Millitron Posted August 27, 2011 Share Posted August 27, 2011 How do I know my satellites will stay in orbit? I can get a ship into a stable, pretty circular orbit at whatever altitude, and I understand that once you reach orbit, you stay in orbit (since orbital decay isn't modeled). What I mean is, when I decouple a satellite, how can I be sure that the decoupler's kick doesn't lower the satellite's speed too much and cause it to de-orbit?

A much easier way is to point horizontally at 90degrees to your line of travel and decouple like that. The magic of cosines will take care of the rest.

Millitron Posted August 28, 2011 Author Share Posted August 28, 2011 Not to mention thrusting only works if the satellite is not in-line with the engine. If the satellite IS in-line with the engine, the exhaust will fry it. Link to comment Share on other sites More sharing options...

Harder to land, though. Another possibility is radially mounting a couple of SFBs, parking the sat(s) on top of them, and using the SFBs for your deorbit burn, I suppose.

Millitron Posted August 28, 2011 Author Share Posted August 28, 2011 I would front-mount my satellites, but I can never seem to get them to fit properly inside any of the detachable nosecones. The nose cone always seems to fall partially off, and dangle to a side, pulling my whole rocket with it, if I have anything more than a command module and parachute under it.

Andras Posted September 9, 2011 Share Posted September 9, 2011 Brace the payload with struts.Like this, just add struts from the payload down. The decoupler is the LES blast cone.The new cargo shells by Capt Slug make it even easier. Link to comment Share on other sites More sharing options...
