Basic Principle

OPERA proposed a Java interface. To use this Java interface, the developer will have to:

• Create the OPERA ReentrySimulation object with ...
  • a OperaConfigurationProperties object created from an existing file
  • a List<SolarActivityRow> object including actual and predicted solar activities
• call for a given method of the ReentrySimulation object with a list of TLE as arguments

To obtain the results, some "getters" method will be available depending on the type of computation.

How to initialize a Opera Properties

Thanks to the static method getConfigurationProperties from OperaConfigurationProperties class, we have just to precise the file path:

// Opera properties configuration
final OperaConfigurationProperties conf = OperaConfigurationProperties.getConfigurationProperties("data/opera-configuration.properties");
