Obtaining UAS flight permit involves execution of Risk Analysis. Gathering and fusing data required for reliable process is laborious and time consuming. GREy provides easy to use web portal with SORA/PDRA/STS/N-STS compliant tools and pre-compiled geo-data repository. GREy team continuously searches for more accurate and up-to-date geo-datasets and blends it into the core repository. GREy tools allow checking flight trajectory against geo-data repository in terms of extended vertical profile as well as population and risk heatmap with built-in accountability mechanisms.

GREy platform is an outcome of ESA founded project - BFPaaS (BVLOS Flight Planning as a Service). Initially designed as a technology demonstrator quickly evolved into fully functional platform due to overwhelming reception from the test users.
