ACCURACY ASSESSMENT OF UTP GPS CONTINUOUSLY OPERATING REFERENCE STATION FOR SIMULATED STRUCTURAL DEFORMATION MONITORING

Accuracy is a degree of closeness a set of data from series of measurement to
its true value and data set could be said as precise if the value is close to the average
value of the quantity that being measured. Data measurement for any engineering
applications cannot be perfect but the accurate data is important especially when it
comes to the human safety. Recently Universiti Teknologi PETRONAS (UTP) has
established a continuously operating reference system (CORS) which can be used by
Global Positioning System (GPS) users to enhance the accuracy of their application.
However, being new the accuracy performance has been assessed. Therefore, this
study took the initiative to assess the accuracy of the CORS, in two variables which
are baseline between CORS and users as well as amount of data used to provide the
positioning.
