Geospatial Observatory

Nodes - Lead nodes at Geoscience Australia and the Australian National University

Contacts

Gary Johnston - Geoscience Australia

EIF funding - A$6.4 million

Project duration - July 2011 to December 2014

Summary

Geodetic observations can provide the spatial and temporal estimates of large-scale surface deformation across the Australian continent. Combinations of multiple techniques (e.g. GNSS, InSAR, gravity) can yield deformation estimates with mm accuracy at the full range of spatial densities from continental to local. Underpinning this is the dependency on the accuracy of the coordinate reference system.

Infrastructure

• Deployable GNSS Instrumentation Pool
  
  • for episodic campaigns nationally/regionally. This pool (100 GNSS units) would be administered by a national facility such as ANSIR.
• Geodetic Antenna Calibration Infrastructure
  
  • Robotic Calibration system
  • Precision total station, precise targets and observing enclosure
  • Temperature sensors and loggers
• Design and installation of new geodetic monument arrays
  
  • Design, construction and installation of GNSS monuments
  • Design, construction and installation of radar reflectors
  • 4 CORS GNNSS stations
• Remote Sensing Data Portal

All designed for improved precision and accuracy for geospatial science.
