avo_technical_report.pdf : the main paper in this collection. Gives a little bit historical background. Gives theoretical fundation for the reduction of airborne gravity data with emphasis on stabilized platform systems. And description of some airborne gravity surveys performed by Danish National Space Center Sanders-AirGrav.pdf : the equation here differs slightly from the equations in the above paper mainly due to the Schuler tuning of system fugro.mht : about Fugro airborne gravity system, see also http://www.fugroairborne.com.au/services/gravity/index.html
