Leverage Precise Geolocation Technology for 5x Faster Ag Data Delivery

From pre-flight planning to in-the-air image capture to post-processing, the Sentera Direct Georeferencing (DGR) System increases efficiency and reduces total project time by nearly 90% — helping agronomic leaders capture more data, faster so they can focus on data validation and outcomes.

How it Works

  • Get ready for flight.

Instead of defining ground control points, prepare for your flight by quickly connecting the DGR System to the DJI M300 Drone: Add tactical-grade inertial measurements (IMU) and dual RTK GPS functionality) in just a few steps.

  • Fly and capture data.

Because images require 50% less overlap, capture 9x fewer images for analysis. The result? Faster flights – from 45 minutes to less than 20!

  • View and analyze key data.

With 5x faster data delivery, focus time on analyzing data and measurements to make faster and more precise critical decisions.

  • Upload data for post-processing.

The Sentera DGR results in absolute location certainty. With an output of spatially accurate maps right at the field’s edge, no need to rely on stitching to create an orthomosaic.

Paired with 6X Sensors- Science-grade Multispectral Imagery

With eight channels of image data, Sentera’s 6X Multispectral and 6X Thermal sensors deliver fast-frame rate performance combined with high radiometric accuracy for more advanced imagery.

 

More Advanced Imagery With Radiometric Accuracy

Pair with radiometric calibration tools, like Sentera’s Calibrated Reflectance Panel and Light Sensor, to account for lighting varations; meaning you get accurate and reliable imagery.

 

 

Plant-By-Plant Measurements, Delivered

From identifying crop health to informing trait selection and product development decisions, the 6X Sensor from Sentera delivers science-grade imagery with eight-channels of data to get insights down to the leaf.

 

Pixel-Level Temperature Measurement

The 6X Thermal Sensor features a built-in 320 x 256 Boson® thermal sensor to deliver thermal accuracy of ±5°C and accurate thermal maps at a GSD of 17.7cm (7.0″) from 60m (200ft) flight altitude.
