Sieat Engineering Pvt. Ltd.

We are a successfully ranked amongst the leading organizations, engaged in providing superior quality DGPS Surveys Service to the clients. Specification The basis of DGPS is "triangulation" from satellites To "triangulate," a DGPS receiver measures distance using the travel time of radio signals To measure travel time, DGPS needs very accurate timing which it achieves with some tricks Along with distance, you need to know exactly where the satellites are in space. High orbits and careful monitoring are the secret Finally you must correct for any delays the signal experiences as it travels through the atmosphere
