Voyager Imaging Science Subsystem (ISS)

The Voyager 1 and 2 spacecrafts each carried two cameras, wide-angle and narrow-angle. An index to the complete technical description of each camera is provided here.

NOTE: See below for memos about the instrument calibration.

Calibration Notes

The standard, published reference for how to calibrate the Voyager images is Danielson et al. 1981:

    Danielson, G. E., P. N. Kupferman, T. V. Johnson, and L. A. Soderblom 1981. Radiometric Performance of the Voyager Cameras. Journal of Geophysical Research, 86, 8683-8689.

It describes the image calibration as understood following the Jupiter encounters.

The Voyager Imaginig Science Subsystem Calibration Report, Benesh and Jepsen, 1978, is now available for general use. It was produced as a JPL document and compiles the results of calibrations and tests performed on the ISS cameras.

Additional memos were distributed to the ISS team prior to the Uranus and Neptune encounters. They have been transcribed here.

Note that these subsequent memos only refer to the Voyager 2 instrument. No re-calibration of the Voyager 1 cameras was ever performed. Nevertheless, it is widely believed that these calibration correction factors are probably reasonable for Voyager 1 images as well.

Plots and information about the various filters, based on the work of Danielson et al. 1981, can be found here.
