Gravity Data

Gravity data observed by JUPEM has two main purposes:

  • To calculate the gravimetric correction in orthometric heighting for the precise leveling network.
  • To calculate the local geoid and produce gravimetric geoid model.

 

  

 

  • The accuracy of First Order Gravity Network is 0.03 mGal. These data are measured using high precision relative gravimeter along the precise leveling route at intervals of 40-50 km for the area that MSL is below 100m and 10-20km for the area that MSL is above 100m. The Network is based on the absolute gravity value of IGSN71 (International Gravity Standardization Net 1971) station at University of Malaya and absolute station at JUPEM Headquarter.
  • The accuracy of Second Order Gravity Network is 0.05 mGal. These data are also measured using high precision relative gravimeter along the precise leveling route at intervals of 1-5 km and referred to First Class Order Gravity Network.
  • The accuracy of Third Order Gravity Network is 0.1 mGal. These data are measured on 5-10 km grid, which referred to Second Order Gravity Network.
