Meeting Notes
Flight Blender Proposal to Join Dronecode Foundation
Presenters
- Chris Clark (InterUSS platform, Linux Foundation)
- Hirishi (Author of Flightblender, OpenSkies)
Presentation Notes
- UTM: Regulation enabling BVLOS flights
- For different functionalities (e.g. Registration, Geo-fencing, etc) different standards are being introduced
- Reason for call: TII was planning to incorporate it into QGC
- Proposal: By having Flight blender included into Dronecode, it can introduce the UTM standards to QGC. Small Working Group (3 ~ 6 months) to try out the integration.
Discussions
- Hirishi was interested in donating the project to Dronecode, and Chris recommended connecting with PX4 team
- When does it become relevant for the mass audience? (Daniel): In the EU the regulation has been passed, for certain areas for BVLOS flights, this will be necessary. It is hard to predict EU’s future decisions.
- What is OpenSky? (Daniel): Open source products, business model is in 1) customization, 2) integration of the system, 3) hosting service. Products are: Flight blender & Front-end.
- Difference with Airmap? (Jay):
- Why don’t you become a UTM provider? (Jay): OpenSkies is quite small. And for now a lot of things (e.g. Business model) is unclear.

Action Items

Proposal: uORB units specification
In the last Community QnA call, daniel raised an initiative to clarify the units in the uORB messages.
Context: Farhang was having trouble migrating from v1.13 to v1.14, for uORB message definitions (e.g. failsafe flags in vehicle status has changed it’s definition). This points to the fact that uORB messages are not documented well inside the .msg file, neither it’s units.
