Quick start

2021-03-09T16:48:07Z

Admin : /* Mandatory data */

'''OPERA''' proposes a lot of options and configurations. Anyway, in order to allow starting first computations very quickly, the '''OPERA''' GUI proposes many parameters set to default values.

=== Launch the main GUI ===

To launch the GUI you only have to double click on Windows systems or type :

java -jar opera-xx.x-jar-with-dependencies.jar

First time the GUI is launched, a specific directory ('''OPERA_DATA/''') with its sub-directories ('''context/''', '''outputrun/''', '''results/''', '''work/''' and '''AdditionalPatriusData/''') will be created if it does not already exist. These directories will be used to store data/results working files. Note that the name of these directories may be changed (see this specific [[OperaappConfigurationFile|page]] on properties files).

=== Mandatory data ===

If many data are already included in the jar file (solar activity, force models data, ...), no TLE data are directly provided. So the user will have to get it for example via the [[https://www.space-track.org/ Space-Track site]]. By default, these TLE will be stored: in the '''tles/''' subdirectory with the following organization: ''XXX/YY/XXXYY.tle'' file where ''XXX'' are the first three digits of the NoradId; ''YY'' are the last two digits of NoradId. The '''.tle''' contains history of TLE for this NoradId; see this example below ..

ERS 5 (Decayed 2011-11-11)
1 00579U 63014B 10315.35410215 .00050969 00000-0 82126-2 0 1077
2 00579 084.5011 267.0530 1931516 238.6291 101.2672 11.27537314522093
ERS 5 (Decayed 2011-11-11)
1 00579U 63014B 10315.88649764 .00051504 00000-0 82497-2 0 1086
2 00579 084.5012 266.8438 1931883 237.5999 102.3933 11.27595044522151
...
ERS 5 (Decayed 2011-11-11)
1 00579U 63014B 11314.41371939 .16010326 46685+0 20567+0 0 5309
2 00579 084.2585 103.8765 0162025 156.5631 204.1730 15.54826774565617

<big>'''So, in order to start easily, some files are available as examples (to put in the OPERA_DATA/tles directory) → [[:Fichier:OperaTles.zip|here]] ←'''</big>

=== Select Norad Ids ===

Based, for example, on the data given in the previous downloaded file, we can select which orbital objects to study. Different ways of selecting them are available (see this specific [[Configuration|page]] on the topic) but, as an example, we will use the simplest one, giving directly the Norad Ids by clicking on the '''Add''' button. We will enter the following integer numbers separated by blank characters:

[[Fichier:AddNoradIds.png]]

By clicking on '''OK''', the two objects are well selected and recognized (because files exists int the '''tles/''' directory!) as we can see it:

[[Fichier:QuickStartSelectedObjectsId.png]]

=== Computation ===

Now, it will be possible to start a computation by clicking on the [[File:ComputeButton.png]] button. Unfortunately, the computation exits in error status with such a message:

: ''TLEs was found in the requested time window. The last available date is xxxxx days too old''

This error is due to the fact that, by default, the "End of history" date is the current date and is too far from the actual reentry dates of these objects. So, in order to get results, we will have to change this date, entering this one: '''24/11/2011 00h00m00s'''

Clicking again on the [[File:ComputeButton.png]] button will then give these output results:

Main differences between V7.2.3 and V7.2.4

2021-03-09T15:23:55Z

Admin : /* Minor improvements */

This version mainly includes some minor corrections:

== Minor improvements ==

* A more explicit error message is displayed when a solar activity file is not available.
* Improvement of the GUI error management.
* Reentry date (and error on it) are now stored in xlsx/csv files even if no Orbit Determination is required.
* The choice of the maneuver detection method is now displayed with the GUI and both "Frequential" and "Kepler" methods are now available.
* Additional filtering in the maneuver "Frequential" algorithm to avoid errors when TLEs are built regularly at the same period (for example every day at the same hour).
* Use of the V1.10 version of the [http://genius.cnes.fr GENIUS] Library

== Anomaly corrections ==

* The '''SmSRPRefined''' (S/m obtained after orbit determination process) is now correctly displayed.
* Solar activity is now enabled at the GUI when a context file is loaded.
* Correction of the log4j initialization in the detection maneuver mode.
* Correction of an anomaly in the maneuver detection mode considering now the gap between two consecutive TLEs in seconds and no more in Julian days.

Since '''V7.2.2''', based on '''xlsx/cxv''' files as described [[Result_files|here]], when using the GUI, it is possible to plot some information.

First, the user will have to choose its file using the dedicated buttons (one for '''xlsx''' files, one for the '''csv''' ones). Once loaded, the content of the file will appear with a list of objects displayed in the same way as in the [[Configuration|Configuration panel]].

Anyway, it will be possible to use a filter in order to see only:
* Objects with a priori S/m information (as in the example below)
* Objects with refined S/m information
* Objects with orbit determination S/m information
* Objects with a reentry date information

[[File:Plotspanel.png|800px]]

Then, it will be possible to plot the S/m or reentry date evolution (in case of synthesis files) with one plot for each object:

[[File:PlotSmEvolution.png|400px]] [[File:PlotDateEvolution.png|400px]]

Moreover, only if the "Reentry date" filter has been activated, it will be possible to plot for all selected objects a "Gantt like" diagramm showing the reentry dates intervals.
A tooltip will appera on each interval togive some specific informaiton as in the following figure.

Admin :

The graphical interface is available by using its autonomous executable jar (no need other dynamic libraries). The main frame is then composed of four parts:

: [[Fichier:Bandeau.png]]

:'''1.''' The menu bar where the user may find the main commands via four menus: File, Windows, Option and About

:'''2.''' A banner where are stored some widgets corresponding to the main commands:
:: “'''Load context'''” button that will display a file explorer to select some previous '''OPERA''' context files (at XML format)
:: “'''Save context'''” button that will display a file explorer to select a name for the actual '''OPERA''' context
:: “'''Save results'''” button: in that case, a new window will appear where it will be possible to define the suffix with which the results files as well as the corresponding context file will be saved. Via this new window, it will also possible to (re)define the directories where to put these saved context and saved results files.

: [[Fichier:Save.png|900px]]

:: “'''Compute'''” button: to start … but also to stop the computation
:: “'''Clear results'''” button that will clear the output written in the specific Console tab (see [[Console|here]])
:: “'''Clear messages'''” button that will clear the sub window dedicated to messages
:: a progression bar that will indicate approximatively the progression of the propagation.
:: “'''Quit'''” button: to exit the application (also possible by clicking on the cross of the main frame)

:'''3.''' A sub window dedicated to messages as error messages.

:'''4.''' At last the main part of the frame dedicated to either input or output data. As there are many data, this frame has been split in different tabs that will be described on specific pages.

New version with some improvements vs V7.2.2 (see [[Main_differences_between_V7.2.2_and_V7.2.3|here]]).

Known bugs of this version:

* The displayed '''SmSRPRefined''' (S/m obtained after orbit determination process) is wrong. Next V7.2.4 will correct it. Anyway, the rest of the results are OK (as the re-entry date).

This version mainly includes some minor corrections and also some code improvements regards to quality aspects (so fully transparent to users).

* Correction of an anomaly when considering TLEs too near when checking for maneuvers existence
* The '''SLIDING_WINDOW_TIME''' property name was not correctly taken into account if users wanted to set it manually.
* Better initialization of [[https://logiciels.cnes.fr/en/content/patriusdataset PATRIUS_DATASET]] when asking for Pdf reports.
