Abstract
<div>The integrity and strength of multi-technique terrestrial reference frames, such as realisations of the International Terrestrial Reference Frame (ITRF), depend on the precisely measured and expressed local-tie connections between space geodetic observing systems at co-located observatories. Australia has several observatories which together host the full variety of space geodetic observation techniques, including Global Navigation Satellites Systems (GNSS), Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) beacons.</div><div><br></div><div>This report documents the technical aspects of the local tie survey completed at the Mount Stromlo observatory, in Canberra in 2014. 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 3 International GNSS Service (IGS) stations, SLR and DORIS infrastructure. 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.</div><div><br></div>

Purpose
This report provides a continuation of the local tie connection data set obtained at the site, to provide an updated value of the local tie vectors for use by the international geodetic community and determination of the international terrestrial reference frame (ITRF), and to allow comparison to previous solutions so to monitor deformation in the local system.

Lineage
<div>This document is a report about the terrestrial survey completed at the site in this year. It is a continuation of a set of results from similar works completed at the site in previous years. The current report references the results of the previous work, but for complete workings of previous surveys, refer to the relevant report of that dataset.</div>
