stkhelper 3.0.4

Uses the STK software to create simulations for satellite testing

STKHelper

STKHelper is a Python package designed for making interfacing with AGI's STK easier.

Installation

STKHelper is available on the Python Packaging Index and can be installed using pip

pip install stkhelper

Usage

Interfacing STK with Python can be difficult task due to its confusing class system, which involves lots of type casting and several references to the same object. To combat this, STKHelper implements a "guardian class relationship". Every object (with the exception of the application itself) has a guardian objects, which is the object that contains it. For example, a scenario is the guardian of all the satellites and area targets that are contained in the scenario. Similarly, a satellite is the guardian for all cameras that it contains.

from stkhelper import application, scenario, satellite, areatarget

app = application.Application()
scene = scenario.Scenario(app,'TestScenario','+24hr')
sat = satellite.Satellite(scene,'TestSat',25544)
at = areatarget.AreaTarget(scene, name="TestAT", coordList=[(5.0,-7.0)], radius=1.0)
cam = sensor.Sensor(sat, 'TestSensor', (15,35))

access = cam.GetAccess(at)

In this code snippet, an application is created. In that application, a scenario is added and the reference to the app is passed as the guardian in the declaration. When the satellite is created, the scenario reference is passed at declaration as the guardian. The reference to the guardian can always be returned with the following method on all objects:
