# Helper: SDOC - Satellite Deploy Orbit Calculator

## Question

Hi together

I love to deploy multiple satellites on the same orbit. To be sure that they have all the same separation to each other I have to calculate the orbital time for my parking orbit.

The most known calculation is to put 3 satellites in a synchronious orbit around Kerbin:

(synchronious orbit period / amount of satellites) * (amount of satellites - 1)

1d = 6h = synchronious orbit period

(6h / 3) * (3-1) = 4h

So park your vessel in a 4h orbit with the AP on the edge of the synchronious orbit. Deploy every pass on the AP one satellite. When done correct you have a nice triangle around Kerbin.

So i love to do that on other bodies and in other (non-synchronious) orbits. So I had to do the math all the time.

Now I've made a little calculator and will make this accessable for all of the community which needs this.  So feel free to use it!

Its very simple and doen't check if your orbital period goes into a collision with the celestial body. So check first :).

Edit: Here an example: I cheated my craft with 4 satellites into a random eeloo orbit and calculated the values:

Nice tool, could use it; my current comm net is a complete mess
