Calculation of azimuth

Calculation of azimuth
Calculation implant following C codes

Could somebody please help me implant following C codes into the program Flowcode 4.5 for Picmicro.
It is needed for calculation of azimuth and Alt for controlling of a solar tracker, which together with a GPS (Board EBC056-00-1) and C codes calculates Azimuth and Alt every 5 minutes.
I wish to implant the C codes azimuth east of north and Alt --- altitude above horizon.

See following web-site for C codes:

Above shows coordinates and other data which are the basis for the calculations.
Maybe as shown on YouTube insert C codes in ”Supplementary Code”.

Output:
az — azimuth east of north
alt — altitude above horizon

As I have no knowlegde of programming with C codes I need some help, please.

Hi Monie

The link you gave is for R code, here is a link with an in depth description and some code http://www.nrel.gov/docs/fy08osti/34302.pdf
One problem with using a Pic for this is that Sin,Cos etc is not a built in function and therefore you will need to calculate it, here are some of the methods discussed on this site.

Hi Gary
Many thanks for your answer.
Interesting Link.
Has no knowledge of C code, it will be very educational with an example in flow code for PICmicro.
Or is there anyone here on Matrix Multimedia Forums could make a ptogram examples.
