![[image]](img/tag1.jpg) A light movement of your arm
... and all necessary data are instantly available on your
computer screen. The most complete satellite theories are at your disposal.
The most perfect algorithms and calculating programs are working for you.
Databases, bibliography and ... nothing superfluous.

| INDEPENDENCE AND CONTROL
|
![[image]](img/tag2.jpg) It is necessary to have
several independent models of satellite motion which could
be used to control one another. This allows to have reliable
satellite ephemerides, the most adequate and the most accurate.
| |
| NEW ORBITS
|
![[image]](img/tag3.jpg) New orbital models for
all the new faint satellites of Jupiter, Saturn, Uranus and Neptune
were determined independently from other authors on the basis of all
published observations using numerical integration method applied to
the equations of satellites motions. |
|
| PERFECTION
|
![[image]](img/tag4.jpg) For all other satellites
the most perfect theories and models of motion built by different
authors worldwide have been used. Corresponding ephemerides are available.
| |
| HELP FOR THE OBSERVERS
|
![[image]](img/tag5.jpg) You may enter the results of your
observations for a series of dates in tabular form and you will get deviations
between theory and observations (O-C) for the whole table at once as well as
statistic parameters.

|
| DATA ACCESSIBLE TO EVERYONE
|
![[image]](img/tag6.jpg) This database gathers all available
astrometric data on natural planetary satellites under the auspices of IAU
and is avaialable for all. Please, send your observations in order to help the other
interested astronomers.
