A Novel INS/USBL Integrated Navigation Scheme Via Factor Graph Optimization
IEEE Transactions on Vehicular Technology, 2022Factor graph optimization (FGO) is a well-known approach in the robotics field. Due to multiple iterations and application of large amounts of data, it usually could superior performance than the Kalman Filter (KF) under complex scenarios. However, it is
