6.2 Status LEDs
6.2.1 R4 Navigation Sensor Status LEDs
The R4 Navigation Sensor has four LEDs that indicate its status. The red
LED marked “PWR” indicates when lit that power is applied to the Sensor.
The yellow “GPS” LED indicates when continuously lit that the Sensor has
obtained a solid GPS lock.
The yellow “CORR” LED indicates when continuously lit that the Sensor
has achieved a solid SBAS or radio beacon lock with marginal data error
rate. If the error rate is significant, this LED will blink showing that the lock
is marginal.
The green “DGPS” LED indicates when lit that the Sensor has attained and
is reporting a differentially corrected position. It may initially blink for a
short while until the pseudorange residuals of the navigation solution have
settled below a threshold value.
6.2.2 R4 Display Status LEDs
The three status LEDs of the R4 Display are used to indicate the current
RAIM state. The RAIM state can be one of
safe (green LED) , caution
(yellow LED) and unsafe (red LED). The different RAIM states are
described in the Operator’s Manual, section “RAIM Accuracy Limit” in the
Getting Started chapter.
6.3 System Power Up
The system is turned on by applying power to the R4 Navigation Sensor and
the R4 Display. The R4 Navigation Sensor does not have a switch for
turning it on, but instead starts directly once power is applied. The R4
Display is turned on by pressing the
POWER
key. The LEDs on the R4
Display should light up momentarily indicating that it is starting.
