Abstract	Infrastructure development requires significant changes and transformation in the Geomatics field for the upcoming decade. The use of new technology in Geomatics and surveying is essential and can be leveraged in many survey applications that will help on building the nation towards a sustainable future. In the last 5 years, GNSS technology has been widely used and practiced to replace total station for survey work. Main factors that contribute to these business changes are the availability of much cheaper equipment with good technical capability in the market that helps the surveyor to perform their work faster and more efficiently. Global navigation satellite system services for accurate positioning has also rapidly increased and provides many options and solutions for the industry player or surveyor to choose. Combination of multiple global navigation satellite system providers such as GPS, GALILEO, GLONASS and BeiDOU have developed good satellite networks and increased numbers of available satellites for observation that improve absolute position accuracy. CHC i70 is among the best selling GNSS model on the market right now. The receiver can receive signal from GPS, GALILEO, GLONASS and BeiDOU simultaneously. This study will outline and focus on the capability of the RTK-Based method (30 second to 1 minute observation period) using CHC i70 instrument in high-precision measurement work. The research was done using the GPS calibration test site at Politeknik Sultan Haji Ahmad Shah (POLISAS) and was also practiced in the actual work for establishment of Temporary Bench Mark (TBM) along Jalan Melor to Ketereh, Kelantan. The result of the study found that RTK-Based method can meet the precision work that is permitted under 2cm accuracy. Studies show that the method of using RTK- Based is suitable for high precision work and improves the measurement time and work duration at field. (As Provided).
