AB: We present a new model of Saturn's bow shock surface. Shock crossings are identified in Cassini magnetic field and plasma data and these are added to the crossings made by Pioneer 11, Voyager 1 and Voyager 2. Using electron densities determined from Langmuir wave observations by the Radio and Plasma Wave System, the solar wind dynamic pressure for the Cassini crossings is estimated. Corrections for the planet's orbital motion and solar wind dynamic pressure variation are made and a conic section is fitted to the crossings using a least squares technique. We examine and discuss the role played by different parameters in determining the size and shape of the Kronian bow shock.
