基于RTK差分GPS的平地机作业质量评估

The Assessment of Quality of the Grader Based on RTK Differential GPS

为了取得平地机作业质量数据,评估RTK差分GPS平地机作业质量效果,对853农场约0.3 hm^2水田进行了搅浆平地试验。先使用了传统的农田作业质量评估方法来对其进行简单的初步评估,为了得到更加准确的评估数据,再使用了精确的农田质量评估方法。评估结果表明,使用RTK差分GPS平地机进行农田平地作业,能够满足农田平整精度要求。

In order to get the date of land leveling quality and the quality of real-time kinematic（RTK） global positioning system（GPS） grader. The ground tesr was carried out on paddy field which is about 0.3 hm^2 in 853 farms. The traditional methord to analysis the quality of land leveling was used at first. The next step is obtain the more accurate date. A precise method of farmland quality assessment is used to evaluate the results of the assessment. The evaluation results show that using the RTK differential GPS technology to carry out the farmland leveling,it can meet the requirements of farmland leveling accuracy.
