  1. Antenna Tests at BEV Vienna 2002-2005 G. Stangl, H. Titz EUREF Vienna 2005

  2. Purpose • Equipment test (ca. 50 combinations receivers+antennas+radomes) • Stability of coordinates • Stability of environment (City, transmitters) EUREF Vienna 2005

  3. Test Network TUBO JOZE GOPE MOPI WIEN WIEB Star network WIEB-WIEN 6 m Others 20-500 km STPO PENC TRFB MTBG GRAZ EUREF Vienna 2005

  4. Equipment Types • Ashtech • Geotracer • JPS • Leica • Topcon • Trimble EUREF Vienna 2005

  5. Time Series • 2002 • DOY 219-226, 240-247, 271-285, 293-300, 320-327 • 2003 • DOY 063-078, 165-219, 237-241, 244-364 • 2004 • DOY 001-085, 117-131, 201-240 • Since 2005 WIEB in APOS network EUREF Vienna 2005

  6. Site WIEB with BEVA Radom (most used) EUREF Vienna 2005

  7. LEIAT504 Radom Tests (U) NONE BEVA GRAZ EUREF Vienna 2005

  8. ASH701045C_M BEVA – LEIAT504 NONE LEIAT504 NONE EUREF Vienna 2005

  9. TRM29659.00 – LEIAT504 NONE BEVA BEVA LEIAT504 NONE GRAZ NONE EUREF Vienna 2005

  10. TRM41249.00 NGS Corrections – LEIAT504 NONECorrect and Fake Antenna Heights PENC 2002 2003 +0.038 +0.025 +0.020 LEIAT504 NONE +0.015 NONE NONE BEVA EUREF Vienna 2005

  11. TRM41249.00 Different Corrections Antenna fake +0.020 LEIAT504 NONE LPT NGS EUREF Vienna 2005

  12. LEIAT502 – LEIAT504 NONE LEIAT502 LEIAT504 NONE EUREF Vienna 2005

  13. LEIAT502 Correction Sets Elevation cut-off 5/10/15/20 degrees Geo++ LEIAT504 GRAZ NGS Leica EUREF Vienna 2005

  14. 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
