TCL1 demonstration outcomes: UAF successfully participated in the NASA UTM Build 1 UAS Demonstration (19 April 2016). UAF was able to integrate with the NASA UTM Manager and UAS client software suite to submit flight plans, track UAS operations in real-time, and close out flight plans upon termination of flight activities. UAF flew four UAS simultaneously in support of NASA goals for the demonstration. This was a significant accomplishment due to a myriad of challenging factors: (1) the short flight times (10-15 min) of most UAS assets; (2) stringent computer-communications requirements for the effort; (3) limitations imposed by early prototype NASA and third party software; (4) changing weather; and lastly (5) the need to coordinate the aforementioned factors with six test sites in four time zones across the US to get all 24 UAS in the air simultaneously. UAF was successful in operating four UAS simultaneously and contributed to NASA meeting its stated goal of 24 UAS flying concurrently during the 1 st flight window (0800-0900 hrs AST). UAF was able to get all four UAS in the air at the same time for flight window 1 (0800-0900 hrs) and flight window 3 (1000-1100 hrs). UAF was only able to launch two of the four UAS during flight window 2 (0900-1000 hrs). Difficulties during flight window 2 were attributed to challenges with multiple data links and implementation of the relatively complex system on a remote location local network infrastructure, with a temporary configuration, which had been set up specifically for this mission. TCL2 demonstration outcomes: During the campaign, UAF successfully demonstrated the flight of 4-5 UAS simultaneously in close-proximity and various profiles, including airspace block altitude-stratified operations and EVLOS altitude-stratified operations. In addition, UAF demonstrated initial capabilities in several key technical areas: (1) successful parachute recovery of the S900 hexacopter; (2) investigation of rudimentary Detect And Avoid (DAA) between two UAS; (3) successful automated landing using laser altimeter using the S1000 octocopter; (4) initial investigation of Real-Time Kinetic (RTK) GPS; and (5) numerous improvements in the design and deployment of the computer-communications architecture supporting NASA's internet connectivity requirements. Several important technical capabilities underpinning the ability to conduct BVLOS flights were developed or furthered, including incorporation of more capable navigation systems, long-range communications, surveillance systems, and geofence technologies. Details of these are provided below. Unfortunately, the short program timeline and limited flight time did not allow all capabilities to be fully realized within the flight campaign itself, but postured the team for future work the UTM program and related efforts within the Initial Pilot Program (IPP). * Navigation. The laser altimeter system on the S1000 octocopter has proven highly successful, providing an unprecedented ability in accurately reporting altitude at high latitudes. The system also provided a new terrain-following capability valuable to scientific research and public service missions. In addition, the RTK GNSS system showed promise for supplying the increased accuracy needed for BVLOS missions involving landing/takeoff activities. * UAS/GCS communications: The program enabled upgrades to UAF's purpose-built long-range UAS/GCS tracking antenna to increase its ruggedness and reliability. The antennas provide the capability of communications at significant distances (20+ km). * UTM remote communications and video: The new video monitoring system performed admirably, providing the capability to remotely monitor launch/recovery operations. Its underlying communications infrastructure also dramatically extended the team's ability to operate using the UTM system via a portable wireless network in remote Alaska locations (which proved necessary for some flights conducted at PFRR).
