📄️ Product Specifications
Below are the key specifications for Wyvern's imagery data products. For details on spectral, spatial, temporal, and geolocation accuracy, see the tables that follow.
📄️ Spectral Bands
The tables below delineate the spectral characteristics of the hyperspectral imaging sensor on each of the Dragonette satellites. Wyvern strategically operates the hyperspectral imaging sensor on each Dragonette satellite to collect HSI data products with band centre wavelengths that are aligned with existing commercial (e.g., PlanetScope) and science mission (e.g., Landsat, Sentinel, etc.) satellite remote sensing data sources.
📄️ Processing Levels
When placing an order for satellite imagery, users can select the desired processing level to best suit their needs.
📄️ Dragonette Constellation
Wyvern's operational Dragonette constellation consists of 6U cubesat satellites that were launched into low Earth orbit (LEO). All satellites in the Dragonette constellation operate in sun-synchronous orbit (SSO) and provide hyperspectral imaging in the visible and near-infrared (VNIR) wavelengths. Each Dragonette satellite has an orbital period of approximately 15 orbits per day with approximately 24° of longitude ground-track separation between orbital passes at the equator. The imageable latitude range for the Dragonette satellites in SSO is within the range of +82°N to -82°S but at extreme high latitudes imaging is only available for a limited number of days near the summer solstice.
📄️ Calibration and Validation
The calibration of Earth observation imaging sensors hosted on satellite platforms is vital to generate radiometrically and geometrically corrected imagery data that can be scientifically analysed in a consistent manner with ability to perform relative comparison between datasets. A consistent radiometric and geometric correction of imagery data products must be achieved to perform change detection analysis of spatiotemporal collections over time from the same satellite, across multiple satellites in the Wyvern Dragonette constellation, and inter-platform comparisons of datasets acquired from other commercial or science mission satellites (e.g., Landsat, Sentinel, PRISMA, etc.). Consequently, Wyvern has performed a rigorous calibration and validation (cal/val) refinement of each operational satellite in the Dragonette constellation to ensure the best possible quality for every imagery data product.
📄️ Product Delivery
Wyvern delivers imagery data products via Amazon Web Services (AWS) Simple Storage Service (S3) bucket storage and all imagery data products are deemed accepted upon delivery. Each individual client organization will have their own dedicated isolated S3 bucket for imagery data product delivery ensuring confidentiality and privacy is maintained via organizational data isolation while following standard cloud cybersecurity protocols.
