This article describes how FreeScopes Basic III and IV enhance ATSEP training across Communication, Navigation, and Surveillance for Levels 2–5 in ICAO taxonomy.
Air Traffic Safety Electronics Personnel (ATSEP) training requires tools that address a diverse range of competencies in Communication (COM), Navigation (NAV), and Surveillance (SUR) systems. To meet these requirements effectively, training must integrate theoretical knowledge with hands-on experiences. FreeScopes Basic III and IV are designed to address this need, providing advanced tools for trainees to explore signal processing, antenna behavior, and system optimization.
These solutions are versatile, supporting training at various taxonomy levels, from foundational understanding (Level 2: Comprehension) to advanced troubleshooting and optimization (Levels 3–5). This blog explores how FreeScopes Basic III and IV enhance ATSEP training across multiple domains.

At Level 4 (Analysis) and Level 5 (Synthesis and Evaluation), FreeScopes modules support:
- Advanced troubleshooting, such as diagnosing signal interference or optimizing radar parameters.
- System-wide evaluations, including link budget analysis and propagation delay optimization, to enhance overall performance.
Example Use Cases for Training
Scenario 1: Optimizing Radar Performance
Using FreeScopes Basic III, trainees adjust PRF settings and apply noise filtering to improve target detection. With Basic IV, they analyze radar antenna patterns and propagation delay to optimize coverage and accuracy.
Scenario 2: Diagnosing Communication Issues
A trainee uses FreeScopes Basic III to analyze VHF signal modulation and identify noise interference. They then leverage Basic IV to examine antenna alignment and resolve an impedance mismatch affecting transmission quality.
Scenario 3: Enhancing Navigation System Accuracy
Trainees explore GNSS signal propagation using Basic IV, analyzing multipath effects and applying polarization adjustments to improve system reliability.
Competency-based Training Across Multiple Taxonomy Levels
FreeScopes Basic III and IV are transformative tools for ATSEP training, addressing the diverse requirements of communication, navigation, and surveillance systems. Their versatility supports ICAO’s competency-based training model across multiple taxonomy levels, from building foundational understanding (Level 2) to mastering advanced analytical and optimization tasks (Levels 3–5).
