    Hi!
    I've scanned several GPS-Info sites, but with no luck.
    Can anyone tell me how to judge the HDOP. Which are consiedered to be
    good, average, bad? Is there an official rating and does anyone have a
    pointer for me?

    There is no official rating. Good HDOP may be considered below 2. Medium
    up to 4-5. Bad above 5. Very good below 1.

    Some devices/software may use certain HDOP thresholds, but they are not
    based on an official rating.

    You can use online sat prediction services or mission planning software
    to get a better practical idea on DOPs.

    Hi
    I've Scanned the several GPS device. Horizontal Dilution of Precision, 0.5‐99.9. Decimal
    digit.
    HDOP Values below 4 are great and value above 8 are
    bad
    HDOP is blank when no GPS fix.
