OiSAM-FGO: an efficient factor graph optimization algorithm for GNSS/INS integrated navigation system

Abstract In recent years, the Factor Graph Optimization (FGO) algorithm has gained a great attention in the field of integrated navigation owing to its better positioning performance than the traditional filter-based approaches. However, the practical application of the FGO algorithm remains challen...
