11) REC MONI menu

The REC MONI display, Figure 15 shows whether the system works normally or not. The
GPS receiver having the least tracking error rate reads 1.0. The error rate of other receivers is
between 0.7 and 0.9 normally. In the example of Figure 16, the receivers GPS2 and GPS3
have 20 % and 10% higher error rate than GPS1 respectively. If the error rate is 0.5 or less,
the receiver and/or the antenna may be defective.
The number of the satellite being used for heading calculation is displayed at the
right-hand side below CAL, and the number of the satellite being tracked below ALL.
The system requires 4 or more satellites for heading calculation.
The timer is reset by selecting "CNT Reset?".
