农业植保无人机高精度定位系统研究与设计——基于GPS和GPRS

农业植保无人机凭借其高效率、低作业成本等特点,目前正逐步地取代人工植保,成为农业植保领域的一种重要装备。定位系统作为农业植保无人机控制系统的核心,是实现无人机自主工作和飞行的关键,也是无人机进行各项植保飞行作业的基础,研发和设计高精度的无人机定位系统是未来农业植保无人机技术进一步突破和应用的关键。为此,针对GPS定位系统在复杂环境下的稳定性差、定位精度有限、无法为农业植保无人机提供高精度稳定的定位服务的问题,提出了一种基于GPS和GPRS的混合农业植保无人机高精度定位系统的设计,通过该系统可以有效地弥补GPS在复杂环境的定位不足,提高农业植保无人机的定位精度,对进一步促进农业植保无人机技术发展具有非常重要的意义。
