Harpi2600]

Hello I have a question I use mods and remote tech mechjeb and wonder guidance or advice on how to get mechjeb via satellite in geostationary orbit kerbinu so that the spacecraft was 90 degrees. I would have to put 4 Satellite. Thanks in advance for your advice

Actually you don't need to put them in geostationary orbit. All you need is to put 4-5 satellites in a high enough orbit so they can "see" each other, and make sure the space between them are fairly even. I did it and aimed for a 1000 km orbit.

The only really important thing is that the time it takes the satellites to make one revolution has to be quite accurate

Simplest way to get total coverage is to launch 3 satellites on one launch vehicle. Put the launch vehicle into an orbit with apoapsis at 2868.75km and a periapsis at 1225.5km. (The orbital period is the important thing here, it should be 4 hours.) Now in each of the next three orbits decouple one of the payload satellites. At apoapsis the satellite burns to circularize it's orbit at 2868.75km. (Again, it's the period that matters most. The orbital period should be 6 hours.) When you've circularized the orbits the satellites will be keosynchronous and evenly spaced at 120° giving you perfect coverage.

I hope that was clear and helpful.

If you don't want to/can't launch multiple satellites on the same vehicle, you can use the built-in rendezvous planner to align the satellites. You need to know the distance you want between each satellite (for four equally spaced satellites, orbit radius × sqrt(2)).

Launch your first satellite into the orbit you want. When launching your second satellite, set your first satellite as the target, and adjust the maneuver node so that you hit apoapsis at the height you want, and the "closest encounter" distance is the amount you calculated before. Then circularize at apoapsis as usual (like the others have said, the period needs to be as exact as you can make it). Repeat with the third and fourth satellites. With the fourth satellite you might want to try both the first and the third satellites as targets, just to make sure it's equally between them.

That should give you a more or less even formation, while letting KSP figure out the timing for you.

And how do I do that from 4 satellites?
