We present angular dependent EPR measurements in ${\mathrm{NaV}}_{2}{\mathrm{O}}_{5}$ at $X$-band frequencies in the temperature range $4.2\ensuremath{\le}T\ensuremath{\le}670$ K. A detailed analysis in terms of the antisymmetric Dzyaloshinski-Moriya and the anisotropic exchange interactions yields the following scheme of charge order: On decreasing temperature a quarter-filled ladder with strong charge disproportions, existing for …
