WGS-84 Surveying
The Survey Section of the Aeronautical Information Services Department has the infrastructure, equipment and expertise to provide full GPS (WGS-84) Airport Surveys
This service is conducted in accordance with the standards of both the ICAO Doc 9674 and the United States National Geospatial Intelligence Agency’s (NGA) Terminal Aviation GNSS Geodetic Programme. The Global Positioning System (GPS) is a navigational technology based on constellations of 24 satellites orbiting the earth at an altitude of approximately 20 000 kms. This system is capable of sub-centimetre accuracy worldwide. WGS-84 supports RNAV/GNSS.
Abilities
The survey team operates throughout the African continent and can be deployed globally. The equipment employed is the latest and top of the range, capable of establishing geodetic connections for those countries which do not have the WGS-84 system as their national network. All team members are Registered Surveyors and are certified in Practical Airport Radiotelephony & Airside Competency as well as holding Airside Vehicle Operators Permits.
