Global Positioning System (GPS)

The presence of GPS technology, data acquisition opportunities coordinates (latitude, longitude, and height) quickly, accurately, and with good accuracy. Specification of GPS devices available in the market is very diverse, ranging from the type of handheld / navigational accuracy at the level meter, to the geodetic type which can reach millimeter accuracy level to level. Along with the need for survey and mapping applications are increasingly "rely on" the GPS, then the required method of data acquisition positions or coordinates with high accuracy but with strategy and data processing of GPS measurements are relatively quick and easy. This is especially very useful if the data acquired include hundreds or even thousands of points within a network on a survey and mapping project.

This is what underlies Geomatics Research Institute to conduct research entitled "Optimization of GPS Measurement Results." This study aims to provide alternative methodologies / strategies and the measurement and calculation algorithms of GPS data that can be utilized in the application of survey and mapping work.

The focus of this research is the selection of GPS measurement methods: static, kinematic, real-time kinematic. Emphasis is directed to methods of real-time kinematic (RTK) as a relatively new and has not been widely applied widely. Also selection of GPS data processing methods investigated further: the optimization of the network, optimizing the parameters of supporters (atmosphere, ocean tide loading, efemeris planets, etc.) and also the optimization of high data acquisition from GPS.

Thus the results of this study will be useful for practical applications of surveying and mapping, particularly in the context of positioning / coordinate for engineering work in a fast, easy and (relatively) cheap. The results of this study also supports the basic tasks and functions in providing BAKOSURTANAL / create the National Spatial Data Infrastructure (NSDI) and standardization of methodologies with GPS positioning.
