User Manual

OPERA may be used very quickly via its GUI facilitating context elaboration and results exploitation. No code knowledge is necessary.

It is also possible to use it in batch mode via a shell and especially on grid computers with no display properties.

On the other hand, it is also possible to use it via its Java interface inside a higher level tool (for example, an orbit determination tool or a maneuver optimization tool).
