This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard has been developed for the surveying occupational area and is intended for persons who aim to achieve career advancement within social and economic transformation by gaining surveying skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to determine the position of survey points using the Global Positioning System (GPS).

A qualifying learner credited with this unit standard will be able to:
  • Display a knowledge of Global Positing Systems GPS positioning principles and procedures
  • Prepare for positioning of survey points by GPS
  • Determine the preliminary position of survey points.
  • Complete the work sequence in accordance with survey standards.
