Economy of scale! Unification of the backbone reference network! Georeferencing alignment of all sub-contractors on a single project! The mandatory foundation that unifies all Geomatics systems & solutions? Demystification of the complexity of Geodesy increases the customer base for High-Accuracy positioning! Modern GNSS Network RTK & DGPS solutions have created all these claims since they first appeared in Western Europe in 1999 (Germany). The adoption rate of GNSS Network RTK in particular has been growing at an exponential rate over the last 3-4 years, and on a global basis. Whether it be for the reference backbone for a national cadastral reform, or for the rebuilding of Iraq or even for the need to georeference a GIS or Utility distribution application, the emergence of GNSS Network RTK has provided a significant role in providing a common ubiquitous benefit to the society at large, and particularly for the surveyors and engineers who depend on high-accuracy positioning to perform their mandates.

GNSS Infrastructure can be compared to other networks - such as electrical grid or gas pipeline - that provided our societies with an improvement of our quality of life in our history, and generated a new "economy of abundance" from their inception. It is now also recognized by major financial institutions (WBN, IDB, ADB, etc) as a necessary structure to fund the development of a modern country in the 21^st century. Looking a specific recent applications around the world and implementation models used to provide this high-positioning accuracy service/solution allows a better understanding of the common benefits, and difference in implementations that are possible when approaching this complex investment, particularly for a nation-wide service with a high service-level performance commitments. It used to be someone had to read an instruction manual to operate a toaster. The same will soon be true of operating a complex sensor-solution for high accuracy RTK positioning.
