What an assessment for ICTRFN806 must cover

40 assessable components: 4 elements (12 performance criteria), 4 performance evidence and 13 knowledge evidence requirements, plus 11 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Research satellite communication systems

1.1Research satellite applications with various orbit types and assess their spatial positioning for specific purposes
1.2Analyse and report on architecture, major subsystems and critical components in communication systems of recently launched commercial satellites
1.3Research and report on multiple access techniques and their typical applications

2 Analyse uplink and downlink variables

2.1Determine uplink and downlink criteria that impact on carrier-to-noise ratio
2.2Determine up/down link criteria that impact on baseband signal-to-noise ratio
2.3Determine critical parameters of satellite system
2.4Research common types of baseband signal processing, and their spectral and noise improvement parameters and determine criteria for link budget evaluations

3 Conduct link budget analysis

3.1Produce satellite link budget and calculate link margin for satellite system with specified modulation types
3.2Analyse relationship between bit-error-ratio (BER) for given energy per bit-per-noise power density (Eb/No) and forward error correction (FEC) parameter for determining operational performance of link

4 Analyse properties of geostationary satellites

4.1Calculate look angles for geostationary satellite from any receiving location

Foundation skills

Numeracy: Applies knowledge about space and shape, including angle properties, when analysing variables
Numeracy: Applies knowledge about space and shape, including angle properties, when analysing variables
Numeracy: Determines link budgets by selecting antennae size, power requirements, link availability and bit error rate (BER) by solving complex mathematical formulas
Reading: Interprets complex technical information in a variety of forms and applies the knowledge gained to solve complex problems by making informed judgements and assumptions
Writing: Uses clear, specific and industry related terminology to prepare detailed reports containing recommendations for relevant personnel
Planning and organising: Analyses data and seeks feedback to improve plans and processes
Planning and organising: Makes high impact decisions in a complex and diverse environment, using input from a range of sources
Planning and organising: Identifies key factors that impact on decisions and their outcomes, drawing on experience, competing priorities and decision-making strategies where appropriate
Planning and organising: Operates from a broad conceptual plan, developing the operational detail in stages, regularly reviewing priorities and performance during implementation, and identifying and addressing issues as the work progresses
Problem solving: Addresses complex problems involving multiple variables, using formal analytical, lateral thinking techniques, experience and knowledge to focus on the root cause
Self-management: Takes responsibility for high impact decisions in complex situations involving many variables and constraints

Questions about assessing ICTRFN806

What does an assessment tool for ICTRFN806 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for ICTRFN806 needs to address all 40 unit components: 4 elements with 12 performance criteria, 4 performance evidence requirements, 13 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for ICTRFN806?

Auditori pulls the current release of ICTRFN806 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for ICTRFN806 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing ICTRFN806 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of ICTRFN806, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
