To solve for the North coordinates add A to the decimal of the minutes
To solve for the West coordinates subtract B from the decimal of the minutes
A=(H-0.13) x D/R
B=1.1 x H) x D/R
where H =the Frequency Band of operation (Freq) of transceivers =0.85Ghz
where D is the DR of cellular phone company
where R is the reverse DR of the cellular phone company
