Abstract:
Measuting highly accurate positions by GPS truly needs appropriate selection for equipment, field procedure, and proper processing methods. For high accuracy positioning applications (cm level), GPS static relative positioning method is usually employed. After the data collection task is completed, the data will be processed by commercial software obtained toggther with the GPS receiver. Since GPS data processing methods are quite complicated and those methods belong to an individual provider, commercial softare, which is currently available in the market, does not allow users to explore steps and models employed in the data processing. Besides, applying different methods and models to process the data with the software cannot be done. This research focuses on developing a Matlab-based GPS data processing software for static positioning. According to characteristics of Matlab that can easily be understood, the users gain opportunities to perceive steps, methods, and models applied within the software thoroughly. The developed software will be useful for other related studies and research in the future. In addition, initial results obtained from processing real GPS data with the developed software show that the outputs from the developed software and a commercial one provide the same degree of accuracy.
