The 23rd International Flight Inspection Symposium (IFIS) will bring together aviation experts in San Salvador from 4 to 8 May 2026. Rohde & Schwarz will be on site demonstrating its latest test and measurement solutions for ground?based navigation aids, tailored to today’s rising traffic volumes and stricter safety demands.
IFIS 2026 features a five?day program that blends technical sessions, hands?on workshops, and live flight validation activities.
Rohde & Schwarz will contribute to the technical program with a presentation on Challenges for UAV Operations in RF?Dense Aerodrome Environments, highlighting how unmanned systems can operate reliably in complex radio?frequency landscapes around modern airports.
The aviation sector is grappling with higher air traffic density, rapid technological change, and evolving security requirements. In this environment, operators need test equipment that delivers laboratory?grade precision without breaking down in the harsh conditions of an airport runway or remote navaid site.
At the Rohde & Schwarz booth, visitors will see the R&S EVSD1000 VHF/UHF Nav/Drone Analyzer, a compact solution designed to perform ILS, GBAS, and VOR measurements in line with ICAO Doc 8071 and ICAO Annex 10.
The receiver combines lab?level accuracy, air?to?ground Wi?Fi datalinks, and gapless measurement capability with improved location accuracy during flight inspections. Crucially, the device can be mounted on a drone, cutting the need for manned flight?inspection sorties and reducing operational costs over time.
For airlines, airport operators, and navigation service providers, Rohde & Schwarz offers a robust way to certify and maintain ground?based navigation aids under today’s demanding conditions. By integrating high measurement accuracy, straightforward operation, and field?ready durability, the company is helping the industry keep pace with continued growth and higher safety expectations.
