Rings Node Toolkits
This is a set of downloadable software tools developed at the PDS Rings
Node. They enable users to perform a variety of common tasks related to
planning ring observations, analyzing data, or carrying out dynamical
calculations. Tools are generally written in standard C, and are
callable from programs written in either C or FORTRAN-77.
Software toolkits are provided in zip, tar and gzip formats. They have been tested on
workstations running Unix and VMS, but are likely to run on other platforms
with only minimal modifications. They come with complete build instructions

A set of routines for performing calculations related to orbital
motion around an oblate planet. Routines can be used to predict
satellite locations and to calculate arbitrary resonance locations in
A set of routines for manipulating dates and times. It includes
routines for conversions between Universal Time (UTC), Atomic Time
(TAI), and Ephemeris Time (ET). It also performs conversions between
calendar dates and Julian dates, and interprets or formats dates and
times in a variety of styles.
A set of object-oriented routines for manipulating ring occultation data
sets. Tools are provided for reading PDS-labeled data files, applying
geometry and calibration models, filtering and resampling. The toolkit
supports all occultation data archived by the Rings Node.
This toolkit is built upon the PDS's Object Access Library (OAL). You can download
the latest version from the
PDS Central Node
but we recommend you
use version 1.3.1, as optimized by the Rings Node for this toolkit.
