90 Focus | Radio telemetry data needed varies with a mission’s profile. A short mission can reduce the need for a dynamic data set, as the initial system state has sufficient validity for the entire mission. A longer mission can need more dynamic data to be sent to the aircraft. This airflow data could be added to an unmanned traffic management system in the same way that mapping data has been combined with the position data of UAVs to indicate no-fly zones. Conclusion Developers are looking to combine telemetry and payload feeds in a single, high-bandwidth link that has more spectral efficiency. This is changing the design trade-offs for unmanned systems designers. Being able to use video as part of the telemetry link is increasingly important, and this is driving the use of more advanced radio designs in higher bands as well as beamforming, phased array antennas and mesh networks. New types of data will also have to be carried over these links to boost the performance of unmanned platforms in challenging environments.
