The　analysis　and　prediction　of　ship　trajectory　based　on　shipping　big　data　is　a　research　hotspot　in　the　shipping　industry,　which　helps　the　port　and　shipping　industry　to　explore　and　discover　new　business　opportunities,　create　new　industrial　value,　and　enhance　the　competitiveness　of　shipping　enterprises.　In　this　paper,　a　ship　trajectory　analysis　and　prediction　system　is　proposed,　and　the　key　technologies　including　standard　trajectory　association　technology,　historical　pattern　mining　technology,　anomaly　detection　technology,　trajectory　analysis　and　prediction　technology,　and　target　entity　relationship　prediction　technology　based　on　deep　learning,　are　analyzed.　©　2023　IEEE.
