What is Sensor Fusion for UAV Navigation in Refueling?
Sensor Fusion for UAV Navigation in Refueling integrates GPS, INS, machine vision, and lidar data using Kalman and particle filters for precise state estimation during autonomous aerial refueling maneuvers.
This subtopic addresses robust navigation in close-proximity operations amid sensor outages and multipath errors. Key methods include Extended Kalman Filters (EKF) for GPS-vision fusion (Mammarella et al., 2008, 100 citations) and combined GPS-machine vision guidance (Campa et al., 2004, 59 citations). Over 10 papers from 2004-2023 focus on probe-drogue and boom refueling systems.
Why It Matters
Sensor fusion enables beyond-visual-range autonomous refueling, extending UAV mission endurance for military surveillance and civilian logistics. Mammarella et al. (2008) demonstrated EKF fusion reducing position errors to under 0.5m in simulations, critical for probe-drogue docking. Fravolini et al. (2004, 89 citations) modeled wake vortex effects, informing control laws that mitigate turbulence-induced instability during approach. Recent reviews like Parry and Hubbard (2023, 22 citations) highlight lidar and stereo vision for probe detection, supporting certification for uncrewed operations.
Key Research Challenges
Wake Vortex Disturbances
Tanker wake vortices cause severe UAV oscillations during final approach. Fravolini et al. (2004, 89 citations) model these nonlinear dynamics, requiring robust fusion to maintain alignment. Control schemes must compensate for 20-30% airspeed drops (Campa et al., 2004).
Sensor Outages in GPS-Denied Zones
Multipath errors and jamming degrade GPS/INS accuracy near refueling baskets. Mammarella et al. (2008) use EKF to fuse vision data, but filter divergence occurs under prolonged outages. Vision-only fallback needs sub-pixel drogue tracking (Li et al., 2012).
High-Precision Relative Pose Estimation
Probe-drogue alignment demands <10cm accuracy at 1m/s closure rates. Lee et al. (2020, 13 citations) apply deep networks for long-range pose but struggle with lighting variance. Stereo fusion with lidar is essential yet computationally intensive (Parry and Hubbard, 2023).
