This　paper　presents　an　innovative　integrated　sensor　that　combines　GNSS　and　a　low-cost　accelerometer　for　bridge　health　monitoring.　GNSS　and　accelerometers　are　both　significant　and　effective　sensors　for　structural　monitoring,　but　they　each　have　limitations.　The　sampling　rate　of　GNSS　data　is　relatively　low,　making　it　challenging　to　capture　high-frequency　vibrations,　while　accelerometers　struggle　with　low-frequency　signals　and　are　susceptible　to　environmental　changes.　Additionally,　GNSS　receivers　and　accelerometers　are　often　installed　separately,　leading　to　challenges　in　data　fusion　processing　due　to　differing　temporal　and　geospatial　references.　The　proposed　integrated　sensor　addresses　these　issues　by　synchronizing　GNSS　and　an　accelerometer’s　time　and　geospatial　coordinate　reference.　This　allows　for　a　more　accurate　and　reliable　deformation　and　vibration　measurement　for　bridge　monitoring.　The　performance　of　the　new　sensor　was　assessed　using　a　high-quality/cost　Leica　GM30　GNSS　receiver　and　a　Sherborne　A545　accelerometer.　Experiments　conducted　on　the　Wilford　suspension　bridge　demonstrate　the　effectiveness　of　this　innovative　integrated　sensor　in　measuring　deformation　and　vibration　for　bridge　health　monitoring.　The　limitation　of　the　low-cost　MEMS　(Micro　Electromechanical　System)　accelerometer　for　the　weak　motion　frequency　detection　is　also　pointed　out.　©　2024　by　the　authors.
