Under Sensors and Advanced Flight Systems, we emcopases a broad research areas that include:

Current topics:

Guidance, Navigation and Control	Mission Planning Trajectory Generation Global Navigation Satellite Systems (GNSS) Multi-Sensor Navigation Systems Vision-Based Navigation Control Systems for Collision Avoidance Applications


Sense-and-Act	Computer Vision based “Sense and Act” for UAS UAV Guidance & Control for UAVs “Sense and Act” Detection of Dim Sub-pixel Targets for UAV Collision Avoidance using the Hidden Markov Model and Morphologically Processed Imagery


Flight Termination	Candidate Landing Site Identification and Classification Through Machine Vision Techniques Multicriteria Decision Approaches Applied to UAV Forced Landing Navigation and Trajectory Planning for UAVs


Propulsion	Hybrid Propulsion for UAS Multi-objective mission planning for UAS with hybrid propulsion systems


Smart Payloads	Infrastructure Inspection and Monitoring Search and Rescue Aerial Photography using Fish Eyes lenses Onboard Sense-and-Act

Emerging Topics:

There are currently opportunities to undertake research at ARCAA in the following topics:

*Vision-based Guidance of UAVs*	Description: Computer vision has been acknowledged as one of techniques that can provide the richest amount of information. The research deals with he development of techniques to enable/enhance the navigation capabilities of UAVs using vision systems.


*Vision-based detection of targets at sub-pixel resolutions*	Description: When using image processing for sense-and act, collision threats depending on the distance, may appear as small subpixel resolution 'spots' - this research focuses on the development of algorithms for the detection of targets exhibiting these properties within images


*Centralised/decentralised control of the airspace*	Description: The two existing dominate paradigms for “network control” are decentralised and centralised control. However, in the presence of data-limited communication links, and measurement uncertainty, there might be other options for achieving safe operation. One option is a *“negotiated”* control paradigm (a negotiated mixture of decentralised and centralised controllers).
