Abstract

Global Navigation Satellite Systems (GNSS) are commonly used in the surveying industry for establishing large geodetic networks where conventional terrestrial methods are considered insufficient. A primary example of this is long line control networks, typical of a pipeline project, rail corridor, or long line easement survey. The nature of these surveys often mean that they require careful pre-planning and increased resourcing, resulting large overhead costs to complete.

The aim of this research is to analyse the current adopted techniques for establishing long line control networks via GNSS methods, and to expand on these methods by determining new methods that would optimise the process. Recommendations can then be made regarding the establishment of long line networks via GNSS based on the desired time constraints and network quality in terms of uncertainty and network redundancy.

Testing the different configurations determined in the methods chapter of this dissertation revealed that configurations that adopt a conventional approach to GNSS static and quick static are likely to provide a higher quality network that is also cost effective. Furthermore, network configurations that adopted a less conventional approach lacked network quality, and were also less cost effective, despite the reduced number of observations required to complete the network.
