Abstract

Due to the importance of survey work and positioning in any construction project, the opportunity of using new technology is vital to observe high accurate information. Differential Global Positioning Systems (DGPS) represents of most recent innovation in positioning systems. This tool used two types of methods to reduce the error, firstly the gather information from geographic position systems satellites (GPS) comparing it with real fixed ground locations. DGPS can not only improve project accuracy but it can reduce the total survey work in terms of time and cost considerably. However, the high initial cost to buy this kind of equipment prevents many public and private organizations in Iraq from start using this new technology. This research will aim to give real evidence of how accurate DGPS can be. This aim has been achieved via implementing DGPS in a real project and show the real results and compared with standards errors derived from using common survey tools such as Total Station and GPS.
