Tenders Are Invited For Domain Nonlinear State Estimation For Autonomous Systems Using Unscented Kalman Filtering

Tenders are invited for NAVISP-EL1-127-Cross-Domain Nonlinear State Estimation for Autonomous Systems Using Unscented Kalman Filtering- Expro plus Tender Action Number: 1-13385 Activity Number: 1000046050 Clarification Request Deadline 29/05/2026 13:00 CET Closing Date Extension Request Deadline 29/05/2026 13:00 CET Announcement Date 26/03/2026 Last Update On 01/05/2026 10:43 CET Update Reason Tender Action Issued This activity aims to develop a modular Unscented Kalman Filter (UKF)-based state estimation framework for autonomous systems operating in GNSS-challenged environments. It will enable robust multi-sensor fusion using GNSS, IMU, LiDAR, and vision data without relying on linearization, improving accuracy over traditional EKF approaches. The framework will incorporate adaptive noise modeling andadvanced unscented transformations for resilience under sensor degradation and dynamic conditions. A prototype will be designed, tested in hardware-in-the-loop setups, and validated through field trials on ground vehicles or UAVs. Comparative benchmarks against EKF and other filters will be performed, and a roadmap for integration into autonomy stacks will be delivered.
