Ginan Achieves A Significant Milestone

FrontierSI is pleased that our long term collaboration on the Analysis Centre Software (ACS) project has reached a significant milestone, with the public release of an alpha version of the software and the renaming of ACS to Ginan by  Geoscience Australia.

Ginan is named after the fifth-brightest star in the Southern Cross. Geoscience Australia’s National Positioning Infrastructure Branch Head Dr Martine Woolf said that the software name is a gift from the Wardaman people of the Northern Territory. Ginan is a Wardaman word and the star is an important star in Wardaman culture as it represents a red dilly-bag full of songs and knowledge.

The Ginan software is available under an open-source licence from Geoscience Australia’s Ginan GitHub website [1]. Ginan 1.0 is on track for beta release in February 2022 and production release of Ginan 1.0 is scheduled for June 2022.

The Precise Orbit Determination (POD) component of Ginan was a core deliverable of the CRCSI (now FrontierSI) positioning program which in June 2018 delivered version 1.0 of that software. Since then, the Ginan team has been working to develop the Parameter Estimation Algorithm (PEA) component.

The Ginan Alpha release sees PEA and POD working together as an integrated unit, allowing users to utilise the open-source software to provide real-time corrections to positioning data from Global Navigation Satellite System (GNSS) constellations. Ginan can facilitate 3 to 5 centimetre location accuracy for industry users with suitable GNSS receivers and internet coverage. This will enable industry to value-add and provide reliable centimetre positioning to their customers.

To find out more Geoscience Australia recently presented a Ginan webinar which is available on the Geoscience Australia YouTube channel [2].

Impact of Geoscience Australia’s Positioning Australia program

Geoscience Australia is the national focal point for positioning coordination and is part of a global network delivering positioning capability through ground station infrastructure and satellite technology.

Through its Positioning Australia program, Geoscience Australia provides accurate, reliable and real-time positioning data across Australia and its maritime zones.

The program enables government, industry and the community to draw on Geoscience Australia’s trusted positioning data to support innovation, improve workplace and community safety, increase productivity and accelerate economic growth for our nation.

In time, Positioning Australia will improve positioning accuracy from 5 to 10 metres, to 3 to 5 centimetres in areas with mobile phone and internet coverage that can deliver the Geoscience Australia position correction data.

Ginan is an essential component of Geoscience Australia’s National Positioning Infrastructure Capability (NPIC) initiative and supports the vision of instantaneous GNSS positioning, anywhere, anytime, with the highest possible accuracy and the highest possible integrity. It will help deliver accurate, reliable and instantaneous positioning across Australia and its maritime zones and lower the barriers to accessing advanced high precision positioning technology in Australia. Examples of how Ginan’s data could be used include reducing fertiliser and chemical spray waste in agriculture. It could also improve the operational efficiency of large mine sites through greater use of automation. Our precise location data will inform us of near real-time atmospheric conditions, which is already being used by the Bureau of Meteorology to assist with their weather predictions. It will also enable a greater understanding of movements in the Earth’s crust and provide insight into earthquakes, sea level changes and the atmosphere. Ginan will enable Australian industry to progress and allow for innovation across all sectors such as agriculture, transport, emergency management, mining, engineering and logistics.
