Welcome to the OPERA wiki, a CNES flight dynamics tool.

DESCRIPTION

OPERA is a CNES tool allowing to estimate long and middle term Earth reentry dates (some months to one week in advance) thanks to TLE.

It allows also to compute the information on other parameters as S/M or maneuvers previously occured.

At last, OPERA is able to generate automatic PDF reports with a synthesis of maneuver activity of a given object.

Current version

The current version is: V7.2.

Previous versions

Quick start

First steps with OPERA

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).

HOW TO USE IT?

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).

So, three jar files are available:

opera-NN.n-jar-with-dependencies.jar : executable jar including all needed libraries => it is the file to use for GUI utilization but it may also be used for the Java interface
opera-NN.n.jar : includes only OPERA classes => to be used for Java interface, under the condition of linking with the right version of [GENOPUS] and [PATRIUS]
opera-NN.n-javadoc.jar

REMARKS

As it is coded in Java, this product is available for any kind of platforms owning Java. An executable jar (launching the GUI) including all dependencies is provided.
OPERA will be provided soon as a Freeware under a CNES specific license via this site.

CURRENT VERSION : V7.2-SNAPSHOT

New version, now linked with last PATRIUS V4.3 version.

Known bugs of this version: none.

PREVIOUS VERSIONS

version 7.1: Java 1.6 version.

-== WHAT IS OPERA? ==
-<font color=#556B2F>'''OPERA'''</font> is a [https://cnes.fr/fr '''CNES'''] tool allowing to estimate long and middle term Earth reentry dates (some months to one week in advance) thanks to <font color=#FF8C00 title="Two Lines Elements">TLE</font> and allows also to compute the information on other parameters as <font color=#FF8C00 title="Surface on Mass ratio">S/M</font> or maneuvers previously occured. <font color=#556B2F>'''OPERA'''</font> is also able to generate automatic <font color=#FF8C00 title="Portable Document Format">PDF</font> reports with a synthesis of maneuver activity of a given object.
-<font color=#556B2F>'''OPERA'''</font> is usable via three modes:
-* <font color=#FF8C00 title="Graphical User Interface">GUI</font>: its utilization is made user-friendly thanks to a graphical user interface (developed using [[http://genius.cnes.fr GENIUS]] and [[http://genopus.cnes.fr GENOPUS]]),
-* Batch,
-* Library via its <font color=#FF8C00>Java</font> interface.
-Its initialization is made by:
-* A list of initial orbital parameters thanks to <font color=#FF8C00 title="Two Lines Elements">TLE</font>,
-* Solar activity files,
-* Several other specific parameters as the reentry altitude or how to filter <font color=#FF8C00 title="Two Lines Elements">TLE</font> inputs.
-For flight dynamics aspects, <font color=#556B2F>'''OPERA'''</font> is fully based on the [[http://patrius.cnes.fr PATRIUS]] library and specially about the orbit extrapolation, the propagation is done thanks to the [[https://logiciels.cnes.fr/en/content/stela STELA]] propagator that allows to get interesting <font color=#FF8C00 title="Central Processing Unit">CPU</font> time by comparison to a full numerical propagator while keeping sufficient precision relative to the reentry date.
