📄️ 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.
📄️ Data Processing & Product Generation
To deliver hyperspectral imagery data products in a consistent, scalable, reliable, and timely manner Wyvern has built a cloud-based data processing pipeline that converts raw sensor data and platform ephemeris metadata into usable output imagery data products that are delivered to end-users. The data processing pipeline includes spectral band co-registration at a < 25% subpixel level to ensure the best possible spectral purity in each pixel thereby enabling robust spectral analysis of the HSI data products.
📄️ Processing Levels
When placing an order for satellite imagery, users can select the desired processing level to best suit their needs.
📄️ Quality Assurance
Wyvern has built an advanced proprietary image quality assurance (QA) system to confirm that imagery data products align with the documented standard product specifications and the offering's cloud cover policy. If the quality assurance system determines that a new tasking imagery data product does not meet the standard performance specifications or cloud cover policy and there is available imaging capacity the Wyvern constellation tasking system will automatically re-schedule a new imaging collection attempt within the tasking order's time-of-interest (TOI) acquisition date range. This automatic QA standard performance specifications misalignment retasking applies to both Standard Tasking and Premium Tasking offerings where available imaging capacity for re-schedule is offering- dependent. New tasking attempts will continue until an imagery data product is acquired that aligns with standard product specifications or the constellation tasking order's acquisition date range expires. Furthermore, for Premium Tasking orders with automatic cloudy collection retasking if an imagery data product does not align with the cloud cover policy the Wyvern constellation tasking system will automatically re-schedule a new tasking request to attempt another imaging collection within the order's acquisition date range based on available Premium Tasking capacity and upcoming weather forecast (automatic cloudy collection retasking is not available for Standard Tasking which is a single shot offering).
📄️ 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.
