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.
