Precision
HDOP (Horizontal Dilution Of Precision) is a term used in satellite navigation to describe the error of positional precision as caused by the position of the satellites.
| HDOP value | Rating | Description |
|---|---|---|
| 0-1 | Ideal | Positional measurement at this value is the highest and most accurate possible. |
| 1-2 | Excellent | Positional measurements are considered accurate enough to meet all exept the most sensitive applications. |
| 2-5 | Good | Represents a level that marks the minimum appropriate for making accurate measurements. |
| 5-10 | Moderate | Positional measurements only provides a decent estimate of the current location. |
| 10-20 | Fair | Positional measurement only provides a very rough estimate of the current location |
| >20 | Poor | At this level, measurements are highly inaccurate. |
