Performance

Operating mode Remote sensing
Range

365-5000 nm spectral range covered by three hyperspectral imagers:
- VNIR (CASI) - 365-1050 nm
- SWIR (SASI) - 950-2500 nm
- MWIR (MASI) - 3000-5000 nm
Additional sensors on-board forrsimultaneous data acquisition:
- topographic LiDAR (ALTM Gemini), 1064 nm
- high resolution RGB camera, visible light
Additional sensors could be installed on request:
- broadband thermal imager (TABI), 3700-4800 nm
- broadband ultraviolet imager (UVC), 280-375 nm

Resolution

Up to 452 spectral bands in VIS-NIR-SWIR-MWIR spectral range:
- VNIR (CASI) - up to 288 bands (<3,5 FWHM)
- SWIR (SASI) - 100 bands at 15 nm intervals
- MWIR (MASI) - 64 bands at 32 nm intervals

Spatial resolution depends on flight altitude, but for standard campaigns 1000 m flight altitude is used providing:
- 0,5 m/px for VNIR (CASI)
- 1,0 m/px for SWIR (SASI)
- 1,0 m/px for MWIR (MASI)
- 0,25 m/px for topographic LiDAR
- 0,1 m/px for high resolution RGB
- 0,5 m/px for broadband thermal
- 0,5 m/px for broadband ultraviolet

Modifications

Standard ARSENAL setup consists of three hyperspectral imagers covering 365-5000 nm, topographic LiDAR and high resolution RGB camera. Broadband thermal or ultraviolet imagers could be installed replacing some of hyperspectral imagers.
Note! Spectral range 365-5000 nm already includes thermal spectral range 4000-5000 nm with hyperspectral data acquisition possibility.

Operational restriction

ARSENAL is operated as constellation of sensors installed in aircraft BN-2T-4S Defender.

General description

Airborne Surveillance and Environmental Monitoring System (ARSENAL) is a constellation of three hyperspectral imagers (covering VIS-NIR-SWIR-MWIR or 365-5000 nm spectral range), topographic LiDAR, broadband thermal and UV imagers and high resolution RGB camera. The carrier of ARSENAL is aircraft BN-2T-4S Defender .
