Abstract This paper presents the arrangement strategy of ground stations for a regional positioning system and derives the formulas for calculating GDOP with 4 grounds stations. With the flying users’ known altitude, the highest positioning precision can be acquired quickly. Since the formulas do not involve the multiplication and inverse of matrix, the calculations are reduced.
