Photopolarimeter System (PPS)

NSSDC ID: 1977-084A-11
Mission Name: Voyager 1
Principal Investigator: Dr. Arthur Lonne Lane

Description

This experiment consisted of an 8-in. (20 cm) f/1.1 telescope that could send its observations through a polarizer and a filter for one of eight bands in the 2200- to 7300-A spectral region, then on to a photomultipler tube. By study of these emission intensity data, information on surface texture and composition of both planets (Jupiter and Saturn) could be obtained, along with information on size distribution and composition of the rings of Saturn and information on atmospheric scattering properties and density for both planets. Molecular scale heights for both planets could also be determined from these data.
