ISKANDARnet CORS network integrity monitoring

The increasing use of real-time high precision Global Positioning System (GPS) methods has leads in raising number of Continuously Operating Reference Station (CORS) establishment. However, it is complicated to expect the disparity in the performance and status of the reference stations. Thus, a system for dealing with data quality control in order to supervise data streams in real-time has been proposed. This paper focuses on the number of existing approaches to review the quality of raw GPS observations and presents architecture for the development of a real time quality control system in Peninsular Malaysia.
