The imagery is then tagged with precise location information provided by a Septentrio multi-frequency multi-GNSS receiver (GNSS: Global Navigation Satellite System of which GPS is a part). Many crop issues can be detected with NVDI cameras even before they can be recognized by the human eye. High-quality RGB and NDVI (Normalized Difference Vegetation Index) cameras are coupled with AI image recognition software. Sentera’s sensors are flown by aerial drones to create accurate maps showing crop health, weed and pest locations, as well as plant population counts. This is referred to as direct georeferencing. Sentera, a Minneapolis-based company, is leveraging top-quality GPS + INS (Inertial Navigation System) technology together with their industry leading multispectral cameras and AI to create cutting-edge precision farming sensors.įigure 1: GNSS+INS sensors aboard Sentera's drones provide highly accurate positioning and orientation information enabling creation of orthoimages without the need for software stitching. Open fields are an ideal environment for GPS positioning where satellite visibility is seldomly obstructed. High accuracy GPS+INS opens the door to new possibilities The precision ag market is growing exponentially and, according to forecast reports, will be worth over $10 billion by 2025. Today precision ag and automation is becoming commonplace, from aerial crop monitoring to automated targeted spraying. The concept of precision ag was born around 1990 with tractor guidance as its primary application. Precision agriculture means making the process of crop or livestock farming more accurate and controlled by using information technology and high-tech equipment such as sensors, GPS, control systems and robots. But how to feed the growing population while conserving our forest and wildlife reserves? The answer lies in leveraging technology in order to use our existing agricultural land more efficiently. World population is on the rise, with estimates of 8 billion people by 2025.
