- The necessary observation space to achieve the lowest geometric dilution of precision (GDOP) based absolute-range measurement in two-dimension (2-D) wireless location systems is researched. Angle of coverage (AOC) is introduced as a parameter to describe the observation space. In fact, AOC reflects the geometric relationship between the target and the measuring points. A new clever geometric relationship between a target and N measuring points is proposed in this paper. And then, this geometric relationship is proved to have the minimum AOC to achieve the lowest GDOP in 2-D wireless location systems. It is shown that when the AOC is less than the minimum AOC, the lowest GDOP of could not be obtained. So the minimum AOC is called the necessary AOC. The necessary AOC is equal to when N is even, while the necessary AOC is monotonically decreasing to when N is odd. When the AOC is less than the necessary AOC, the optimal geometry is derived as well as its new low bound of GDOP.
