Download, parse and output orbital data from the NASA JPL HORIZONS system
The NASA JPL HORIZONS system is a powerful online utility that provides accurate orbital data for a lot of objects in the solar system (planets, moons, asteroids and spacecrafts).
Normally, with the GUI of the HORIZONS system, you have to search for each object individually, set the parameters, download the data and repeat this process.
However, this is too time consuming when you want data for hundreds of objects. This action can be automated using the telnet interface but you would need a program to generate the command list and store the responses anyway.
SolarSystemDataRetriever attempts to solve those problems by allowing you to:
· Batch download the raw orbital and physical data from the horizon system for a given list of objects.
· Parse and process the downloaded data, and output some relevant items in a well formatted CSV file.
Detailed instructions on how to install and use the SolarSystemDataRetriever utility on your Mac are available HERE.
SolarSystemDataRetriever is a cross-platform utility capable of running on any operating system that comes with Java support (e.g. Mac OS X, Windows, Linux).
