Dragonette
Wyvern’s Dragonette hyperspectral satellites capture the Earth’s surface in up to 32 spectral bands across the visible and near-infrared (VNIR) range with a 5.3-meter spatial resolution at nadir. This enables the detection of unique chemical and physical properties invisible to the human eye, making Dragonette ideal for applications such as wildfire detection, food security and environmental monitoring.
Wyvern offers flexible licensing, multiple delivery options, as well as customizable plans to meet specific project requirements.
