San Salvador hosts IFIS 2026, a five‑day program that combines technical sessions, workshops and flight validation activities. Rohde & Schwarz will take part in the conference’s technical sessions with a presentation on the topic Challenges for UAV Operations in RF Dense Aerodrome Environments.
The aviation sector today faces increasing air traffic density, rapid technological advancements and heightened security concerns. Operators need test equipment that delivers laboratory level precision while tolerating the harsh environment of an airport runway or a remote navigation site.
Among the exhibits at the Rohde & Schwarz booth is the R&S EVSD1000 VHF/UHF Nav/Drone Analyzer, designed to conduct ILS, GBAS and VOR measurements in line with ICAO Doc 8071 and ICAO Annex 10. The receiver delivers laboratory precision, supports an air to ground Wi‑Fi datalink and gapless measurements with improved location accuracy during flight inspections. Customers benefit from a device that can be mounted on a drone, reducing the need for manned flights and lowering operational expenses.
Rohde & Schwarz gives airlines, airport operators and navigation service providers a reliable way to certify and maintain ground‑based aids under today’s demanding conditions. By combining high measurement accuracy, easy operation and durability, Rohde & Schwarz aims to help the industry keep pace with growth.
