filled when it is used for the fix solution. On the left side there are histograms indicating the S/N ratio
(SNR). The bar is filled when the satellite is used for solution. As a example, the satellite with PRN=11
is used for solution with SNR=34, Azimuth=170 degrees and Elevation=30 degrees.
HDG = Heading
The horizontal direction in which a ship actually points or heads in any moment (see also COG).
HDOP = Horizontal Dilution Of Precision
It is the index for position-fixing accuracy. The smaller the HDOP value, the more accurately the
position can be fixed (see Part B of "
