1.11 Survey of 26mVLBI Antenna reference Point

1) In 1999, the survey of the reference
point of 26m VLBI antenna was
conducted through the same gindirect methodh applied for the survey of the
reference point of 36mVLBIantenna.

2) As displayed in Table 21, the results
gained from the calculation of the spherical center (reference point) by
applying the method of least squares to the eighteen (18) positioning
coordinates that were set separately by shifting the positions around the
spherical surface showed evidently that this reference point was appropriately
determined.
