Abstract

Satellite navigation has been available in the aviation and maritime worlds since GPS system was built in the 1970's and users were able to navigate anywhere in the world with unheard-of accuracy of less than a hundred meters. Since then other systems have emerged and a new term, Global Navigation Satellite System was born to generalise the concept.

Now that there are four different GNSS systems in a stage of development that includes satellites in orbit, it is prudent to ask the question: which GNSS system best suits the Australian user? This project took the task of finding information about all four GNSS systems that would enable an evaluation of performance of each system.

The project devised an evaluation framework for ranking the benefits and a methodology of assessing identified indicators of such suitability against that framework. As a result, differences were found, impacts of those differences were assessed and results tabulated in a matrix of ranking.

With limited resources and scope, the results can be seen as discussion enhancing rather than authoritative points of view and others may have other ideas of where the emphasis should lie.

The project report nevertheless covers a wide range of topics that would be included in any assessment into the needs of an Australian user.
