Issue Date: March 2024
This unit was designed for Defence personnel working within the electronic warfare and signals intelligence fields but may be applicable to any individual employed within a similar role.
Typically individuals perform this activity independently with indirect supervision. The application of this unit in the workplace involves the use of specialist sensor equipment to establish a magnetic line of bearing to the source of an emission, and the triangulation of multiple sensor bearings to determine the best point estimate of the transmitting antenna’s location.
All activities are carried out in accordance with relevant standard procedures.
This unit covers the competency required to establish the direction from which a received emission was transmitted ("direction finding") from the clandestine or overt interception of a transmitted electromagnetic emission ("intercept"). This unit also covers the production and reporting of a triangulated emission point-of-origin assessment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. In a Defence context, this means that there is no civilian need to hold this unit in order to meet licensing, legislative, regulatory or certification requirements.
