I have released the Kepler Ephemeris Engine 1.0 for general use. A few people
have been successfully using the 0.2 alpha version for 9 months, and I re-ran
my tests with fresh data from the MPC. I also updated the HTML Help
documentation. All looks well.
Kepler plugs into NOVAS-COM V2 to provide the ephemeris engine needed to get
precise positions for major and minor planets. To get positions for minor
planets, you must supply the orbital elements. Major planet ephemerides are
built in. Kepler does not integrate orbits from one epoch to another, so for
the highest accuracy, you must integrate the orbit prior to setting the
orbital elements properties of Kepler.
Kepler 1.0 is available at the ASCOM web site, in the Downloads section.
The next release of PinPoint (2.1) will contain an enhanced AcquireImages
script that accepts MPC 1-line orbital elements and computes the position of
the minor planet at the time of exposure.
If you're interested in using Kepler, have a look at the MPCEphem.js script
that is included with it. It generates an MPC style ephemeris from a list of
target designations. It includes code to fetch orbital elements from the MPC
via its web interface.
