Real-Time 3D Tracking at 80 Hz, 12-20 ms | Marvelmind
Autonomous Drone Flight: What This Demo Shows
This demo shows how accurate the tracking is. A small 30 x 30 cm square keeps its corners and straight edges, and when the view is rotated it stays flat at one height: the accuracy holds in 3D, not only in X-Y. It also shows low latency: the fast blue sensor fusion dots lead at 80 Hz with 12-20 ms latency, and the golden post-processed dots follow.
Key Takeaways
- The 30 x 30 cm square keeps its corners and edges: fine detail and accuracy at 80 Hz
- Rotated view: the square stays flat at one height, so the accuracy holds in 3D
- Blue real-time sensor fusion dots lead, golden post-processed dots follow: 12-20 ms latency
- Accurate position and altitude for PixHawk and DJI indoor drones
Relevant For: Drone Developers, Robotics & Research Teams
Engineers building autonomous indoor drones on PixHawk or DJI, robotics teams and research labs that need fast, low-latency 3D positioning in GPS-denied spaces.
FAQ
Indoor Drone Positioning Technology
The question this demo answers is how fine a detail Marvelmind ultrasound + IMU sensor fusion resolves in the Non-Inverse Architecture (NIA). A 30 x 30 cm square, just under 1 x 1 ft, is small enough that any noise, lag or drift would round its corners and bend its edges. Here the shape is preserved, including both diagonals, so the position is both accurate and consistent. Rotating the view checks the third axis: the square stays a thin flat "pancake" at a constant height from every angle, so the height is as accurate as X and Y. That matters for drones holding altitude indoors. The fast blue dots are the real-time IMU sensor fusion output: 80 Hz updates with 12-20 ms latency. The golden dots that follow are the post-processed track, the most verified layer, which arrives a little later. Seeing both layers together shows that the real-time data is already close to the final verified track. For indoor drones this is the point: a PixHawk drone takes the fused position directly from the mobile beacon, and a DJI drone, whose flight logic runs outside the drone, receives it on the modem side through the RHU. Configuration: 3 Super-Beacons as stationary beacons, 1 Super-Beacon-4 as the mobile beacon, 1 Modem HW v5.1 as the modem and 1 Modem HW v5.1 as the RHU. The feature is enabled by the MMSW0021 license.
