Is it feasible to conduct crop health monitoring using PSRI for intercropped fields, or is it limited to monocrops?
Crop health monitoring is feasible with PSRI (Plant Senescence Reflectance Index) for intercropped fields with our dataset; however, its effectiveness depends on the crop density.

How to use Change detection model?
Change detection is a generic model designed to assess changes between a pair of layers stemming from identical models (such as LULC) or analytical outputs (such as NDBI, SAVI). The model provides ...

How to access Pixxel imagery on Aurora?
Click on the Constellation icon located on the right-hand side of the page. Select the constellation you wish to view and explore Pixxel imagery.

Is Crop-Bio parameter model applicable for Hyperspectral images?
Yes, Crop Bio-parameter model is suitable for Hyperspectral Imagery. The crop biophysical and biochemical parameters model estimates crop leaf area index (LAI), chlorophyll, and brown pigment. Inpu...

Is it possible to detect rare-earth elements using hyperspectral imaging (HSI)?
Yes, detecting rare-earth elements using HSI (Hyperspectral Imaging) is feasible. The common method for achieving this is by employing Spectral Signature Matching techniques such as SAM (Spectral A...

What atmospheric corrections are used in Hyperspectral data?
The atmospheric corrections used are1. The pHSICOR model, Pixxel's copyright model, includes corrections for aerosol and water vapour 2. IsoFit model

Is hyperspectral imagery data also utilized in urban forestry analysis, and what methods are employed to address spectral unmixing with other urban features?
Pixxel HSI data has a 5-metre spatial resolution and might be suitable for scenarios where landscape changes are quite drastic in an urban setting. Spectral Unmixing techniques could be used to der...

What level of calibration degradation can be expected over time? What is the anticipated level of calibration stability after a year of deployment?
The calibration activity is carried out every 1/2 months. All the Pixxel satellites will be inter-calibrated. The effect of both the sun angle and look angle on the data from different satellites, ...

Will Pixxel satellites provide global continuous coverage?
1. We are not just a Tasking constellation, we follow a hybrid approach as well. We will be regularly monitoring and archiving many large areas that are of high interest globally such as the Amazon...

Are the satellite orbits structured to consistently observe at the same time of day?
Our satellites are planned to observe the every location at the same (local) time of the day; but they have a different NADIR revisit.
