Horizontal Dilution of Precision
Satellite geometry silently dictates the precision of your GPS location every moment
7 days ago
0
How does satellite geometry influence Horizontal Dilution of Precision (HDOP) and GPS accuracy?
Wider satellite spacing lowers HDOP, improving horizontal positional accuracy.
Closer satellite clustering lowers HDOP, improving accuracy.
HDOP is unaffected by satellite positions and depends only on receiver quality.
