Sentera’s Quad sensor is now available in an integrated, gimbal-stabilized package for DJI Inspire and Matrice drones.
Featuring four customizable and individually filtered focal plane arrays, the Quad features Lock and Go technology, providing simple, snap-in installation to the drone. The technology also actively stabilizes the optics to true nadir, optimizing productivity while capturing high-precision, low-distortion vegetative health data. Image products are compatible with most standard stitching and GIS tools, Sentera notes.
In standard configuration, the Quad sensor offers access to standard normalized difference vegetation index (NDVI), green NDVI, normalized difference red edge (NDRE) and high-resolution color data capture – all in a single flight. Simultaneous collection of NDVI and NDRE data provides users with informative, accurate insights about crop health while streamlining operations, the company says.
“A gimbaled sensor ensures consistent camera positioning and consistent incident angle to the ground, regardless of flight direction, wind or vehicle dynamics,” explains Ethan Oscarson, mechanical engineer at Sentera. “By maintaining a consistent angle of incidence, operators can be confident that their spectral data is accurate and isolated from random spectral bias induced by phenomenon like BDRF (bidirectional reflectance distribution function). This is particularly important with the precise, narrow-band spectral data provided by this sensor.”
Greg Thompson, director of sales at Sentera, adds, “Swapping payloads on the go gives our customers the ability to decide what data they want to collect while on-site. Advisors and researchers are scouting multiple fields in a single day. Data capture flexibility allows them to customize a crop scouting mission based on their requirements.”
Sentera claims the Quad is the only plug-and-play, gimbaled, multispectral sensor available for the DJI Inspire family. The sensor can be configured to capture any optical frequencies in the visual and NIR spectrum. It’s an ideal solution for universities, researchers, large growers and advisors with specialized data-gathering requirements, the company says.
