• Described UAS in the NAS project & its importance in collecting data useful for evaluation & design of high-reliability UAS C2 links • Large amount of this data was AG flight test data, and this enabled us to gather statistics on fade depths relative to free-space path loss • Propagation models developed • Statistics developed for general use • An important goal for NASA was to make this information available • ITU-R Study Group 3 has created the repository for such information and reviews and approves statistics placed into its Databanks • Table formats were proposed to and accepted by IT-R Study Group 3 • The data was organized and presented to the ITU-R for inclusion in the Study Group 3 Databanks, accepted August 2017 • Wideband statistics are similarly being organized and prepared for submittal to ITU-R Study Group 3.
