Understanding UAV Communication - Kalyan Sriram & Vincent Wang

In the past years, increasing complexity in UAV systems has led to more advanced flight controllers and coprocessors, smart sensors and actuators, ground control stations, and the need to reliably communicate between them in real-time. This has led to new technologies such as Cyphal and DroneCAN, as well as new applications for established protocols like MAVLink. However, this has also led to fragmentation in the ecosystem and confusion for both hobbyists and professional adopters. Kalyan Sriram and Vincent Wang compare various protocols, explain their history, and provide guidance to prospective adopters. They share their own experiences - positive and negative - working with these protocols, tools, and hardware. They also introduce newer innovations including Ethernet and LTE and what advances they may provide to the ecosystem. Note: This talk was originally accepted for the Developer Summit 2022 (Austin), but we were unable to present it due to a presenter contracting COVID-19. However, it has been significantly changed and updated based on new development.

What about using zenoh between ground control station and uav? Zenoh has serial link support.
