GNSS-enabled Precision Agriculture

Abstract

Global Navigation Satellite Systems (GNSS) have revolutionized precision agriculture, enhancing productivity and sustainability. This chapter delves into the integration of GNSS in modern farming practices, highlighting its pivotal role in precision agriculture (PA). GNSS technology provides precise location data, enabling accurate soil sampling, variable rate technology (VRT), precision planting, and yield mapping. These applications optimize resource use, minimize environmental impact, and increase crop yields. The chapter also explores the vulnerabilities of GNSS, including signal interference and economic barriers, and discusses potential solutions. Furthermore, it examines the integration of GNSS with emerging technologies such as Geographic Information Systems (GIS), unmanned aerial vehicles (UAVs), the Internet of Things (IoT), and advanced sensor technologies. Case studies demonstrate the effectiveness of GNSS in diverse agricultural contexts from automated irrigation systems to robotic harvesting. Despite challenges, the future of GNSS-enabled precision agriculture looks promising, with advancements in signal accuracy, satellite constellations, and receiver sensitivity. This integration is set to transform agriculture, ensuring efficient and sustainable food production. By leveraging GNSS, farmers can make data-driven decisions, enhancing productivity and reducing waste. This chapter underscores the critical role of GNSS in achieving global food security and sustainable agricultural practices. © 2025 selection and editorial matter, Dileep Kumar Gupta and Abhay Kumar Singh; individual chapters, the contributors.
