The Global Navigation Satellite System (GNSS) has brought a revolution in the science of surveying and mapping. The conventional method of establishing concrete ground control stations on which surveying equipment are mounted and observation carried out has been replaced with the development of Continuous Operating Reference Stations (CORS) that provides a very high level of accuracy. This has created a paradigm shift from Passive to Active Stations of higher accuracy and precision.
OBJECTIVES OF THE NEW SATELLITE BASED SYSTEM
- To provide an all-weather satellite based CORS, that guarantees millimeter to centimeter-level positioning accuracy in real time (24/7), throughout the area of coverage (Abia State)which would enhance the accuracy of mapping, engineering surveys and cadastral Survey, Terrestrial mapping, GIS/LIS applications and other services that require spatial data.
- To provide a framework for the development and maintenance of an accurate Geographic Information Systems (GIS) in Abia State
- To increase the productivity of survey work.
- Providing mm-level accuracy for tracking plate tectonics, subsidence, measuring deformation and contributing to early warning systems.
