Solar Freaks

Hi guys am new to this site, am a final year student of Engg in instrumentation, am doing my final year project as a dual-axis solar tracker. my internal guide says that there is an algorithm which links the latitude,longitude and realtime clock to determine the sun's apparent motion, he also suggested i use a dsp processor for making the same, i really need ur help if there is such an algorithm, kindly help me out with it,also would appreciate ur inputs for the project
thanx

Try the SPA algorithm by Blanco-Muriel et al. http://www.psa.es/sdg/sunpos.htm
It requires latitude, longitude, UTC date and time which is readily available from GPS modules and is small enough to be used with a microcontroller. I have modified their code slightly to get it to work well with my Atmel-based microcontroller--but the code is hardware independent. You can look at it here: http://scottfromscott.blogspot.com/
