Communications

In this example we have an aircraft type Lockheed EP-3 Orient that is in charge of surveying a maritime area.

It is equipped with an optical rectangular sensor (10x5 degrees aperture) for threat detection. Any ship is detected as a threat. Then, the Aircraft tries to contact the command center to know with answer to apply against the threat.

Because the communication link between the Aircraft and the command center is not good enough, the Aircraft must wait until it gets a clear signal.

Then, when it gets a go, it fires a anti-ship Harpoon like missile.

STK is used for its analysis capabilities:

Build of a trajectory for the Aircraft with the Aircraft Mission Modeler tool (STK/AMM)
Build of a great arc trajectory for the Ship1
Setting of the optical and electronic components
Line of sight computations between the optical sensor and the ship
Computation of the signal quality between the aircraft emitter and the command center receiver

vsTASKER is used for the logic design, behaviors modeling and the missile capabilities:

Sensor models that remotely used the STK one for the detection events
Emitter/Receiver models that use STK counterpart for the signal quality report
Missile component
Logic to react to the threat detection (Aircraft to Command Center, Command Center to Aircraft, Aircraft to Missile, etc.)

Here, a threat is detected at: « 10 Nov 2011 11:02:20.885 »

The Aircraft communication signal is bad (less then 30 dB.Hz until « 10 Nov 2011 11:03:46.000 UTCG »)

The missile is controlled by vsTASKER and visualized into STK.
