In weightless space, there is a starting point. From this point to six directions (east-west, north-south, and up-down directions) six points of mass start motion simultaneously at the same speed. The state of six points of mass will show the state of non-accelerated frame. These will also be an indicator for all accelerated motion (for all not uniform linear motion).
If desired, the starting point can be made stationary on aether frame.
