Geoscan Pollux

This is a multispectral digital camera designed and manufactured by Geoscan with the use of the latest components and technologies.

Compared with competitors, Geoscan Pollux is distinguished for its higher detail and performance, thanks to the 1.5 MP Sony sensors and fast lenses at all the five bands.

Advantages

Going into detail

Higher image size and longer focal lengths make images more detailed. For example, from fixed-wing UAVs, which minimum altitude is limited, Geoscan Pollux makes it possible to obtain GSD of 5.2cm (at 120m AGL).

Transmission characteristics of filters

The Geoscan Pollux camera is compatible with different UAVs. You can purchase it separately or as a part of Geoscan Lite, Geoscan 201 and Gemini.

Go to catalogue

The Geoscan Pollux Multispectral Camera provides simultaneous captures in five narrow bands (12-40 nm). In addition to the main bands of the visible spectrum (Blue, Red and Green), the camera registers Red Edge and IR, which makes it possible to calculate various vegetation indices: SAVI, NDVI, NDRE, LAI, etc.

Survey data can also be used to build digital terrain models and pseudo-color composites, allowing to achieve color separation of cultivated plants and weeds.
