| Summary: | Geoid determination in Indonesia can be supported by gravity data with high accuracy and density. Based on the geographical conditions of Indonesia, gravity data that meets the specifications for geoid determination can be obtained by airborne gravity measurement. The quality of airborne gravity data must be tested. One simple method to test the quality of airborne gravity data is a cross-over with free-air reduction as the method to change the height of the gravity data. The assumption that there is no masses effect on free-air reduction determines the cross-over analysis result. The results of the cross-over analysis of the airborne gravity data with free-air reduction indicate the existence of outlier in the data. Based on these results, cross-over analysis with free-air reduction can be used for the purposes of detecting outliers in airborne gravity data.
