What makes it work
FS-SIF-6A Hyperspectral UAV System for SIF Detection
CHNSpec's latest FS-SIF series hyperspectral measurement systems for sunlight-induced chlorophyll fluorescence (SIF) detection include the hyperspectral drone system (FS-SIF-6A). This product is currently the world's leading hyperspectral SIF measurement equipment, using innovative patented optical paths and ultra-high sensitivity detectors with extremely high spectral resolution (0.3nm) and ultra-high signal ratio (600:1).
Key Features
Flexible Deployment
Not limited by satellite transit time; quickly obtains SIF information of vegetation in the study area.
Continuous Time-Series SIF
Compared with fixed tower-base observation, covers vegetation in more areas within a given period.
High Integration
Deeply developed on the DJI M400 with simple operation procedures.
Complete Software Chain
FIGSPEC UAV, MS-PreMerge mosaicking and FIGSPEC Studio image analysis.
Features
The hyperspectral UAV system (FS-SIF-6A) has the characteristics of flexible deployment and is not limited by the satellite transit time. It can quickly obtain SIF information of vegetation in the study area; compared with the fixed observation at the tower base, it obtains continuous time series SIF data, and the airborne platform can obtain SIF information of vegetation in more areas within a certain period of time.
Product Advantages
The sunlight-induced chlorophyll fluorescence (SIF) hyperspectral measurement system can measure the changes in chlorophyll fluorescence (SIF) induced by sunlight in plants by measuring the downward solar irradiance and upward reflected radiation during plant photosynthesis, which is used to estimate the carbon emissions of the two major biosphere carbon sources, Gross Primary Production (GPP) and ecosystem respiration (RECO).
The airborne platform can be used as a supplement to the satellite-borne SIF and tower-based observation schemes. Compared with the satellite-borne platform, it has a flexible layout and is not limited by the satellite transit time. It can quickly obtain SIF information of vegetation in the study area; compared with the fixed observation of the tower base, it obtains continuous time series SIF data, and the airborne platform can obtain SIF information of vegetation in more regions within a certain period of time. The entire system is deeply developed based on DJI M400, with high integration and simple operation procedures.
