7.1 Algorithm
The algorithm the SOLYS is using to calculate the sun position is a free to use algorithm developed by J.J. Michalsky. (Working for
N.O.A.A.). One of the inputs for this algorithm is time! Six out of ten years the time needs to be corrected due to the earth slowing
down. This is what we call the ‘leap second’.
The SOLYS has a built in GPS receiver that constantly synchronizes the internal clock with the satellite clock (compensating for
drift in the RTC (real time clock) as for the equation of time, the correction is also applied into this algorithm.
