NAVIS NavDP 4000. Operation Manual
Figure 7.4: Gyro Usage Dialog
Light green
— normal operation. Data from the sensor are being used by
NAVIS NavDP 4000
;
Dark green
— data from the sensor are coming to
NAVIS NavDP 4000
, however, they are not used;
Red
— the sensor is not being used because of a fault. It can for instance be if the filter has been receiving incorrect data
for a long time, or there was no data at all, so that
NAVIS NavDP 4000
removed the sensor from operation.
To try the sensor to operation back press the sensor softkey;
Grey
— the sensor is not connected to
NAVIS NavDP 4000
.
7.2.5
Data Filter Indicator
The indicator can be of different colors:
Green
— the filter is working. Normal operation. Data from the sensor are coming and being processed by the filter;
Grey
— the filter is not working;
Red
— the data received by the filter are incorrect for a long time, or there was no data from the sensor for a long time,
or the filter has just started operation, and it takes a few seconds before the process has converged.
7.2.6
Data Indicator
The data indicator is represented as a black bar. When a piece of information comes to
NAVIS NavDP 4000
, it is
indicated as a narrow stroke. The stroke moves along the bar, from the left to the right. The distance between two adjacent
strokes corresponds to the time interval between two pieces of information. If the distance is very small, the strokes merge
into one line.
The color of a single stroke provides you with the information about the corresponding piece of data.
Green
— the data received from the sensor have a correct structure, they satisfy the accuracy criteria, and therefore, they
are used by the
NAVIS NavDP 4000
;
White
— sensor is in “Monitor” or “Not used” state, or the data received from the sensor have a correct structure,
however, they do not satisfy the accuracy criteria, and therefore, they are not used by
NAVIS NavDP 4000
;
Red
— the data received from the sensor have incorrect structure; therefore they are not used by
NAVIS NavDP 4000
.
7.2.7
Preffered Sensor Indicator
The
symbol indicates the main sensor. If there is only one sensor in a sensor group it is not indicated with this
symbol and becomes main.
7.2.8
Sensors Raw and Used Data Table
Sensor data are given in the table. In the first column you can see the following information:
1. Raw/used data. Press the table name for switching over. Used data is data with additive correction.
2. Deviations from the main sensor in comparison with raw/used data. The main (single) sensor has a zero deviation
that is not displayed.
If the raw data of any compass or VRS differ from the raw data of other sensors of the same type by about the same
value you should enter the correction. See Section “Gyro Sensor Details” (page 131) and Section “VRS Details” (page
133).
In the second column the
noise estimation
is shown.
Noise is estimated using Kalman-based filter, RMS value of noise for each sensor is shown.
