APPENDIX 4
SIGNAL QUALITY
Signal quality (SQ) is an indication of the carrier-to-noise ratio (C/N
o
) of
the signal of each satellite being used for a position fix. SO has no
affect on the accuracy of the position fix; it is only an indication of
signal strength.
SQ is displayed on the third screen of a position fix, backup fix, or
stored fix (waypoint), and ranges from 0 (lowest quality) to 9 (highest
quality). An SQ of 4 or higher indicates a signal strong enough that the
unit will not lose its lock on it.
