January 2015 saw – for the first time – Australia achieve 5cm real-time positioning accuracy during a trial of Japan's Quasi Zenith Satellite System (QZSS) in rice growing operations located near Jerilderie (NSW).
The CRCSI partnered with the Japan's space agency JAXA, along with 13 Japanese and Australian companies and research agencies to test the concept of centimetre real-time positioning accuracy for precision agriculture.
Partners in this research included: Hitachi Zosen Corporation, Hitachi Ltd, Hitachi Solutions, Yanmar Co Ltd, JAXA, Hokkaido University, Hitachi Australia Pty Ltd, University of New England, RMIT University, University of New South Wales, Rice Research Australia, SmartNet Australia, CR Kennedy Pty Ltd, and Precision Agriculture.
More recently, in December 2016, a second trial was conducted in the sugar growing region of Mackay (QLD). Additional partners from Farmacist and the Queensland Department of Natural Resource Management provided further expertise.
The Mackay trial sought to better understand the varying ionospheric and tropospheric conditions that impact the GNSS signals along with the topography of sugar cane fields.
The outcomes of this research has been the delivery of more reliable signal and transmission corrections when compared to the Jerilderie trials.
The economic impacts of this real-time positioning capability for Australia through productivity improvements and better resource efficiency are estimated at around $13.7B by 2020.
