Rohde & Schwarz will launch its R&S EVSD1000 VHF/UHF nav/drone analyzer at Airspace World 2023 in Geneva from March 8 to 10, 2023. The analyzer provides highly accurate and efficient drone inspection of terrestrial navigation and communications systems along with outstanding accuracy and the measurement repeatability customers need.
Civil aviation requires accurate and reliable navigation systems for optimizing air traffic control (ATC) 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.
The VHF/UHF nav/drone analyzer is a signal level and modulation analyzer for medium-sized drones. It is the only instrument that combines measurements of instrument landing systems (ILS), ground-based augmentation systems (GBAS) and VHF omnirange (VOR) ground stations in a single box. The mechanical and electrical design is optimized for drone based, real-time measurements of terrestrial navigation systems with up to 100 measurement data sets per second.
The analyzer provides high-precision signal analysis in the frequency range from 70 MHz to 410 MHz, a critical requirement for drone based terrestrial navigation signal measurement systems. This also includes the needed measurement repeatibility to ensure that results from drone measurements can be compared to flight and to ground inspections in line with ICAO standards.
