A-UAM with UAV-swarms

The integration of positioning/tracking with wireless communications is a feasible approach to achieving unmanned flying in advanced urban air mobility (A-UAM) with autonomous aerial vehicle per se. Thus, our contribution is an air route design to define the traffic of airborne vehicles, and of future fully automated aircraft under the constraints of transmission delay and throughput reliability using machine learning algorithms.

The command-and-control requirement presents an approach to autonomous flying with the assistance of the cellular network that interacts with the aircraft by sending waypoints and velocity commands and receiving position and velocity reports.

Navigation for a UAV-swarm

Challenges

  • Defining connectivity under wireless channel uncertainty 1
  • Distributed positioning/tracking with regards to latency
  • Maintaining the swarm visibility via monitoring
  • Energy efficiency 2

Autonomous flight

Path for UAV-swarm

How robust/reliable are the links: 

1)UAV-to-UAV (formation control)

2)UAV-to-I* (autonomous flying/navigation)

* I: Infrastructure such as Wireless base station/vertiport

Science and technology inquiries

  1. Variance and CRLB performance metrics for latency and positioning
  2. Variance reduction via machine learning
  3. Vertiports networking for the sensing required to track the position of the swarm of UAVs
  4. Air route design under energy consumption and latency constraints
  5. Delay spread is the difference between the propagation delays along two signals 3.  What is the best response to wireless channel delay spread?
