The integrity and strengths of multi-technique terrestrial reference frames such as ITRF2005 depend on the precisely measured and expressed local tie connections between space geodetic observing systems at co-located observatories. A local tie survey was conducted at the Yarragadee (Moblas 5) Satellite Laser Ranging (SLR) observatory, on the Yatharagga property in Western Australia, in May/June of 2007. 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 the Moblas 5 SLR observatory, including surveys in 1992, 1999, 2001 and 2003. A precision survey was conducted between the permanent survey monuments surrounding the SLR observatory. These survey marks 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.
