Paper Abstract

In this spring, the worst drought to hit China's northern wheat-growing belt in half a century. How to make proper decision to fight drought is a vital problem to Chinese government. Of course, this is a complicated problem for many factors involved. But for surveyor, we must provide the drought area, different drought levels and position information quickly. Real Time Kinematic (RTK) satellite navigation is a technique used in land survey and in hydrographic survey based on the use of carrier phase measurements of the GPS, GLONASS and/or Galileo signals where a single reference station provides the real-time corrections of even to a centimetre level of accuracy. In this paper, we discuss the application of GPS technology in fighting drought. Firstly, we introduce the RTK technology and its applications in other field. Secondly, according to the requirement of fighting drought, we give the scheme of how to get the information of drought area, different drought levels rapidly. Thirdly, we discuss the technology of real-time positioning to artificial rainfall using aeroplane.
