Dimension Data Enables 97.5% improvement in Global Positioning

  • 12 July, 2005 10:24

<p>Sydney, 12 July 2005 – Dimension Data and the Victorian Department of Sustainability and Environment (DSE) have deployed a state wide, real-time networked Global Positioning System (GPS) correction service.</p>
<p>The service provides a 97.5 per cent improvement on traditional mobile GPS devices and will assist in providing accurate and secure location data to organisations requiring precise coordinates for operation. Such organisations include: precision agriculture companies; machine control organisations; emergency services; mining and construction companies.</p>
<p>The location-based services (LBS) positioning system was developed to provide GPS coordinates to within 50 centimetres of the location unit. Current GPS systems typically provide accuracy to within 20 meters of the actual location unit and are not suitable where precise coordinates are required.</p>
<p>Dimension Data worked with the Spatial Information Infrastructure (SII) division and the broader DSE organisation to plan, build and support a cost effective hybrid communications solution, now available to staff over the internet. Future plans include increasing this accuracy to within 20 millimetres of the unit.</p>
<p>The location-based positioning system uses a combination of DSE’s existing wide area network infrastructure together with carrier services and virtual private network technology to provide processed and accurate GPS data to users in the field in real-time.</p>
<p>“The biggest hurdle we faced with this deployment,” said James Millner, Location Based Services project manager, Department of Sustainability and Environment, “was the huge start-up costs usually associated with a project of this kind.”</p>
<p>“Dimension Data worked with us to make the most of our existing infrastructure and tailor a solution that didn’t require us to start completely from scratch. At the end of the day, we were presented with a proposal that met both our business and technical requirements and, as a result, we have a functional system that is easily updated when new communications services are brought on board.”</p>
<p>As a result, DSE staff can now use a GPS receiver and a suitably equipped mobile phone or similar communications device to fix their position virtually anywhere in Victoria. The key to the successful provision of corrected GPS readings is the speed at which the raw data can be sent and processed, so that the corrections can be provided to the user in real-time.</p>
<p>Gerard Florian, Chief Technology Officer for Dimension Data, said of the service, “The LBS has great potential for any services requiring location accuracy.</p>
<p>“In terms of government operations, it can be used to ensure vital infrastructure is not compromised when construction works are taking place. Similarly, the workers on these sites are aware of the precise location of submerged danger and safety is improved. On a broader scale, the service can even be used to measure geotechnical movements, such as in the snowfields, potentially averting another disaster like that in Thredbo in 1997.”</p>
<p>The system is based on a Cisco VPN concentrator allowing communication between those sites already on the DSE network and those outside the domain. Cisco VPN routers, clients and secure switches provide secure connectivity while a server cluster of seven Microsoft Windows XP servers maintains system functionality. Additional firewalls, VPN encryption, hardened operating systems, patch management, port scanning, intrusion detection and virus protection ensure data integrity and security in operations.</p>
