[AstroPy] satellite-centered ephemeris

I would like to calculate RA and Dec of solar system objects at the
position of the Herschel satellite. This can be done in the on-line JPL
Horizons system setting the observer to @herschel, however I would like
to calculate the coordinates from the orbital elements of Herschel and
the object at different times. I have checked that pyEphem Observer
object supports positions on Earth's surface; is there any available
package where I can use the orbital elements of a satellite to define
the observer frame?
