Development and Experimental Analysis of SCM GPS-based Farmland Area Measuring Device

摘要

For the needs of operating area measurement in the current agricultural production, area measuring devices are developed by the application of MCU and the common GPS module, with characteristics such as: low cost, easy to carry, easy to operate. Area calculation principle is analyzed, combined with smaller storage capacity, relatively low complexity of computing power of SCM, appropriate algorithm is designed to ensure the high-speed, accurate calculation. Measured results show that the measurement accuracy meets the production requirements.
