2.1.4 Satellite status/location display
The satellite status/location display provides data about the GPS satellites and GEO
satellite (for WAAS). To display the satellite status/location display, do the following:
1. Press the MENU key to open the main menu.
2. Select [8. PLOTTER DISPLAY SETTING].
3. Select [1. SATELLITE STATUS/LOCATION] to display the satellite status/location
display.
DOP : DOP stands for Dilution of Precision and is an indication of the quality of the
satellite constellation. The smaller value means the higher accuracy. (For your ref-
erence, the positioning accuracy is approx. 10 m when the value is less than “4”.)
SS : SS (Signal Strength) displays a numeric representation of electrical field
strength of the received signal on the selected frequency. The higher the number
the stronger the received signal, and a figure above 60 is normal.
SN : SN (Signal-to-Noise) ratio displays the ratio between the desired signal and
unwanted noise on the selected frequency. The higher the SN ratio the better the
quality of the signal, and a figure above 21 is normal.
4. Press the DISP key to close the satellite status/location display and the menu.
