DE200 Ephemeries
================

The DE200 ephemeris are available from the JPL via Internet:

    http://ssd.jpl.nasa.gov/

The "README" for the ephemeris package can be found at:

    http://ssd.jpl.nasa.gov/iau-comm4/README


There are two versions available:

    a binary for unix and
    an ascii for other operating systems.

Additionally there is a program "asc2eph.f" for converting the
the ascii files into the binary format. For the use in the
Bernese GPS Software the binary format is required!

Some UNIX systems (like LINUX or IRIX) do not read the binaries
from JPL correctly. For those systems the conversion from ascii
to binary is also necessary.


A documentation for the DE200 ephemeris and for other tools
(like merging the files) are also given on the web-page.
