A local tie survey was conducted at the Mount Stromlo Satellite Laser Ranging (SLR) observatory, in Canberra in August of 2006. The aim of the survey was to precisely measure the local terrestrial connections between the space-based geodetic observing systems co-located at the observatory, which include GPS, GLONASS, SLR and DORIS. In particular, this report documents the indirect measurement of the SLR invariant reference point. Geoscience Australia has routinely performed classical terrestrial surveys at Mount Stromlo, including surveys in 1999, 2002 and 2003 (post-fire). A high precision survey was conducted between the survey pillars surrounding the SLR observatory. These survey pillars were monitored to ensure their stability as part of a consistent, stable terrestrial network from which local tie connections were made to the SLR and other observing systems. The relationship between points of interest included the millimetre level accurate connections and their associated variance covariance matrix. {"type": "Polygon", "coordinates": [[[149.007, -35.318], [149.012, -35.318], [149.012, -35.314], [149.007, -35.314], [149.007, -35.318]]]} 149.007 149.012 -35.318 -35.314 AU-ACT Earth Sciences GA Publication Published_External Record geodesy Related Product documentDigital ftp://ftp.ga.gov.au/geodesy-outgoing/local_tie/sinex/ HTML Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
