 note = {In the previous investigation it was shown that the determinant of a covariance matrix should 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 were normally distributed with zero means and equal variances. In the present investigation the determinant method is applied to cases where the observation errors contain not only random errors but also bias errors, provided that the values of these are mutually equal in each measuring instrument. The general properties of the optimum orientations are also shown. Furthermore the investigation is extended to include cases where some of the measuring instruments are out of order, as well as cases where there are misalignment errors in the configuration of the measuring instruments., 資料番号: NALTR1055000, レポート番号: NAL TR-1055},
