The Technical Backbone of Sri Lankan Aviation Safety

Communication Engineering Section – Ratmalana

While Air Traffic Controllers guide aircraft through skyways, Air Traffic Safety Electronics Engineering Officers ensure every radio transmission, radar pulse, instrument landing vector, and network packet functions with zero margin for error.

Operating under CAASL directives and ICAO standards, my expertise spans routine preventive maintenance, high-level troubleshooting of VCSS networks, DVOR/ILS navigation alignment, ADS-B/MSSR surveillance processing, and custom RF alert circuitry.

Zero Downtime

Dual-redundant failsafe architecture design.

Precision Tuning

Strict adherence to ICAO Annex 10 standards.

Secure Links

Hardened microwave backbones & IP-VHF.
