REMOTE SENSING & UAVS

Sensors that can quantify factors related to crop, animal, and woodland production and environmental management are the foundations of digital management.  When those sensors are interconnected and communicate in real time, that concept is Internet of Things, or IoT.  Sensors can be mounted on satellites, airplanes, unmanned aerial vehicles or drones, ground-driven implements, or in fixed or semi-fixed locations on plants or animals or in the soil.  Common measurements include geographic coordinates, electromagnetic reflectance within the visible, near infrared, thermal, and other spectrums, temperature, pressure, speed, resistance, vibration, and humidity.

Key Terms

Ionosphere

Atmospheric layer that exists from 50 to 250 miles above the earth’s surface and contains electrically charged particles.

RADAR

(RAdio Detection And Ranging) A method of estimating the distance or travel speed of an object by bouncing high frequency signals off the object and measuring the reflected signal.

Precision

The repeatability of multiple measurements of the same object or condition.

GPS Antenna

A device that receives satellite signals from GPS satellites. On smaller hand held devices such as a smart phone the antenna is integrated into the device. For machine GPS systems, the antenna is often an external device mounted on top of the vehicle, away from the receiver.
