Assessment of Real Time Kinematic Global Positioning System (RTK GPS) Application for Simulation of Building Monitoring

Nowadays, Global Positioning System (GPS) is the most important technological innovation in the field of deformation studies because there are more large and tall buildings than in the past. These building are being designed to be much more flexible and to resist extensive damage from changes in temperature, severe wind gusts and earthquakes. Structural engineer require the best, precise and reliable instrument to resolve their concern about building movement. Thus, various type of Real Time Kinematic GPS (RTK GPS) surveying method such as Single-Based and Network-Based RTK GPS need to be assessed in order to determine the precision and capability of detecting small and large movement of building. This research aims to check the accuracy and capability of Single-Based RTK GPS surveying method to detect small and large movement by using building monitoring simulation. Several GPS points have been established around Universiti Teknologi PETRONAS (UTP) in order to assess the precision, capability and communication of Single-Based RTK GPS. The result collected determined the 100% communication signal between base and rover receiver within 2 kilometer. Besides that, RTK GPS surveying method also produced very high precision and capable to detect small and large movement up to centimeter level accuracy
