NASA/JPL Horizons API Programming Reference Links
-
To use the programs on this web site requires a PHP-enabled public or private web server on which to run them and an Internet connection to access the NASA/JPL Horizons API server.
-
For PHP astronomy programmers wanting to make customized use of the NASA/JPL Horizons API, these programs may prove useful in accelerating program development around the API.
-
The on-line public web interface to the
Horizons System app can be found at:

-
The on-line manual that explains the symbols and operations of the web interface
to the Horizons System API can be found at:

One of the primary tools that will be used is the Horizons Batch File Conversion Tool found near the top of the main left-side menu. It will generate the core PHP source code which can be edited and customized. An entire program may then be developed around it as a starting point.
