[IMPORTANT RESEARCH - PLEASE HELP]. Figuring the average LKO altitude.

[SpaceSphereOfDeath]

Stations for me are at 150km, Science says are at 200km, and my parking orbit is at 75km

[Richy teh space man]

I've experimented quite a bit. I'm currently using a 80 x 80 km orbit for space plane support, my previous LKO space station was at around 250 x 250 km

[HeadHunter67]

When I launch to orbit, I tend to go for 75-80km, as Tw1 said that gives me some leeway for problems.

When I'm making a permanent orbit (for example, a station), I go for a nice tidy 100km orbit instead.

[rryy]

For LKO parking orbits, I tend to go somewhere in between 70 and 100 km.

[Valley]

A manned station at 70 to 80 km, than a fueling station around 100 to 140 km. Ships that park in orbit for any period of time will orbit between those ranges.

[Jason Cox]

I typically shoot for 75km for every launch. For manned vessels I then increase the orbit to 150km and for stations I push them up to 250km.

I keep my initial orbit so low as that means most of my spent stages are orbiting well below the orbit of my real missions.

[Epic DaVinci]

Everything is between 80 and 100 for me, that way i need less fuel or seperatrons for a de-orbit burn.

[Francesco]

75x75 km for parking orbits.

100+ km for space stations.

200+ km for stuff that has to "stay out of the way" (satellites etc.)

[Ralathon]

I dump practically everything in a 80km orbit. Stations, interplanetary transfer vehicles, spaceplanes. Everything.

This because you'll be moving the fastest in the lowest possible orbit, thus maximum usage of the Oberth effect. So it is mainly a matter of efficiency (and yes, I know it doesn't save me much).

I have it 10km higher than the absolute minimum so I have some leeway when I botch a rendezvous.

The only exception to this is my double duty Figaro GPS network and Remotetech relay constellation. Those are in a 3 hour period orbit.

[littlebattler]

I have a 72km and a 100 km orbit for my stuff. 72 km is for domestic spaceflight (to mun and minmus) and 100 km for interplanetary travel. SSTOs only go to the 72 km one, and crews are transported between the two stations using shuttles.

[Dravin]

I plan my lifters to take their rated payload to 100 km. However, if I'm heading directly to the Mun or Minmus I tend to hit 80 km and then transfer from there.

[Echostatic]

Station at about 100km, ships at about 80km.

[mrvile]

I generally circularize at 75km, I have a fuel depot at 150km and another arbitrary station at 200km.

[skykooler]

100km if I'm going somewhere; 300km for anything requiring docking, like space stations. The reason I put those higher up is that 300km is past the point where Kerbin stops rendering the atmosphere, so I get a much better framerate.

[El wonso]

125km because time warp. Station is at 220km just because wanted it a bit higher.

[NASI Director]

70Km-75Km orbit which I use to test stuff. Haven't done anything other than orbiting. Yet.

[Pixel of Life]

Just over 70km for testing new things, 80km for interplanetary missions and 100km for space stations.

[EvilotionCR2]

100x100KM is standart orbit for me.My station is at 150x150KM BTW.

Also,for me 70KM-200KM is LKO,200KM-400KM is MKO,and 400KM-end of the Kerbin SOI is HKO.

[lazarus1024]

It just depends. My typical orbit is probably around 120-150km. I generally put stations at around 250-300km to take advantage of 100x time warp. For interplanetary missions I generally assemble things around 150km. I generally consider anything at 300km or under as LKO. I rarely park anything at a higher orbit though, unless I am doing a really big mission with really low thrust to weight ratio. Then sometimes I'll have elipticals that can stretch out to 4, 5, 600+km with PE down around 90-100km. That said, those aren't really stable orbits so much as transfer orbits.

I'll get my ship from around 120-150km circular assembly orbit and drop PE to around 100km for an Oberth boost and then I'll start accelerating and pumping my AP higher on each successive orbit. So I might go from 100x130 to 100x180km on the first pass, then 100x250km on the second orbit, 100x400km the next orbit, 100x600km on the next, 100x1,000km the next orbit and probably breakaway from Kerbin SOI on the next orbit. That is usually only for really low thrust to weight ratio interplanetary ships. Most designs can achieve breakaway on the second orbit.

[Tripzter]

80-100 for launching new stuff, space station stays at 130km. After I complete it i'll lift it up higher in the 300s

[asmi]

My station is on 190x186x51.6 orbit, so I time my flights there either for direct ascent, or 1-2 orbit rendezvous. For flights bound elsewhere, I usually align launch window for direct departure burn without entering LKO orbit since in my Universe booster engines are not restartable.

[Guest]

80km standard parking orbit for interplanetary missions, 100km for testing new designs, 150km to 250km for LKO-only missions, 250km to 300km for Kerbin space stations.

[OopsThatNotWork]

80-100k for orbits prior to transfer burns. 250k-400k for stations.

[Jm419]

250k for my station, just because it's out of the render range of Kerbin. In the same vein, 175km is my typical parking orbit, but my SSTO orbit is usually as low as I can make it; like 73, 72k.

[RocketPilot573]

Well, with ships that have a high TwR, then I go with 70-75 Km orbits. But with other ships and Refueling Stations, I go for 150-350 Km.
