Gravimetric geoid model determination for Peninsular Malaysia using least squares modification of stokes / Saiful Aman Hj Sulaiman

Geoid is vital information in the determination of orthometric height via GNSS levelling. Based on the ellipsoidal height observed by GNSS, the accurate orthometricheight can be easily computed by adding precise and accurate geoid model information. This will particularly enable the users to replace...
