How DGPS Surveys Are Performed in India? Precision of Geospatial Data Collection
In the field of geospatial data collection, Differential Global Positioning System DGPS surveys in India have become a vital technique for achieving accurate positioning and mapping. This blog explores how DGPS surveys are performed in India, highlighting the methods and technologies employed to ensure precise and reliable geospatial data. Understanding DGPS Surveys DGPS surveying companies in India utilize a network of reference stations to correct GPS signals, significantly enhancing the accuracy of positioning data. By comparing the GPS signals received at the reference stations with those received by a mobile receiver, errors caused by atmospheric disturbances and satellite clock discrepancies can be mitigated. This correction process allows for precise positioning measurements with sub-meter or centimeter-level accuracy. DGPS Surveying Process in India: In India, DGPS surveys are performed using the following steps: Establishing Control Points The first step is...
