Design of SINS/LDV/OD Autonomous Positioning System Based on Carrier Constraint
Received date: 2018-10-17
Online published: 2025-05-12
Based on the theory of SINS/LDV/OD integrated navigation system, the LDV/SINS and OD/SINS sub filters of the Federated Kalman filter is designed, and the main filter in autonomous positioning system is devised.This is focused on the requirements for precision and reliability of positioning and orientation system in missile launching vehicle.A fault-tolerant scheme for autonomous positioning system is designed based on the fault characteristics of sub filters.After the test of 50 km car experiment, the longitude error of the self-localization result is within 20 m, the latitude error within 20 m, and the height error within 10 m.The design is effective and can meet the actual operational requirements.
