Sun tracker via GPS
 
Hello,
we try to design and build a sun tracker carrying a plate photvoltaîque, piloted by GPS,

GPS must locate the position of the sun and gives an order to move towards this position throughout the day,
but we really do not know where to start

all your suggestions and ideas will be welcome,

thank you in advance for your helps,
cordially

Sounds like a school project, so we need to hear your thoughts before we can offer any tutorial hints.

And if your PV panels are not mobile, you don't need an active GPS attached, right? Just a real-time clock, and an initial Lat/Long setting....

I don't understand what you are trying to achieve.

A GPS unit will tell you where it is on the surface of the Earth.

What does that have to do with the position of the sun in the sky? And how would a device" move towards this position"?

Hello,
we try to build an universal sun tracker, means that it work in any where (africa,USA, UE...), the system should localise it's position via GPS, and calculate the position of the sun...and orients th PV to the sun...
the problem is in the program that calculate the position in real time ??? and how can we transform these informations to control signal ?

thank you
