Put in the first row of the first grid the digits 0 up to 8. Construct the second and the third row of the first grid by shifting the first row each time 3 places to the left.

The first three rows of the first grid consists of three 3x3 sub-squares. Construct row 4 up to 6 by swapping the sequence of the three columns in the three 3x3 sub-squares into 2-3-1 (instead of 1-2-3). Construct row 7 up to 9 by swapping the sequence of the three columns in the three 3x3 sub-squares into 3-1-2 (instead of 1-2-3).

The second grid is a reflection (rotated by a quarter) of the first grid. Take 1x digit from first grid +1 and add 9x digit from the same cell of the second grid.
1x digit +1 + 9x digit = panmagic 9x9 square

This 9x9 magic square is panmagic and 3x3 compact (but not symmetric).
You can use this method to construct magic squares of order is odd square (= 9, 25, 47, 81, ...).
This method gives not many possibilities (try it yourself).
