Positioning Regional Victoria (PRV) Project
|In its May 2008 budget the Victorian Government committed $6.9 million in funding to extend Vicmap Position – GPSnet™, a high accuracy Networked Real-Time Kinematic (NRTK) positioning service, state-wide in a five (5) stage prioritised rollout from 2008 through to 2011.
The Positioning Regional Victoria project was allocated $4.9 million to augment Victoria’s Vicmap Position - GPSnet™ Continuously Operating Reference Stations (CORS) network. The successful completion of this project provides high accuracy positioning and navigation corrections for Global Navigation Satellite System (GNSS) applications state-wide.
The remaining $2 million is being invested by the Department of Environment and Primary Industries (DEPI) to install a further estimated 11 GNSS CORS (including 8 AuScope GNSS CORS sites) and upgrade the Vicmap Position - GPSnet™ backend infrastructure.
On completion of the entire program, Vicmap Position – GPSnet™ will consist of approximately 100 GNSS CORS providing a nominal state-wide real-time horizontal accuracy of ±2cm.
Project componentsThe project is being managed as a series of sub-projects:
- Industry economic benefits analysis of high accuracy positioning
- Expansion and densification of the Vicmap Position - GPSnet™ CORS infrastructure (estimated 57 new CORS installations statewide)
- Vicmap Position – GPSnet™ web site redevelopment
- Vicmap Position – GPSnet™ automated tracking and billing system
- Marketing and promotion of Vicmap Position - GPSnet™
Benefits of the projectThe expansion of the Vicmap Position – GPSnet™ network will help drive business productivity and competitiveness, and improve environmental and social outcomes.
The project offers a strategic and rational alternative to the proliferation of ad-hoc and typically single arrays of individual overlapping short range base stations.
The PRV Project will deliver the following state-wide benefits:
- Reducing cost of entry to high precision satellite positioning by eliminating the need for a user to acquire, manage and operate their own dedicated GNSS base station
- Virtually distortion free positioning and navigation at a nominal horizontal accuracy of ±2cm
- Support for legal traceability of position
- Synchronisation to the national spatial referencing system, enabling user positioning outcomes in strict compliance with the Geocentric Datum of Australia 1994 (GDA94)
- Universal nonproprietary data formats, increasing user choice of equipment and flexibility
- Remote control and monitoring of all network CORS for data quality and impact by space weather and other external effects.
