Civil aviation requires accurate and reliable navigation systems to optimize air traffic control (ATC), ensure basic public safety, and reduce aircraft risks, delays, and costs. Land aviation navigation systems, such as landing systems or in transit navigation systems, require unique testing and measurement capabilities.

The R&S EVSD1000 VHF/UHF navigation/drone analyzer is a signal level and modulation analyzer used for medium-sized drones. It integrates measurement instruments for landing systems (ILS), ground augmentation systems (GBAS), and VHF global (VOR) ground stations within a framework. Its mechanical and electrical design is optimized for real-time measurement of unmanned aerial vehicle based ground navigation systems, with a maximum of 100 sets of data measured per second.

This analyzer provides high-precision signal analysis in the frequency range of 70MHz to 410MHz, which is a key requirement for ground navigation signal measurement systems based on unmanned aerial vehicles. This also includes the required measurement repeatability to ensure that the results of drone measurements can be compared with flight and ground inspections and comply with International Civil Aviation Organization standards.

This analyzer is an ideal choice for ground station testing based on drones around airports. The weight of the instrument is 1.5 kilograms, allowing the use of medium-sized drones to measure the ILS/VOR system in accordance with International Civil Aviation Organization standards.

The benefits obtained by users include: compared to traditional methods such as manual measurement and mast measurement, it reduces runway blockage time, greatly reduces costs, and provides necessary measurement repeatability, measurement accuracy, and GNSS time and position labeling. During drone flight, measurement data is transmitted to the ground computer through a data link, and the analyzer can cache this data internally to ensure that measurement results are not lost in the event of data link loss. This design ensures seamless measurement and rapid report generation.
