Feasible study on establishment of a GPS reference station

Permanent GPS network provides an excellent frame of reference for geodetic positioning in Malaysia and several kinematic applications have been carried out by post-processing the data. This research study investigates on the feasibility of having a permanent and reliable GPS control station in UiTM. To achieve this purpose, a minimum construction is carried out by erecting a concrete monument of the reference station on the roof top of a building in UiTM Shah Alam. The observation technique is conducted in Static Mode continuously throughout the period using a Leica SR520 GPS instrument and processed using the SKI-Pro software. To relate with the national coordinate system, additional data were acquired from JUPEM. All the processed results were analyzed and compared with positions from MyRTKnet. The analysis shown that the coordinates derived for this station is consistent within acceptable tolerance. With the ability to view sufficient number of needed satellites twenty four hours a day, a secure location for the instruments, the chosen location is feasible as a control station. It will be used as a reference station by users for their academic purpose and research study. Furthermore, it is hoped that this reference station be a stepping stone for future development of an independent Real Time Kinematic GPS (RTK-GPS) which currently has already been implemented by JUPEM. In addition, the data from the observation will be provided to students through the internet.
