The paper investigates the effect of system geometry of netted sensors on the performance of target position estimation. Each sensor can provide range and bearing measurements, bearing only and range only measurements. Analyses are based on the Cramer-Rao low bound and geometric dilution of precision in 2-dimensional plane. It is concluded that target position estimation accuracy is dependent not only on the range between the sensors and the target but also on the intersection angles between the sensors? line-of-sight to the target. Scenarios in which there are two or three sensors are discussed in detail.
