Airborne gravity gradiometry (AGG) offers an efficient and cost-effective means to acquire high accuracy gravity data that can have wavelengths as short as a couple of hundred meters; however, the long wavelength content in the AGG gravity is limited by the decreasing gravity accuracy with increasing wavelength. Airborne gravimetry (AG) is usually limited to short wavelengths of a few kilometers but its accuracy improves at wavelengths above about ten kilometers. The Full spectrum Falcon simultaneously acquires both Falcon (AGG) data and sGrav (AG) data and thus provides a complete gravity dataset. In this work we demonstrate the technology and data processing schemes to obtain high accuracy gravity over a broad bandwidth.
