On the right side of the screen (see Fig. 3.1.3), there is a polar representation of the
azimuth and elevation of each satellites. The circle contains a number indicating the PRN
of the satellite and it is 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 example, the satellite with PRN=10 is used for solution with S/N=44,
Azimuth=127degree and Elevation=70degree. When a valid fix is received, the Lat/Lon,
Date, Time, Altitude, VDOP, HDOP, SOG and COG are shown in the page.
