ABSTRACT	In the previous investigation it was shown that the determinant of a covariance matrix shoud be recognized as a reasonable criterion for comparing the quality of observation systems, and the determinant criterion was applied to find the optimum observation systems for 2-dimensional vector sensing in cases where the observation errors were not correlated with each other and normally distributed with zero means and equal variances. In the present investigation it is explained that the vane-type flowdirection sensing systems are approximately equal to the 2-dimensional vector sensing systems mentioned above from the view-point of evaluation analysis for the observation systems. And the optimum orientations of the redundant vanetype systems are shown. Furthermore the general properties of the orientatins are clarified. Last, numerical experiments of error propagation are exercised to show how much influence the measurement and misalignment errors have on the final solutions
