I don't fully understand if it delivers exactly whats painted however, a small benefit over massive industries.
If it can really provide 100mm horizontal accuracy across much of the country it will improve performance and reduce costs.
Presently many who use RTK GPS systems for agriculture, fisheries, mining or any natural resource managers would be in for big savings and opportunities.
Even construction would benefit as they use plenty of differential systems for earthworks. A heap of time, effort and expertise spent setting up and managing GPS networks so equipment and others can operate accurately. At a minimum SBAS should make this easier.
There is a CORSNET operating currently but only effective nearby base setups and within high speed data mobile services coverage

........major productivity improvements for agriculture, mining, engineering, logistics, transportation and location-based services (Figure 2). The gross benefits of precise positioning to the agriculture, mining and construction sectors alone in 2008 were estimated to be between $800 million and $1.5 billion per annum (Allen Consulting, 2008).
