We report on the orbits of the small, inner Saturnian satellites, either recovered or newly discovered in recent Cassini imaging observations. The orbits presented here reflect improvements over our previously published values in that the time base of Cassini observations has been extended, and numerical orbital integrations have been performed in those cases in which simple precessing elliptical, inclined orbit solutions were found to be inadequate. Using combined Cassini and Voyager… 
Occultation Observations of Saturn's B Ring and Cassini Division
The outer edge of Saturn's B ring is strongly affected by the nearby 2:1 inner Lindblad resonance of Mimas and is distorted approximately into a centered elliptical shape, which at the time of the
Saturn's inner satellites : orbits, masses and the chaotic motion of Atlas from new Cassini imaging observations
We present numerically-derived orbits and mass estimates for the inner Saturnian satellites, Atlas, Prometheus, Pandora, Janus and Epimetheus from a fit to 2580 new Cassini ISS astrometric
Cratering and age of the small Saturnian satellites
Context. The small (≤135 km mean radius) satellites of Saturn are closely related to its rings and together they constitute a complex dynamical system where formation and destruction mechanisms
Revised orbits of Saturn's small inner satellites
We have updated the orbits of the small inner Saturnian satellites using additional Cassini imaging observations through 2007 March. Statistically significant changes from previously published values
Cassini spectra and photometry 0.25–5.1 μm of the small inner satellites of Saturn
Abstract The nominal tour of the Cassini mission enabled the first spectra and solar phase curves of the small inner satellites of Saturn. We present spectra from the Visual Infrared Mapping
Saturn's Small Inner Satellites: Clues to Their Origins
TLDR
Cassini images of Saturn's small inner satellites have yielded their sizes, shapes, and in some cases, topographies and mean densities, and numerical N-body simulations of accretionary growth have provided clues to their internal structures and origins.
Formation of the G-ring arc
Since 2004, the images obtained by Cassini spacecraft's on-board cameras have revealed the existence of several small satellites in the Saturn system. Some of these small satellites are embedded in
Noncircular features in Saturn’s rings II: The C ring
Abstract We present a comprehensive survey of sharp-edged features in Saturn’s C ring, using data from radio and stellar occultation experiments carried out by the Cassini spacecraft over a period of
Time Variability in the Outer Edge of Saturn's A-Ring Revealed by Cassini Imaging
We examine the outer edge of Saturn's A-ring, whose shape is strongly influenced by the co-orbital satellites Janus and Epimetheus, during the period from day 2005-121 to day 2009-036. Twenty-four
The shape of Saturn’s Huygens ringlet viewed by Cassini ISS
Abstract A new model for the shape of the prominent eccentric ringlet in the gap exterior to Saturn’s B ring is developed based on Cassini imaging observations taken over about 8 years. Unlike

HST Observations of Saturnian Satellites during the 1995 Ring Plane Crossings
Abstract In May, August, and November 1995, Hubble Space Telescope (HST) observations during Saturn's ring-plane crossings allowed us to view saturnian satellites normally hidden to Earth-based
New observations of Saturn's coorbital satellites
Abstract We present observations of the Saturnian coorbital satellites, Janus and Epimetheus, obtained with the Caltech Cassegrain infrared camera at the Palomar Hale telescope in July and August
Cassini Discovers a Kinematic Spiral Ring Around Saturn
TLDR
New Cassini observations show that these strands, initially interpreted as concentric ring segments, are in fact connected and form a single one-arm trailing spiral winding at least three times around Saturn.
Astrometry of Saturn’s Satellites from the Hubble Space Telescope WFPC2
Highly accurate astrometric positions of 14 of Saturn's satellites have been obtained from 444 Hubble Space Telescope images taken with the Wide Field Planetary Camera 2 (WFPC2) between 1996 and

Abstract We have obtained numerically integrated orbits for Saturn's coorbital satellites, Janus and Epimetheus, together with Saturn's F-ring shepherding satellites, Prometheus and Pandora. The
Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites
TLDR
Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings.
Evidence for the existence of additional small satellites of Saturn
Abstract Imaging data are presented which indicate that small satellites exist in the Saturnian system in addition to those whose orbits had been firmly established by the time of the Voyager 2
Further Evidence for the Existence of Additional Small Satellites of Saturn
Abstract There is substantial evidence for the existence of small satellites in the saturnian system in addition to those with well-determined orbits derived from ground-based and Voyager
