4 (float) SIGMA UP |
Shown in meters. |
|
4 (float) SEMI MAJOR AXIS |
The error ellipse in meters. |
|
4 (float) SEMI-MINOR AXIS |
The error ellipse in meters. |
|
4 (float) ORIENTATION |
ORIENTATION of the semi-major axis is in degrees from clockwise from True North. |
|
4 (float) UNIT VARIANCE |
Valid only for over-determined solutions. It should tend towards 1.0. A value less than 1.0 indicates that the a priori variances were too pessimistic. |
