| | | a space gyro is a gyro with three axis around which it can move (think of it as in pitch, roll and yaw, where I consider the pitch axis to be the spin axis)
as far as I know, space gyros aren't used in aircraft since they can take up any position
a tied gyro is in fact a horizontal referenced space gyro (the spin axis lies horizontally) with a button to prevent the gyro from toppling (ie roll) due to precession and is used in the directional indicator
after using the caging knob, as it is called, the tied gyro must be realligned (in case of the directional indicator with the heading indicated on the magnetic compass)
an earth gyro is as a tied gyro but vertically referenced (the spin axis pointing upwards) and having its spin axis tied to earth's gravity by means of a weight holding the spin axis pointing towards the center of the earth
the earth gyro is used in the artificial horizon
a rate gyro is a horizontal situated gyro and is only able to topple (and spin of course otherwise it wouldn't be a gyro)
the rate gyro is used to measure rate of turn around the third axis (yaw) and so it is used in a turn coördinator
I hope this helps and if there are any questions (or comments since this is my interpretation and I am still learning about gyros) please let me know
