Visible　light　positioning　(VLP)　is　one　of　the　effective　solutions　for　low-cost　and　high-precision　indoor　positioning　due　to　its　advantages　of　low　cost,　high　energy　efficiency,　and　immunity　from　radio　frequency　induced　electromagnetic　interference.　However,　severe　performance　limitations　in　occluded　environments　present　a　major　challenge　for　the　development　of　VLP.　We　propose　a　non-line-of-sight　(NLOS)　VLP　system　based　on　a　multipixel　photon　counter　(MPPC)　to　solve　the　problem　of　obstructed　line-of-sight　(LOS)　paths.　MPPC　consists　of　multiple　avalanche　photodiodes　operating　in　Geiger　mode,　which　has　very　high　sensitivity,　excellent　photon　counting　capability　and　can　perform　detection　of　very　weak　light　at　photon　counting　levels.　It　can　effectively　improve　the　recognition　and　detection　of　signals　in　NLOS　environments.　Using　the　NLOS　channel　model,　we　innovatively　propose　a　NLOS-MPPC-VLP　positioning　theory,　which　utilizes　the　NLOS　optical　signals　received　by　the　MPPC　to　construct　the　relationship　between　the　received　signal　strength　and　the　distance　from　the　MPPC　to　the　virtual　images　of　the　light　emitting　diode　(LED).　Through　this　theory,　the　trilateration　algorithm　is　used　to　calculate　the　position　of　the　receiver.　The　experimental　results　show　that　the　average　positioning　errors　for　the　proposed　system　are　8.77　and　10.15　cm　for　70　and　100-cm　MPPC　heights,　respectively.　©　2014　IEEE.
