Background

At the UNSW Australian Centre for Space Engineering Research and the School of Surveying and Geospatial Engineering we are interested in positioning for all sorts of applications; traditionally to locate and re-locate historical land boundaries, for large engineering infrastructure development, to control mining operations, for undersea floor location and oil and gas exploration. In the last 20 years, satellite positioning has revolutionised the way surveyors and spatial information professionals provide position.

The Global Positioning System (GPS), operated by the US Department of Defense, was the first, and remains the most widely used, positioning service. Its initial design was to provide instantaneous positions to civilians to a few tens of metres accuracy, however researchers have devised a myriad of techniques and devices that can now squeeze positions to cm accuracy in next to no time at all. And now the landscape of satellite positioning is taking on a whole new face.

The Russian system, called GLONASS, has an almost complete constellation, for the first time since the mid-90s. The Europeans are set to launch their own constellation of positioning satellites called Galileo and the Chinese are beginning to launch satellites for a regional positioning system over China, which will evolve into a global system known as Compass. The Japanese and Indians are also planning to develop regional positioning services too. We don't talk about only GPS anymore, now we talk about GNSS - global navigation satellite systems, and RNSS - regional navigation satellite systems. So how can we exploit all these new signals from space to improve positioning even further?
