摘要	Tightly integrated navigation based on an extended Kalman filter (EKF) has become ubiquitous across domains such as autonomous driving. The accuracy of the innovation matrix plays a crucial role in the filtering process. However, the variance in data quality across different satellites due to various errors, as well as the nonlinear errors introduced by the linearization of the measurement equation and the errors resulting from the Gaussian noise assumption, can lead to inaccuracies in the innovation matrix. We address these aforementioned issues and propose an adaptive solution relying on Resnet-efficient multihead self-attention (Res-EMSA) to adjust the innovation matrix. Specifically, the network model extracts the features of the global navigation satellite system (GNSS) and inertial navigation system (INS) data through the residual network, and then the features are fused with different weights. After that, the EMSA network is utilized for feature mapping, and ultimately, the fully connected layer is used to perform weight matrix regression. Experimental results reveal that the Res-EMSA model exhibits a significant enhancement in positioning accuracy, with a 39% increase compared to the traditional EKF model.
