	Sensor	Description
	EO/IR sensor - Laser illuminator - Laser range finder	EMSA RPAS carry Electro-Optical/Infrared (EO/IR) gimbals. Electro-optical (EO) sensors provide true-colour optical images for the detection and identification of objects, mainly in daylight. Infrared (IR) sensors extend operations to night-time and low-visibility conditions, and thermal infrared sensors can detect the heat emitted by objects and work day and night. Some systems also include a laser range finder (to measure distance using a reflected laser pulse) and a laser illuminator (laser beam to highlight a target).
	Maritime Radar - Doppler radar - Synthetic Aperture Radar (SAR)	Maritime radars provide real-time detection and tracking of vessels and other objects by continuous scanning of the sea surface. These are all-weather, day-and-night capable sensors, combining wide-area search, detailed imaging, and moving target detection.
	Emission monitoring sensor	A gas sensor measures ship exhaust emissions at sea and in ports, detecting levels of pollutants such as SO_X. Data on fuel sulphur content can support authorities interested in verifying vessel compliance with fuel sulphur limit.
	Automatic Identification System (AIS) receiver	This sensor can receive AIS signals broadcast by ships, containing information such as position and identifying details to support an overview of maritime traffic in the area where the RPAS is flying.
	Optical scanners	Uses optical and infrared images sensors to scan automatically the sea surface to detect objects of interest using algorithms to interpret the images collected. The images used in the processing can be collected from the sensors in the main gimbal (see EO/IR sensor above) or standalone through a standalone gimbal.
	Emergency Position‑Indicating Radio Beacon (EPIRB) receiver	An Emergency Position-Indicating Radio Beacon (EPIRB) receiver detects and locates distress signals emitted by vessels or individuals, to support quick reactions to incidents at sea and provide accurate information during search and rescue operations.
	Mobile phone frequency detector	For the detection and geolocation of mobile phone signals in the maritime environment to assist in search and rescue operations.
