    This is one of the biggest gotchas. My personal strat is to drop the atmo probe off in low (polar) orbit, then boost up the AP of the relay on the Kerbin-facing side of the planet. This way you just wait for a time when both vessels are coming from round the back of the planet and start the descent. Should have plenty of time with the comms relay accessible.

    Bit harder for Jool due to it's scale and the fuel cost of changing your orbit. You may wish to establish the relay in high orbit as a separate vessel entirely.

    IIRC, didn't Galileo release the probe before it even entered Jupiter orbit?

    This is it. Assign the deploy angle to a KAL-1000, and then assign that to the throttle. I use the same one that controls engine torque and/or RPM, and the blade pitch.

    The torque of the flaps will change as airspeed changes, though. How do I account for that?

    Is there a way to make the trim proportional to the throttle, since changing the torque and/or propeller angle changes the torque on the airframe?

    I have an idea. I can have trim flaps deploy when I turn the engine on, and have deploy angle proportional to throttle.

    Then deploy some solar panels/RTGs to power them; remember solar panels don’t work when it’s dark… There’s also a mod called Deployable Batteries which, surprise, adds deployable batteries that can power stuff at night when your solar panels are off, though you’d need even more solar panels to recharge the batteries during the day.

    Is there a specific order in which I need to deploy things so they connect?

  5. I'm trying to write a software-defined IMU program in kOS using the stock accelerometer sensor. It measures acceleration, integrates to find velocity, and integrates again to find position. Unfortunately, the coordinate system that kOS is using makes no sense. How do I make my own ship-centered coordinate system with X pointing east, Y pointing radially up, and Z pointing north? And, since the origin is at the center of the ship, will that make all accelerations in that reference frame zero since it can't accelerate relative to itself?

  6. Is there a way to mathematically simulate many, many gravity turn profiles to find an optimal one for a given rocket? I want to find a way to automate launches in kOS such that it adjusts the flight profile for the specific vehicle.

    Given a thrust to weight ratio, I want to find the optimal vertical speed at which I should pitch over by 5 degrees.

  7. How do I make a geosynchronous constellation where the orbits are elliptical and the apoapses form the vertices of a tetrahedron?

     

    EDIT: The tetrahedron should just rotate in place, with none of the vertices moving relative to each other.
