"Improvements in GPS technology in the 1990’s have expanded the capabilities, and consequently the application, of airborne gravity gradiometry. Gravity gradiometers are preferable in the airborne environment because of the enhanced sensitivity, lower noise levels and spatial resolution in comparison to airborne gravimeters. This technique has been successfully deployed on helicopters, single-engine and multi-engine fixed-wing aircraft. '"`UNIQ--ref-00000000-QINU`"'<br><br> The advantages of the airborne gravity gradiometry surveys are consistent regional coverage in varied topography and rapid acquisition time relative to a [[Ground Gravity Survey|ground gravity survey]]. The areal coverage, desired resolution, station spacing and topography of the field area are a few of the factors to take into account when deciding between a ground or airborne gravity survey. For instance, an airborne survey may provide better coverage and resolution in areas with steep topography than a ground gravity survey because of difficult ground-based access to the stations. '"`UNIQ--ref-00000001-QINU`"' However, a ground gravity survey enables a more detailed characterization and higher resolution of a survey area." cannot be used as a page name in this wiki.
