GPS Surveying

GPS Surveying. Instructor: Prof. Jayanta Kumar Ghosh, Department of Civil Engineering, IIT Roorkee. The objective of the course is to provide optimal insights into land surveying using GPS (Global Positioning System). The course starts with an introduction to land surveying leading to GPS as the state-of-art for surveying of land. Then, different aspects of GPS systems such as GPS architecture, GPS signals, GPS receivers, GPS software has been discussed followed by GPS positioning and GPS observables. Next, it provides GPS processing fundamentals consisting of pre-processing and processing steps under different processing strategies followed by quality assessment and eld procedure of GPS surveying. The course concludes with a detailed demonstration of GPS field surveying followed by processing of collected data. (from nptel.ac.in)
