Applications
Over the next decade considerable growth is expected in the use of GNSS as increased positioning accuracy and system reliability provide cost savings and other benefits for a wide range of economic and social activities that rely on location. There are many applications in Queensland already using combined receivers that track GPS and GLONASS satellites.
Location-based services are relevant to the following industries:
- agriculture
- building and construction
- emergency management
- search and rescue
- transportation
- tourism and recreation
- telecommunications.
The provision of these services will create both direct and indirect business and employment opportunities. The delivery of Galileo, the modernisation of GPS and the revitalisation of GLONASS will be key elements in fuelling growth in both infrastructure provision and location related business services.
The benefits of more satellites and improved satellites signal design include:
- continuity—users accessing data from multiple satellite systems can continue to operate if one of the systems fails
- accuracy—the potential for sub-metre positioning in a standard handset
- efficiency—centimetre accuracy with shorter initialisation times
- availability—more than 60 navigation satellites orbiting with approximately 10 available to users working in urban canyons, under tree canopies or in open cut mines
- reliability—more reliable signal tracking, also designed for Safety-of-Life applications, such as aviation, that require extremely high performance levels.
