Ok new year,
time to rehash old ideas and see if any new wisdom or technology has solved this yet or not.
Last we left our heros were talking about how to make sure our rockets where straight up and not off course before firing the sustainer.
Back in 2005 several mentioned tilt switches and many recanted how if you fall off the clift it still can't tell you are really going down or up.
2006 had many talk of the MAD and also others talk about MAD issues.
2007 had many point to the new 3-5, and 6 axis accelerometer
Bob mentioned that a 3-axis accelerometer and a compass could be used to tell your attitude. Robert mentioned you should be able to do it with 6-axis somehow.
Many pointed out the new tilt compensated compass, but again it was pointed out anything with tilt-compensataion will work for a robot or sub, but not a rocket in free space.
It's time to bring up our friends at SparkFun again with two items that have me thinking today:
3-Axis Magnetometer

IMU 6 Degrees of Freedom

Pros?
Cons?
Lets Discuss
