Many applications of Global Navigation Satellite System (GNSS) technology, such as surveying, mapping and precise navigation, require real-time positioning accuracies to centimetre levels. To support these applications, many countries are establishing dense networks of continuously operating reference stations, positioned typically less than 40 km apart. However, for Australia with its large and sparsely populated regions, these dense networks cannot be justified economically. Our project will investigate appropriate enhancement of sparse networks to maintain the same level of accuracy. It will focus on a better understanding of atmospheric conditions, currently a major limitation in the development of sparse networks.

全球导航卫星系统技术的许多应用，如测量、绘图和精确导航，要求实时定位精度达到厘米级。 为了支持这些应用，许多国家正在建立密集的连续运行基准站网络，这些基准站的位置通常相距不到40公里。 然而，对于面积大、人口稀少的澳大利亚来说，这些密集的网络在经济上是不合理的。 我们的项目将研究稀疏网络的适当增强，以保持相同的精度水平。 它将侧重于更好地了解大气条件，这是目前发展稀疏网络的一个主要限制因素。
