Precision State Estimation for Autonomous Flight
Modern aerospace platforms generate terabytes of data from diverse sensors. AeroVance's Navigation & Sensor Fusion division specializes in synthesizing this multi-modal data into a single, high-fidelity truth. Our algorithms ensure that drones, missiles, satellites, and crewed vehicles maintain precise situational awareness even in GPS-denied or contested environments.
We utilize industry-standard and proprietary Extended Kalman Filters (EKF), Unscented Kalman Filters (UKF), and Particle Filters to manage uncertainty, reduce drift, and optimize trajectory accuracy.
Tight-Coupling Architecture
Unlike loose-coupling methods that fuse position fixes, AeroVance implements deep tight-coupling. Raw sensor measurements (Doppler, Code Phase, Carrier Phase) are fed directly into the state estimator alongside IMU data.
This approach allows the system to maintain navigation continuity even when satellite signals are below tracking thresholds, significantly improving resilience against jamming and spoofing.
Integrated Sensor Modalities
Inertial Navigation (INS)
Ring Laser Gyro (RLG) and Fiber Optic Gyro (FOG) IMUs ranging from tactical-grade to navigation-grade. Integrated strapdown algorithms for drift correction.
GNSS / GNSS-Inertial
Multi-constellation support (GPS, GLONASS, Galileo, BeiDou) with anti-spoofing AI. Precise Point Positioning (PPP) and Real-Time Kinematic (RTK) capabilities.
Radar & LiDAR
Fusion of terrain-referenced navigation (TRN), Doppler velocity logs, and 3D LiDAR point clouds for high-fidelity SLAM in urban canyons and indoors.
Computer Vision
Feature-based visual odometry and optical flow sensors. Deep learning object detection pipelines fused with state estimation for autonomous obstacle avoidance.
Star / Celestial
Optical star trackers and celestial navigation modules for deep-space and long-endurance missions where GNSS is unavailable.
Magnetic / Terrain
Multi-frequency magnetometers and digital elevation model (DEM) matching for all-weather terrain contour matching (TERCOM).
