Hi,
my team is currently building a fixed wing drone. We are at the moment undecided whether we should use a classic RC for manual control or whether a joystick setup is sufficient for our use-case. For our final use-case, the control will be “very assisted” so that the operator has an easy as possilbe flying experience. We will probably get a Holybro Pixhawk 6C and a RFDesign UAV RFD868x Telemetry Antenna (2 to 200 kbps).
In the PX4 and the QGroundControl documentation it just says that a “reliable high bandwidth telemetry channel” is required. Other limitations are not mentioned.
My questions:
- How much is “high bandwidth”?
- Can I just calculate the necessary bandwidth by multiplying MAVLink message size with frequency or would I be missing something? I mean there a lots of other messages going through the telemetry channel as well.
- Are there any experiences concerning latency? It is not mentioned anywhere so I just assumed it is not an issue?
- Does anybody has experiences with manual control over telemetry for fast moving drones like copters or fixed wing?
We would prefer to just use the joystick setup, as we have the telemetry antenna anyway, but safe control is ofc a priority.
Thank you very much and greetings from Athens =)
