Locate electromagnetic emissions

Assessment tool

Version 1.0
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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria of this unit and include demonstration of applying:

the underpinning knowledge and skills

relevant legislation and workplace procedures

other relevant aspects of the range statement

convert a magnetic line of bearing to a grid line of bearing for triangulation compilation

triangulate the location of the isolated emission within a specified and acceptable margin of error

Consistency in performance

Competency should be demonstrated in a range of direction finding activities conducted over time utilising current specialist sensor equipment and procedures to ensure the candidate is assessed across a variety of relevant workplace situations, direction finding systems, and target communications environments.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment.

Specific resources for assessment

Access is required to organisational guidelines and procedures


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level, required for this unit.
