This guidance note sets out best practice guidelines for surveyors and clients on the use of Global Navigation Satellite Systems (GNSS) in land surveying and mapping.
The guidance provides the surveyor with a set of practical operational guidelines, which can be used when undertaking any survey that includes GNSS techniques. It also provides clients and purchasers of geospatial information generated from a GNSS survey with sufficient information to write a task specific specification for a GNSS survey. This sets out the accuracy requirements, final potential products and scope of work, from which the surveyor can produce an agreed specification and bid for a survey.
This 2nd edition also deals with recent advances in GNSS capabilities such as commercially available RTK systems, SBAS and other augmentation systems, satellite constellation and its effects on precision and the effects of factors such as the troposphere and tidal loading.
