introduction
Introduction
  • Problem:
    • Coordinating airborne Unmanned Aerial Vehicles (UAVs) to intercept and track a Target Of Interest (TOI) in an urban environment is time consuming and labor intensive.

mission statement
Mission Statement
  • The UCATS is a command and control system designed to:
    • Route UAVs to TOIs
    • Monitor the UAV location
    • Redirect the UAVs when new tasking arrives
  • Primary Mission:
    • To recommend which airborne UAVs should track TOIs
    • Direct the UAVs on a TOI intercept course
    • Monitor UAV position
    • Redirect the UAVs as new TOI tasking becomes available.
  • Goal:
    • Reduce manpower from 5 people to 1
    • Reduce time required to calculate TOI intercept from 45 minutes to 5 minutes

ucats instantiated architecture 1
UCATS Instantiated Architecture [1]
  • Communication Module
    • Most trade-off and most affected by technology upgrades
    • Key technology considerations:
      • Encryption technology
      • Satellite Communication (SATCOM) radios
      • Bandwidth
    • Key design Considerations
      • UAVs use both SATCOM and Line-of-Sight (LOS) Radio
      • Buildings in urban areas will restrict LOS comms
  • Processors – One main UCATS processor(s)
      • Simpler and more reliable than processor for each functionality
  • Software Architecture:
    • Integral part of UCATS design
    • HCI Design part of usability assessment
    • Algorithm part of prototype

Future UCATS Work

Conduct detailed design of UCATS hardware:

Select the specific UCATS Components

Determine if UCATS should include communication UAV

May get technology improvement with SATCOM

Customer may decide UAV costs to expensive and not require continuous stream of surveillance video

Conduct detailed design of software:

Key aspect of SW development involves HCI design
