DOP (Dilution of Precision) in Global Navigation Satellite Systems (GNSS) refers to a measure of the geometric quality of the satellite configuration as seen from a receiver. DOP is a dimensionless factor that describes the degree to which the positions of the satellites in the sky affect the accuracy of the calculated position. It gives an indication of the quality of the satellite geometry and the precision of the calculated position.

There are several types of DOP values, including: **There are several types of DOP values, including:**
- PDOP (Position Dilution of Precision): Indicates the dilution of precision in the calculated position of the receiver. A lower PDOP value indicates a better satellite geometry and a more precise calculated position. **- PDOP (Position Dilution of Precision):** Indicates the dilution of precision in the calculated position of the receiver. A lower PDOP value indicates a better satellite geometry and a more precise calculated position.
- HDOP (Horizontal Dilution of Precision): Indicates the dilution of precision in the calculated horizontal position of the receiver. A lower HDOP value indicates a better satellite geometry and a more precise calculated horizontal position. **- HDOP (Horizontal Dilution of Precision):** Indicates the dilution of precision in the calculated horizontal position of the receiver. A lower HDOP value indicates a better satellite geometry and a more precise calculated horizontal position.
- VDOP (Vertical Dilution of Precision): Indicates the dilution of precision in the calculated vertical position of the receiver. A lower VDOP value indicates a better satellite geometry and a more precise calculated vertical position. **- VDOP (Vertical Dilution of Precision):** Indicates the dilution of precision in the calculated vertical position of the receiver. A lower VDOP value indicates a better satellite geometry and a more precise calculated vertical position.
- GDOP (Geometric Dilution of Precision): Indicates the dilution of precision in the calculated three-dimensional position of the receiver. A lower GDOP value indicates a better satellite geometry and a more precise calculated three-dimensional position. **- GDOP (Geometric Dilution of Precision):** Indicates the dilution of precision in the calculated three-dimensional position of the receiver. A lower GDOP value indicates a better satellite geometry and a more precise calculated three-dimensional position.
The DOP values are calculated based on the positions of the satellites in the sky and the receiver's position. A high DOP value indicates that the satellites are not well-distributed in the sky and that the calculated position may be less accurate. A low DOP value indicates that the satellites are well-distributed in the sky and that the calculated position is likely to be more accurate.
