Abstract
Over the past few years, there has been substantial growth in multiple-reference-station networks used to overcome the limitations of standard real-time kinematic (RTK) systems. SydNET is a project to establish a permanent real-time GPS network in the Sydney basin area providing Network-RTK support to users in the area. SydNET is being developed by NSW Department of Lands in partnership with the School of Surveying & SIS at the University of New South Wales. This paper presents recent developments of the SydNET network. Preliminary test results will be presented which will show the network’s performance, achievable accuracy. It will outline the SydNET system, its operation, current status and vision of future development as a high precision positioning service infrastructure.
