A grounding sinking sensing system of a leveled triangulation point and a benchmark by using a satellite position system is provided to quickly confirm the state of ground subsidence caused by the ground subsidence by wireless transmitting measured data. A grounding sinking sensing system of a leveled triangulation point and a benchmark by using a satellite position system includes a body(10), a measuring unit(20), and a wireless receiver. The body has a support(11), a protecting case(12), a first tube(13), a fluid injection pump(14), a storage tank(15), a GPS unit, a control unit, and a wireless transmitting part. The measuring unit has a slide guide(21) erected on a ground, an outer case(22), a second tube, a fixing unit(24), a control unit, a wireless transmitting part, and a water level measurement instrument which measures a water level of the fluid flowing to the second tube. |
