EUREF Vienna 2005 TRM NGS Corrections – LEIAT504 NONE Correct and Fake Antenna Heights NONE LEIAT504 NONE NONE BEVA PENC
EUREF Vienna 2005 TRM Different Corrections LEIAT504 NONE NGS LPT Antenna fake
EUREF Vienna 2005 LEIAT502 – LEIAT504 NONE LEIAT504 NONE LEIAT502
EUREF Vienna 2005 LEIAT502 Correction Sets Elevation cut-off 5/10/15/20 degrees NGS Leica Geo++ LEIAT504 GRAZ
EUREF Vienna 2005 Conclusions/Recommendations LEIAT502: not usable for precise permanent stations – appropriate correction for Bernese Software still missing, large elevation dependency probably caused by antenna design Trimble Zephyr: Replace NGS corrections by LPT corrections by international convention, until then a faked antenna height would be best to avoid height jumps in the time series PENC: Not usable anymore for Austrian EUREF representation (distortion by height jump after antenna exchange)
EUREF Vienna 2005 Thank you for attention!
