Hi everyone,
We’ve been tackling a challenging issue and are seeking assistance from the community. Our project revolves around solving a vision-aided positioning problem for non-GPS navigation. We’ve made significant progress on the vision component, successfully extracting (longitude, latitude) coordinates from camera frames matched with a reference map. Now, our aim is to replace the conventional GPS receiver with our vision system.
Initially, we’re attempting to relay real GPS messages from a Ublox M8N device to the Cube Orange through the GPS1 port. If this integration works smoothly, we plan to gradually transition to using vision-derived coordinates.
However, we’ve encountered a hurdle in our efforts. While the quadcopter remains stationary on the ground, the Cube Orange reliably receives GPS coordinates, allowing us to arm it in Loiter mode without issues. However, during flight, after a short duration, we experience GPS glitches, resulting in a drone crash.
We’re eager to share both the BIN log file and our Python code for relaying GPS data to the Cube. We’re hopeful that by collaborating with the community, we can pinpoint the missing piece of the puzzle.
