Application
This unit of competency specifies the outcomes required to conduct advanced global navigation satellite system (GNSS) control surveys using GNSS equipment and suitable software to communicate with GNSS receivers. The unit covers project managing surveying activities, including planning collection methodologies and allocating resources and work tasks in a team environment. The unit also covers analysing existing survey control data and networks to identify non-conformities and the need for additional controls, and implementing a network of points for controlling horizontal and vertical positions. The unit requires the ability to program, calibrate and operate GNSS equipment, relate surveying data to a reference system, and identify and resolve discrepancies with the reference system.
The unit supports those who work in a technical management role in a surveying team.
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
