Global Navigation Satellite System (GNSS) Awareness


Overview
The purpose of this standard is for candidates to gain the skills required to set out or take surveys using Global Navigation Satellite System (GNSS). The content is relevant to all types of construction including earthworks, roads, houses, buildings, foundations, piles, structural steel, structures and reinforced concrete.

Duration

Minimum 1 day of 6 learning hours

Purpose/scope

The purpose of this standard is for candidates to gain the skills required to set out or take surveys using Global Navigation Satellite System (GNSS). The content is relevant to all types of construction including earthworks, roads, houses, buildings, foundations, piles, structural steel, structures and reinforced concrete.

The scope covers:

  • all about Global Navigation Satellite System (GNSS ) 
  • create a local coordinate system
  • potential sources of error 
  • accuracy
  • connecting with the GNSS rover
  • navigation
  • topographical survey
  • data management
  • on-board functionality
  • select the prism constant.

Occupational relevance

Training delivered against this standard would be relevant to the following occupational group(s):

  • operative and craft
  • supervision
  • management and leadership.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard. However, a working knowledge of 3D coordinate geometry and construction drawings would be beneficial.

Instruction/supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • a train the trainer or instructional techniques course certificate
  • a verifiable CV demonstrating extensive experience as a site engineer across a broad range of construction projects (civils, building etc.) and current experience/CPD in the use of modern topographical equipment 
  • a degree or equivalent qualification in Civil Engineering or Engineering Surveying or similar and have successfully completed training to this standard
  • at least 2 years relevant industrial experience.

Delivery

Delivery may be in an on or off the job environment.

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes. 

The following delivery methods shall be used in the delivery of this standard:

  • classroom 
  • outdoor space to support a range of relevant practical related tasks

This standard is considered to contain 51% or more practical training.

Assessment

For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. 

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the training standard. 

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.

Learning outcomes

The candidate will be able to: Additional guidance to support learning outcome
Use GNSS terminology
