AREA(S): Air Platform, Electronics
PROGRAM: PMA 266 Navy and Marine Corp Multi-Mission Tactical UAS
Develop a software application capable of assessing the level of safety of
various detect and avoid (DAA) technologies as they might be integrated on an
unmanned aircraft (UA) operating in representative operational environments.
In order to operate in civil and military airspace, Navy UA use DAA
technologies and procedures to facilitate sharing airspace with other
aircraft. The capability to operate safely anywhere in the world must be
demonstrated before the UA receives approval for operational missions. Due to
the potentially catastrophic consequences of error in the operation of the DAA
systems, rigorous safety analyses are required to gain confidence in system
effectiveness before deployment of the UA into airspace with manned aircraft.
Safety analysis should be conducted to determine whether the DAA sensor
system’s performance (e.g., detection ranges, field of view, etc.) provide the
UA operator timely and adequate information to maintain separation from
intruding cooperative and non-cooperative aircraft by executing appropriate
avoidance maneuvers with very low false track rates presented to the operator.
I: Design, develop, and demonstrate feasibility of a comprehensive and detailed
architectural description of the software application. Identify all inputs
(e.g., DAA sensor models, encounter characteristics, maneuver models,
latencies) and outputs (e.g., risk ratios, encounter statistics). Identify
sources of necessary inputs such as airspace characterizations. Describe and
justify the level of fidelity of individual models. Validate the approach
using a variety of representative problems. Prepare a complete application
development plan, including prototype plans to be developed under Phase II.
II: Develop, demonstrate, and validate the prototype application for use within
the Navy. The validation cases and metrics will be provided by the Navy.
Prepare a Phase III development and support plan to transition the technology
to the Navy.
III DUAL USE APPLICATIONS: Perform any final testing and fully transition the
technology to the Navy. Extend the application to support DAA sensor
certification by civil authorities. Successful technology development should
be equally applicable for the analysis of DAA sensors for certification in
national airspaces governed by civil authorities.
