Overview
Dragonette-1 is the first satellite in Wyvern's hyperspectral constellation, launched in April 2023. As a pathfinder mission, it demonstrated Wyvern's innovative approach to affordable hyperspectral imaging from space, delivering 23-band VNIR data at 5.3-meter resolution.
Hyperspectral Capability
With 23 contiguous spectral bands spanning the visible to near-infrared range (500-800nm), Dragonette-1 provides detailed spectral signatures for:
- Crop health analysis - Detect plant stress before visible symptoms appear
- Species identification - Distinguish between vegetation types and crop varieties
- Water quality - Monitor chlorophyll, sediment, and pollutant levels
- Mineral mapping - Identify surface mineralogy and soil composition
Spectral Resolution
The 23 VNIR bands provide continuous spectral coverage with narrow bandwidths (~20-32nm FWHM), enabling:
- Spectral unmixing - Decompose mixed pixels into component materials
- Red edge analysis - Precise vegetation health metrics from the 690-750nm region
- Chlorophyll estimation - Multiple bands targeting absorption features
Applications
Dragonette-1's hyperspectral capabilities support:
- Precision agriculture - Variable rate application and yield optimization
- Forestry - Forest health monitoring and species mapping
- Environmental monitoring - Ecosystem assessment and change detection
- Mining - Exploration support and environmental compliance
