Notice of RetractionArchitecture and performance for MEMS-IMU aided GNSS tracking loops based on Fuzzy model

Abstract

Proposed a MEMS-IMU aided GNSS tracking loops within an ultra-tightly integration architecture based on a Fuzzy model. The IMU data provide LOS Doppler information to the GNSS tracking loops based Fuzzy logic controller. The performances of the model were simulated test and compared to the conventional tracking loops. The results show the proposed model could reduce carrier phase tracking loops bandwidth to 10Hz and improve the noise rejection .The improvement offer the ability of faster tracking of the carrier phase and robustness improvements to the GNSS receiver and integration of MEMS IMU/GNSS system.
