gpsDestLongitude property
Indicates the longitude of the destination point. The longitude is expressed as three unsigned rational values giving the degrees, minutes, and seconds, respectively. If longitude is expressed as degrees, minutes and seconds, a typical format would be ddd/1, mm/1, ss/1. When degrees and minutes are used and, for example, fractions of minutes are given up to two decimal places, the format would be ddd/1, mmmm/100, 0/1.
