Solar power received

Postby oliv » Tue Apr 08, 2014 11:19 am

Hello everyone,

I try to determinate the power received from the sun by a satellite.
I did every tutorials and try to find a way but I did'nt...!
That is why I posted this question here :)

Is there a way to define a solar panel area for the satellite ?

My aim is to determine the minimum area of panels to obtain a desired power (let say I want to know the area to obtain 10W of power, for one orbit at an given altitude).

If anyone could help me, I would really be grateful.
I wish you a very nice day.

Olivier.

Hi Olivier,

Unfortunately GMAT cannot not calculate power obtained from a solar panel.

GMAT is used for trajectory modeling only; for power calculations, you'll need another tool for that purpose.

Once you figure out a solar panel area, you can put that information into GMAT in the form of Spacecraft.DragArea and Spacecraft.SRPArea so that it can be used for drag and SRP modeling.

Thank you JJKParker for your quick answer and your advices.
I could read in the HELP that we cannot determine the eclipse and sunlight periods (for a satellite) yet, so I won't ask you :)

Have a nice day !

That's something we're actively working on. Expect news this fall.
