​Cognizant of the fact that Earth gravity is a key element affecting the accuracy of elevation calculations, GCS has adopted a plan for developing a national gravity network for the kingdom of Saudi Arabia. ​​​
Earth gravity has many applications which include the following:
  •  Developing the Kingdom's national geoid to make it more accurate.
  • Storm water channelization
  • Correcting setting-out readings
  • Monitoring volcanic activity
The national Earth gravity network has two levels:​
  • ​The absolute gravity stations​
  • The relative gravity stations 

Also available is a calibration service for the relative gravity devices using the baseline for calibration of the gravity devices, which consists of:

  • Number of stations: 14 stations
  • The baseline is located between the cities of Jeddah and Taif.
  • A10 and CG5 devices are used for station monitoring.
  • Network accuracy: better than 10µGal.
