The growing introduction of automated or even autonomous machinery on farms makes the need for good quality data more critical. Moreover, the demand is increasing to log the outputs of those machines for analysis, documentation and compliance. However, current datafiles sent to, or retrieved from machinery lack quality standards. They cannot be certified because any guarantee on the integrity of the used data and workflow is missing. HASHTAG is therefore leveraging space assets and services to safeguard the reliability of data ensuring trusted application and governance. Within a period of two years, three building blocks will be developed to proof our concept: 1. Standardising protocols, logging and verifying prescribed tasks using machine data flows to assure as-applied maps are trustworthy. 2. Standardising the processing of high quality EO data from Copernicus into prescription maps. 3. Using Galileo’s High Accuracy Service and Navigation Message Authenticator in a GNSS receiver to provide trusted and accurate machine positioning. Integrating these components will result in a workflow capable of generating a transparant and authenticated data chain of EO data to as-applied maps. This is relevant for current reality, where food production and processing are international businesses with ingredients from around the world, governed by food standards and environmental regulations. Our solution, deploying space assets, can be used anywhere in the world, hence leveraging European knowledge and expertise to enable the next level of sustainable and regenerative farming. International partners from Serbia are included and use cases in Brazil, Ukraine and Indonesia will be explored. HASHTAG will reach out to standardisation initiatives in agritech to promote its results and increase impacts. The specific advantages that the European space infrastructure offer, are important to develop globally acceptable and affordable private and public uptake of our space assets.
