Hi,

for a first check, I transform lat/lon/height to X/Y/Z (WGS84). The corresponding coordinates read:

CIQE 609086.575860679 -6246622.90882520 1135491.70093521
PUNT 565870.301787418 -6256745.19933001 1098060.79280774
RIDC 611248.433670597 -6254807.29657424 1091707.74690573
CASA 653126.771933286 -6250773.77345104 1090658.12307496

The distances between the new point and the GNSS stations are given by

62982.6821515789
87773.2819741715
42085.2258472698 ***

The corresponding baseline lengths are

62985.4455998656
87777.3345821874
1884.15173177905 ***

There are large discrepancies between the distances derived from coordinates and the corresponding baseline lengths. Can you check your input quantities?
