Field test
Flying in formation without GPS
Drones that keep their distance to each other by ranging instead of by satellite: notes from a test flight with an IFF Core on every airframe.
A formation needs every aircraft to know where its neighbours are. Without satellite navigation, the IFF Cores measure those distances directly, between the drones.
Distance instead of position
Each drone continuously ranges to its neighbours and corrects its place in the formation. No GNSS signal and no permanent link to a ground station are involved.
What we looked at
- Holding the formation while GNSS is unavailable
- Re-forming after one drone drops out
- A low signature, with no permanent link to command
