			== Introduction ==
			=== Scope ===
			Here are presented all the multi events detectors that could be used in multi propagation.

			Those event detectors are available in the packages :

			== Features Description ==
			=== Multi events detectors ===
			The following events detectors could be used in mono and multi spacecraft propagation :
			* [{{JavaDoc4.3}}//fr/cnes/sirius/patrius/propagation/events/ThreeBodiesAngleDetector.html ThreeBodiesAngleDetector]
			* [{{JavaDoc4.3}}//fr/cnes/sirius/patrius/propagation/events/ExtremaThreeBodiesAngleDetector.html ExtremaThreeBodiesAngleDetector]
			* [{{JavaDoc4.3}}//fr/cnes/sirius/patrius/events/sensor/SatToSatMutualVisibilityDetector.html SatToSatMutualVisibilityDetector]

			These three detectors extends [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/events/AbstractDetector.html AbstractDetector] and implements [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/events/multi/MultiEventDetector.html MultiEventDetector].

			Using [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/numerical/multi/MultiNumericalPropagator.html multi numerical propagator], all states concerned by the detection are recovered from the global state vector.<br>
			Using one of the [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/Propagator.html mono propagator] (analytical or numerical), the main state is recovered from the propagation. The others states concerned by the detection are recovered from a PVCoordinatesProvider.

			The meaning of the g switching function for the concerned event detectors, and their particularities are presented in dedicated chapter :
			* [MIS_ORB_Home Orbit determination events chapter]for [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/events/ThreeBodiesAngleDetector.html ThreeBodiesAngleDetector] and [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/propagation/events/ExtremaThreeBodiesAngleDetector.html ExtremaThreeBodiesAngleDetector]
			* [MIS_STASAT_Home Ground stations and satellites events] for [{{JavaDoc4.3}}/fr/cnes/sirius/patrius/events/sensor/SatToSatMutualVisibilityDetector.html SatToSatMutualVisibilityDetector]

			== Getting Started ==
			In multi numerical propagation case, the states concerned by the detection are identified with their ID. Specific constructors should be used in multi numerical propagation case.<br>
			These constructors take as parameter the ID of states concerned by the detection.

			Here after is presented the instanciation of a SatToSatMutualVisibilityDetectorin multi propagation case :

			<syntaxhighlight lang="java">
			// Initialize multi numerical propagator
			final FirstOrderIntegrator integratorMultiSat = new DormandPrince853Integrator(.1, 60, 1e-9, 1e-9);
			MultiNumericalPropagator mainPropagator = new MultiNumericalPropagator(integratorMultiSat);
			mainPropagator.addInitialState(mainState, STATE1);
			mainPropagator.addInitialState(secondaryState, STATE2);
			mainPropagator.setAttitudeProvider(attitudeProv, STATE1);
			mainPropagator.setAttitudeProvider(attitudeProv, STATE2);

			// Create SatToSatMultualVisibilityDetector
			final MultiEventDetector detector = new SatToSatMutualVisibilityDetector(STATE1, STATE2, mainSpacecraftSensorModel1, secondarySpacecraftSensorModel2, false, 0.01, 10.e-10);

			// Add detector
			mainPropagator.addEventDetector(detector1);

			// propagate
			Map<String, SpacecraftState> endStates = mainPropagator.propagate(date.shiftedBy(duration));
			</syntaxhighlight>

			If a wrong constructor is used, i.e a constructor for mono propagation, an exception will be raised during propagation.
