Starflight I :- Latitude
In SFI latitudes are stored as words scaled by 480, with the equator being at 480.
So to extract a latitude from the data you need the following code.
if (word < 480) {
// SOUTH degrees
latitude = ((480 - word) * 90) / 480;
} else {
// NORTH degrees
latitude = ((word - 480) * 90) / 480;
}
