Rohde & Schwarz puts drone analyser into launch mode at Airspace World 2023

At Airspace World 2023, Rohde & Schwarz launches the EVSD1000 VHF/UHF nav/drone-based analyser for efficient air traffic control.
The EVSD1000 VHF/UHF analyser provides accurate and efficient drone inspection of terrestrial navigation and communications systems with accurate, measurement repeatability.
Civil aviation requires accurate and reliable navigation systems for optimising air traffic control and ensuring the essential public safety while mitigating aircraft risks, delays and costs. Terrestrial air navigation systems, such as landing systems or en-route navigation systems require unique test and measurement capabilities, explained Rohde & Schwarz.
The R&S EVSD1000 VHF/UHF nav/drone analyser is a signal level and modulation analyser for medium sized drones. It is claimed to be the only instrument that combines measurements of instrument landing systems (ILS), ground-based augmentation systems (GBAS) and VHF omni-range (VOR) ground stations in a single box.
The mechanical and electrical design is optimised for drone based, real-time measurements of terrestrial navigation systems with up to 100 measurement data sets per second.
The analyzer provides precision signal analysis in the frequency range from 70 to 410MHz, a critical requirement for drone based terrestrial navigation signal measurement systems. This also includes measurement repeatability to ensure that results from drone measurements can be compared to flight and to ground inspections in line with ICAO (International Civil Aviation Organisation) standards.
The analyser is suitable for drone-based ground station testing in the perimeter of an airport. It weighs 1.5kg, sufficient for a medium-sized drone to perform measurements on ILS/VOR systems in line with the ICAO standards.
Customers can benefit from reduced runway blocking times compared to conventional methods (e.g. manual measurements, mast measurements), significantly reducing costs while providing the necessary measurement repeatability, measurement precision and GNSS time and location stamps. While streaming
measurement data during a drone flight via the data link to a PC on the ground, the analyser can buffer this data internally to ensure that no results are lost if the data link is lost. This ensures gapless measurements and easy reporting, said Rohde & Schwarz.
