| Abstract: | Global Positioning System plays an important role in precision agriculture. In this study, a new instrument was developed to measure field area based on GPS module. The instrument mainly consists of a low-cost GPS module, a micro-controller based data acquisition board, a keyboard, and a LCD display. The acquisition of GPS positioning information, method of area calculation for polygon fields, and design of hardware and software of the instrument were also introduced. Tests showed that the instrument was capable of rapidly measuring fields of any shape, the relative test error was less than 2 percent, and the measuring accuracy was improved to suit its application in larger fields. |
