• Improper planning reduces reliability
and availability
• Up to 30% of all failed UAS missions
are due to comms failure
• Dynamic problem with many
variables
• Different communications systems
expose different problems
Evaluating mission success
• As UAS numbers increase they need
to be easier to operate
• Models need to be flexible and
validated
• Need to be able to convey complex
concepts easily
• A single route is not the best result

Issue
Loss Of Signal During Aircraft Ground Taxi to End of Runway
Loss of Signal at Northeast Part of Flightpath; Particularly in the Turn and At Max Altitude of 50Kft
Fixes
Moved Receive Antenna Location On Building Roof – Fixed Taxi Issue
Adding Low Noise Amplifier to the Receive Antenna Produced Much Improved Signal at Northeast Part of Flightpath
Narrowed Bandwidth on Receiver to Improve Signal-to-Noise Ratio
Downlink Communication Issues
