2025: Presentation of Single-Sensor Multispectral SWIR Camera for ALS
Geoskan Group of Companies and the Scientific and Technological Center for Unique Instrumentation of the Russian Academy of Sciences have created a domestic single-sensor camera for multispectral shooting from drones in the SWIR range. The camera differs from previous Russian solutions in the high resolution of images and the ability to simultaneously shoot in four spectral intervals. This expands the capabilities of unmanned technologies for scientific and industry tasks in the SWIR range: from geological exploration and monitoring of an oil spill to assessing the state of vegetation. Geoskan announced this on December 3, 2025.
The SWIR (Shortwave Infrared) survey allows you to record reflected radiation in the wavelength range from 900 to 1700 nanometers and obtain data that is not available in the visible spectrum. Thanks to this, with the help of a camera, it is possible to determine the mineralogical features of rocks, soil moisture and the state of vegetation.
The camera simultaneously captures the image in four spectral intervals and transmits data to one sensor with a resolution of 4.8 megapixels (previously, for matrices in this range, it was considered a high resolution of 640×512 pixels (0.3 megapixels). This operation of the system ensures high shooting speed and accurate alignment of channels. As a result, four images are formed in one frame in each spectral range of the camera - TIFF files, ready for loading into Agisoft Metashape data processing software.
The equipment was tested on the Geoscan 201 ALS. The results of the tests showed the clarity of the images, low noise levels and stable image formation in four SWIR-band channels. The camera provided the image overlap required for further photogrammetric processing. The improved firmware of the system made it possible to automatically adjust the exposure of the camera.
 | The SWIR camera is a compact and efficient system for solving a large range of applied tasks in geological exploration, environmental monitoring, agriculture and forestry. Due to the global shutter, the shortcomings of scanning cameras have been eliminated here, and the high resolution of the matrix has made it possible to make a 4-channel camera at a price comparable to a single-channel one, "said Nikita Prokofiev, project manager of the Geoskan Group of Companies. |  |
| | A multispectral SWIR camera based on the separation of the optical stream allows you to implement several spectral channels in one device using just one sensor. The developed system does not require scanning, has a mass of less than 100 g, is compact, easy to install and use. This makes the camera very promising for installation even on small BVS with a low takeoff weight, - commented Alexander Machikhin, head of the laboratory at the NTC UP RAS. | |
In 2026, Geoscan plans to integrate the system into other ALS models for aerial photography: Geoscan 401 and Geoscan 701. This will expand the ability to monitor water bodies, conduct multispectral and geological exploration surveys both for work at low altitude with a detailed contour of the relief, and in vast areas.
