Remote Operation for Autonomous Missions (ROAM) UAS Operations Center

On September 30th, 2021, the High Density Vertiplex (HDV) team began data acquisition testing in support of the Advanced Onboard Automation (AOA) Simulation (AOA Sim) test. The AOA Sim test has several objectives and also represents a significant increase in sUAS research and testing capability for NASA. One objective of the AOA Sim test is to fully test autonomous system integration in support of subsequent flight testing. Other objectives of AOA Sim are: 1) acquire human factors data regarding HDV UAM Ecosystem prototype assessments; 2) contribute to safety and risk assessments associated with planned beyond visual line of sight (BVLOS) operations; 3) provide critical training for the sUAS operations team; 4) and support collaborative research objectives of the TTT Revolutionary Aviation Mobility (RAM) project. The basis for the AOA Sim facility is the integration of a 6 degrees of freedom (6-DOF) sUAS simulation model with the same autopilot that will be used for flight. Another significant element of AOA Sim is the Remote Operation for Autonomous Missions (ROAM) UAS Operations center that has been created within the Air Traffic Operations Lab (ATOL). The ROAM UAS Ops center provides the capability to establish a shared situational awareness environment for the sUAS operations team enabling advanced sUAS operations such as BVLOS. Both simulation and flight testing are performed using the ROAM UAS Ops center. Integration of the ROAM UAS Ops center with the Airspace Operations Lab (AOL) and Autonomous Vehicle Application Lab (AVAL) at NASA ARC to support UAM Ecosystem prototype assessment testing objectives has also been completed. ARC developed systems include: 1) the xTM Client which supports fleet management functions, 2) integration with the NASA provider of services for UAM (NPSU) systems, and 3) simulated air traffic. The AOA Sim test is planned to run through the end of October. The HDV sub-project is part of the Advanced Air Mobility project and the AOA Sim start of data collection completes a Level 2 milestone.

X4 Corridors presented to Executive Board Working Group (Conops) for UAM operations
October 1, 2021

The UAM Sub-Project’s technical area Airspace Procedures and Design (APD) presented corridors designed for the upcoming X4 simulation to a Joint NASA-FAA Executive Board Working Group focused on a concept of operations for Urban Air Mobility. There has been a close collaboration between the FAA and NASA on development of a concept of operations for UAM operations. In June 2020, the FAA released UAM Conops version 1.0, which among other ideas also introduced the idea of corridors where UAM operations would be strategically deconflicted by the design of the corridors and sharing intent among operators. Also, tactical separation would be managed by operators rather than air traffic controllers by using a combination of software on the ground and on-board as well as equipment on the vehicles. The corridors designed for the X4 simulation, planned with National Campaign Airspace industry partners, identified airspace in the Dallas Fort-Worth area that was deconflicted from traditional traffic. The design utilized standard approach and departure procedures and historic track data to deconflict the airspace from the traditional traffic so that ATC did not have to intervene and provide services inside corridor airspace. The APD Team also presented approach and departures procedures identified for the X4 simulation and a preliminary analysis of routes inside the corridor airspace. Both NASA and FAA participants provided feedback on the corridors that will be incorporated into the next series of simulations. Future work will involve further fine tuning the airspace construct-corridors based on feedback from X4 simulation and data analysis.
