Global　Navigation　Satellite　System　(GNSS)　positioning　technology　has　had　widespread　applications　in　the　structural　health　monitoring　as　its　overall　performance　has　improved　significantly　in　the　last　two　decades.　It　is　capable　of　providing　timely　and　accurate　structural　vibration　information　such　as　dynamic　displacements　and　modal　frequencies　at　higher　performance　than　traditional　accelerometers.　The　studies　summarized　in　this　paper　focus　on　the　improvement　of　the　multi-sensors　and　multi-constellation　data　acquisition　techniques,　the　improvement　of　multiple　approaches　for　erroneous　noise　mitigation,　and　innovative　modal　parameter　identification　methods.　We　also　detailed　the　applications　of　GNSS　on　the　deformation　monitoring　for　towers,　chimneys,　tall　buildings,　and　bridges.　With　continuous　enhancements　in　the　algorithm　and　hardware　of　GNSS,　it　is　expected　that　the　application　of　GNSS　technology　can　be　expanded　to　other　fields　such　as　bridge　cable-force　measurements　and　bridge　weight-in-motion　as　well　as　structural　deformation　monitoring.
