PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

             Automatic Gain Control

This dataset (HUYGENS_AGC) is a measure of the signal strength of the Huygens radio signal (Channel B) as measured on the Cassini spacecraft, and is of interest for understanding the Huygens dynamics during descent and at impact, as well as in radio propagation studies.



We are proposing that this product be included in the extras directory. We will link it from there.






Huygens PTA Gain Pattern Channel B



           The color code denotes the gain of the probe antenna in decibels with respect to isotropic (i.e. gain in dBi).

           Elevation = 0 is vertically upwards, 90 degrees is horizontal.
           Azimuth= 0 is in the +y direction, 270 degrees is in the -z direction (boresight of the DISR camera). See also figure 4 of Dzierma et al., 2007
