In addition to giving visual feed back from the LED's is it possible have real time positional data streaming on a laptop to simulate mission control?
My constraints on this project will be limited to skill, hours, and mostly money.
To address your other issues:you refer to attitude control as 6 degrees of freedom ... actually, it is 3 degrees of freedom.and then later, you ask if a 3-way accelerometer is sufficient? No, it isn't. To maintain the orientation ( attitude ) of the spacecraft, you need to detect its rotation, and for that you need a 3-axis gyroscopic sensor or equivalent 3-axis MEMS device, plus some means of accounting for the integration error ( drift ) resulting from the sensor readings. On earth the normal way to do this, is to use an accelerometer to deduce the reference direction of gravity, or alternatively a magnetic field sensor, which indicates the direction of the earths magnetic field. Usually both of these are required to prevent the attitude of the vehicle from drifting around some axis or another. You can also detect changes in the orientation of the craft if you have enough accurate accelerometers at the extremities of the craft to enable you to detect rotating motions, but that is unnecessarily difficult.
