Contents
! Recent activities of AUT ! IVS, 30m antenna,
SKA, Geodetic experiments
! Contribution of Warkworth ! New Zealand geodesy ! GGOS project
! Improving the estimation of the ocean tide loading displacement at Warkworth
Recent activities of AUT 1/4 ! Ww 12m radio telescope
! Launched on October, 2008
! Participate in the global IVS sessions regularly since the beginning of 2011
! GGOS aims: 1) accuracy of < 1 mm for position 2) accuracy of < 0.1 mm/yr for velocity
! by using and integrating advanced geodetic observing techniques

has capability to became a core site
Important contribution to geometrical distribution
Warkworth
“Call for Participation”
Ww contribute to NZ geodesy Ww become a core site
! There are no Absolute Gravimeters or Superconducting Gravimeters
! Observation ! Christchurch ! Southern Alps
Gravity measurement in NZ

only South Island the gravity value should change
Absolute gravity base station must be in North Island - monitoring : volcano, uplift, etc. - continuous measurement - co-located multiple geodetic techniques
