Geoscience Australia (GA) plays a coordinating role across government to provide accurate positioning information and data, and maintains a national network of Global Navigation Satellite System (GNSS) ground stations which forms part of a global observatory network.
Typically positioning systems allow for positioning to within 5-10 metre accuracy. GA is developing the capability to provide better than 5 cm accuracy positioning information to the public, at a national scale.
Precise positioning at this level opens a range of new and innovative applications, including major productivity improvements for agriculture, mining, engineering, logistics, transportation and location-based services.
In order to overcome the current gaps in coverage from mobile and radio communications, GA is deploying a test project of a Satellite-Based Augmentation System (SBAS). This will ensure that accurate positioning information can be received anytime and anywhere within Australia and New Zealand.
Vision for the future:
– Transition to real-time operations
– Transition from static to kinematic applications support
– Transition from science to industrial and environmental applications
– Scaling from 1,000 users to 100,000+ users
To scale for future needs, GA has migrated large parts of its data centre into the cloud (Amazon Web Services), and is currently in the process of modernising the infrastructure for data delivery. Jonathan will cover the challenges and successes in rolling out this infrastructure.
Jonathan is a software developer at Geoscience Australia (GA), working in a team together with software developers and geodesists, building network infrastructure to provide centimetre-level positioning capability at a national scale. He studied software development at Australian National University, and he joined the Geodesy team at GA in March.
