Polar 6 with closed roll-up doors, in the foreground one can see the ASIRAS-antenna. Polar 6's radar system is similar to the one CryoSat is equipped with. Photo: Johannes Käßbohrer, Fielax, Bremerhaven
Research vessel Polar 6 with open roll-up doors, view from below. One can see the laser scanner on the left and the laser altimeter on the right. Photo: Johannes Käßbohrer, Fielax, Bremerhaven
Screen used to control the laser scanner Ð all components working well. Photo: Veit Helm, Alfred Wegener Institute
ASIRAS in operation. Raw echoes can be seen on the screen which gives operators in flight information on the penetration depth, power response and the ability to steer and control the re-tracker window. Photo: Veit Helm, Alfred Wegener Institute
Jack Beardsley (University of Tasmania) undertaking snow/ice sampling in one of a number of snow pits positioned under the flight path of Polar-6. These data assist in the interpretation of the snow accumulation layers observed by the airborne ASIRAS instrument on Polar-6, Photo: Dan Blight, Australian Antarctic Division (AAD)
University of Tasmania scientist Dr Reed Burgette on a skidoo equipped with Global Positioning System (GPS) equipment Ð this instrument is used to obtain high resolution in situ estimates of surface topography required to validate airborne and satellite data.

Global Positioning System (GPS) and meteorological site deployed to the south west of Law Dome. This site is used to assist in the high accuracy positioning of the AWI Polar-6 aircraft, as well as providing estimates of ice velocity, and atmospheric path delay which is an important variable in the analysis of CryoSat-2 data.

Corner cube reflector placed under the flight path of the AWI Polar-6. The corner cube is used to validate the data from the ASIRAS instrument on Polar-6. Photo: Jack Beardsley, University of Tasmania
Corner Reflector (CR) analysis on raw radar data. The return from the CR is visible as a hyperbola above the snow pack. This data will be used later in the scientific data analysis to gather information on the penetration depth of the KU-Band radar. Photo: Veit Helm, Alfred Wegener Institute
Looking towards the front of Polar-6. During the ferry flights, many boxes with spare parts are carried in this area of the aircraft. Photo: Veit Helm, Alfred Wegener Institute
