The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). This document describes the data analysis of the APRGP GPS campaign undertaken between the 16th and 22nd of September 2018. Campaign GPS data collected at 101 sites in ten countries across the Asia Pacific region were processed using version 5.2 of the Bernese GNSS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2014 reference frame by adopting IGS14 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products. The average of the root mean square repeatability of the station coordinates for the campaign was 1.8 mm, 1.6 mm and 5.4 mm in north, east and up components of station position respectively.

The AMSIS Distance To tool calculates the distance to a selected marine feature. The output is the distance to the nearest feature from the given location.

This collection includes Global Navigation Satellite System (GNSS) observations from short-term occupations at multiple locations across Australia and its external territories, including the Australian Antarctic Territory. <b>Value: </b> The datasets within this collection are available to support a myriad of scientific applications, including research into the crustal deformation of the Australian continent. <b>Scope: </b> Data from selected areas of interest across Australia and its external territories, including the Australian Antarctic Territory. Over time there has been a focus on areas with increased risk of seismic activity or areas with observed natural or anthropogenic deformation. <b>Access: </b> The datasets within this collection are currently stored offline, to access please send a request to gnss@ga.gov.au

The Print Service provides PDF map prints via an online interface. This service prints detailed PDF maps, including scale bar and marginalia.

The Criteria Assessment tool takes the input path or area created by the user and the input variables chosen to generate a heat map surface, KML surface, KMZ surface and PDF Report. This service is specifically for use within the Carbon Capture and Storage application.

<div>The Pacific Islands Applied Geoscience Commission (SOPAC) requested Geoscience Australia to compute International Terrestrial Reference Frame (ITRF) coordinates for 18 survey sites on islands in the northern Fiji archipelago from continuous geodetic GPS measurements observed from 8th July to 5th August 2008 inclusive. The GPS data was processed using version 5.0 of the Bernese GPS Software in a regional network together with selected IGS sites. The GPS solution was constrained to the ITRF2005 reference frame through adopting IGS05 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products.</div><div>These coordinates provide the coordinate reference frame to be used to define Fiji’s claim to extended continental shelf under the provisions of Article 76 of the United Nations Convention on the Law of the Sea.</div><div><br></div>

Since its launch in 2001, Geoscience Australia's online positioning service (AUSPOS) has continued to be a widely used tool for the online processing of geodetic GPS data for surveying, mapping, geodetic, geophysical, hydrographical, military and other applications. On 20 March 2011, Geoscience Australia released an updated version of the service, AUSPOS2. This update implements recent advances in analysis software and strategies, the reference frame ITRF2008, AusGeoid09 and the latest transformation parameters between ITRF2008 and GDA94. AUSPOS2 now delivers ITRF2008 coordinates with an uncertainty less than 10 millimetres to users within 3-5 minutes while continuing to provide Australian users access to GDA94 coordinates and derived AHD heights to the highest achievable accuracy. This talk will overview the AUSPOS2 system and how users can best exploit this free service.

The national measurement system in Australia ensures a basis for legally traceable, consistent and internationally recognised measurements. With the growing societal dependency on GPS, the need for the legal traceability of GPS positions with respect to the Australian Datum - the Geocentric Datum of Australia 1994 (GDA94) -- has become increasingly apparent. In the interest of ensuring consistency of positions derived from private and government Continuously Operating Reference Stations (CORS),Geoscience Australia maintains an appointment as a legal metrology authority in accordance with the National Measurement Act 1960 and provides legally traceable positions. This presentation will overview Geoscience Australia's approach to the legal traceability of GPS positions, the process of legal certification including: (1) the basic requirements for requesting certification; (2) quality standards and the quality management system of the position verification processes. The structured maintenance and continual improvement program for the verifying laboratory will also be introduced.
