Elsewhere I was pointed to an on-line calculator that provides the regression/approximation functionality. One enters his data values, for example times of sights and their relevant HCs - then the approximating function is being searched for (automagically).
Having obtained such function the navigator can determine perfectly simultaneous HCs for the direct fix calculation SR.
Now I try to do this on a TI-83+ for off-line usage.
