With　the　rapid　advancement　of　smart　logistics,　the　demand　for　precise　and　continuous　positioning　has　significantly　increased.　The　integration　of　the　Global　Navigation　Satellite　System　(GNSS)　and　fifth-generation　(5G)　positioning　has　attracted　substantial　attention　due　to　its　promising　capabilities　and　cost-effectiveness.　To　facilitate　continuous　tracking　of　logistics　items　in　both　indoor　and　outdoor　environments,　it　is　essential　to　explore　the　positioning　switchover　strategy.　This　paper　analyzes　the　requirements　of　smart　logistics　and　the　prevalent　positioning　technologies.　Then,　a　GNSS-5G　hybrid　positioning　architecture　is　considered　for　the　logistics　industry.　Furthermore,　an　adaptive　positioning　switchover　strategy　based　on　observable　data　is　proposed,　accompanied　by　a　GNSS-5G　hybrid　positioning　case　to　illustrate　the　positioning　workflow.　Finally,　the　comprehensive　analysis　of　the　positioning　performance　of　GNSS　and　5G　in　various　scenarios　is　conducted,　which　enriches　research　for　future　development　of　positioning　technology.
