Sso Ephemeris Form

This Web form is a user interface to the VO-compliant Web service Miriade, which allows one to compute various positional ephemeris of Solar system objects: planets, the major natural satellites, asteroids and comets. This Web form is a demonstrator of interoperability between a client (the form) and a remote server which actually compute the ephemeris. Thanks to the data format (VOTable) and the SAMP protocole, this demonstrator shows how easy one can query ephemeris and broadcast the result to its prefered application. Read more...

To compute an ephemeris, fill the form below and click on the button "Compute Ephemeris". The result will be posted below the form. To know how to fill the requested inputs, click on the arrow on the right of inputs, and follow the guide.

The ephemeris query form is still in development and will be fully available in 2012.
