A short video demonstrating how Geoscience Australia through SouthPAN is bringing benefits to the maritime sector.

Geoscience Australia is developing technology, infrastructure and the tools needed through its Positioning Australia program to provide accurate, reliable and real-time positioning information across Australia and its maritime zones. This capability is being achieved through technology and infrastructure initiatives described in the flyer. This flyer was created for the International Mining and Resources Conference (IMARC) taking place on 31 Jan to 3 Feb 2022.

<div>FrontierSI has been engaged by Geoscience Australia (GA) to establish a series of case studies showcasing the benefits of Positioning Australia products and services through demonstrations of precise positioning capability. The Australian Institute of Marine Science (AIMS) was selected as the demonstration partner for this case study, contributing their extensive knowledge of current and future marine technologies and providing a suitably challenging environment for deployment of precise positioning solutions. This project investigates the available options for provision of precise global navigation satellite systems (GNSS) positioning at the AIMS Marine Operations Centre, and explores the suitability, benefits, and challenges of using Positioning Australia products including Ginan for this purpose.&nbsp;</div>

<div>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 11th and 17nd of September 2022. Campaign GPS data collected at 116 sites in seven 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 2.0 mm, 2.4 mm and 7.5 mm in north, east and up components of station position respectively.</div>

Ginan is Geoscience Australia’s Global Navigation Satellite System (GNSS) analysis centre software that delivers a real-time positioning correction service through an open-source software, and additional positioning products to enable precise point positioning for Australian industry and users.

We are pleased to announce the forthcoming release of Ginan version 3, a suite of open-source Global Navigation Satellite System (GNSS) software tools developed and maintained by Geoscience Australia in collaboration with industry and academia under the Positioning Australia program. Ginan serves as a precise point positioning (PPP) engine to produce real-time products that support high-precision positioning. Its versatility is demonstrated through its applicability to various geodetic and positioning activities, including computation of daily coordinate solutions, precise satellite orbit determination, computation of satellite clocks and biases, atmospheric modeling, and data quality assurance and quality control. These products effectively mitigate real-time errors associated with GNSS observations and are openly accessible as a centimeter-accurate correction service. The primary objectives of Ginan are: (1) showcase Australia's unique modelling and analytic systems for multi-GNSS real-time processing, delivering precise positioning products to both the Australian and international Positioning, Navigation, and Timing (PNT) community; (2) offer expert advice on navigation system performance over Australia; and (3) provide state-of-the-art GNSS analysis center software to universities and research organizations, thus fostering Australia's leadership in geospatial technology development. In this presentation, we will provide an overview of Ginan version 3, highlighting its new features, the current development status, and the strategic roadmap for its continued use as an operational service. We will provide examples of Ginan’s usefulness as a platform for research and innovation including its use as the processing engine for research into atmospheric anomalies from the Tonga volcano eruption through monitoring travelling ionospheric disturbances that could be used as early warning and tsunamigenic predictors for disaster risk and reduction; and observations of the Turkyia earthquake. The release of Ginan version 3 marks a significant advancement in GNSS data processing and positioning capabilities, contributing to the broader scientific community's understanding and utilization of geospatial technology.

<div>The aim of the Interferometric Synthetic Aperture Radar (InSAR) project is to develop an end-to-end, fully automated InSAR processing system that will take raw SAR data from any sensor and produce time-series maps of surface deformation/movement.</div><div>Surface deformation maps are important products to help define the national geodetic reference frame by augmenting the geodetic data obtained from sparse ground networks, in addition to identifying regions with elevated natural hazard risk.</div>

The Positioning Australia Program is delivering every day. Thousands of users from all around the country connect to our systems to access accurate and reliable data from a national network of continuously operating reference stations. A national capability cannot be achieved alone, it takes collaboration across all levels of government and industry. In this presentation Ryan and Amy will show how open data delivered through Positioning Australia is supporting the inland rail project and delivering better positioning services for farmers in South Australia. There have been many challenges to overcome in delivering this national capability. The speakers will discuss how GA has partnered with industry to facilitate access to land and build infrastructure across the nation during the COVID lockdowns and border closures. Finally, Ryan and Amy will share how we are working to continuously improve our offerings and access to our data and change the positioning landscape in Australia.
