Position-fixing accuracy (HDOP)

In radar position-fixing, most accurate posi- tion fixes are obtained when the targets used are spaced nearly 90° from each other. Simi- larly, GPS position fixing accuracy is subject to satellite location. Generally, the further apart the satellites are from one another, the greater the position-fixing accuracy.

For example, take a look at Figure 4-2. In both situations a fix is obtainable in the Northern Pacific region because three satellites are in line-of-sight. However, accuracy will be higher in the bottom figure since the satellites are spread farther apart than the satellites in the top figure.

The index for position-fixing accuracy is known as HDOP (Horizontal Dilution of Pre- cision). In simpler terms it is the geometrical relationship among 3 (or 4) satellites. The higher the HDOP value the less accurate the position fix. The error in distance is propor- tional to the HDOP value as shown in Figure 4-3.
