1. EUREF Symposium Toledo 2003 ETRF-Austria 2002 EUREF-Campaign for the introduction of ETRS89 in AUSTRIA N. Höggerl, G. Stangl (BEV) E. Fragner, R. Weber (TUW)

2. EUREF Symposium Toledo 2003 Intentions Setting up a new national frame Based on GPS permanent stations Inclusion of non-governmental stations ETRS89 as a common system Free data access (post processing) confirmed Quality certificate (at least Class B) needed

3. EUREF Symposium Toledo 2003 Former net (2 permanent, 9 markers)

4. EUREF Symposium Toledo 2003 New net (10 permanent, 1 marker)

6. EUREF Symposium Toledo 2003 Data processing Bernese Software 4.2 Processing standards of EPN First solution constrained to GRAZ at epoch of measurements Official solution constrained to GRAZ, PENC, WTZR, ZIMM Transformation from ITRF2000 to ETRS89

7. EUREF Symposium Toledo 2003 Processing quality (7 sessions, 14 stations, 2 ACs)

10. EUREF Symposium Toledo 2003 Conclusions Change from markers to permanent stations necessary (users acceptance) ETRS89 for international compatibility Maintenance and permanent monitoring possible Same quality as EPN stations Accept proposal, please!
