There are several data monitoring views available depending on what measurements are
desired for monitoring and recording. Each view corresponds to one of the main categories in
the Device Settings window. For example, the 3DM - GX4 - 45
™
includes Sensor Data
Monitoring for the IMU measurements, GPS Monitoring for the GPS metrics, and
EF Monitoring for the Estimation Filter outputs (
Figure 12 - Data Monitoring and Streaming
).
During viewing and recording only the outputs that are selected in the Message Format tab of
the Device Settings menu are displayed and recorded (
see Sensor Settings on page 15
).
Data streaming must be started before data can be recorded, however it is not necessary to be
viewing it in a data monitoring window. Data monitoring is used primarily to confirm the system
is operating correctly or to view the outputs in near real time. If sensor setup has already been
confirmed, streaming and recording can be initiated from the main window.
Figure 12 - Data Monitoring and Streaming
is an example of Sensor Data Monitoring, which
displays the selected IMU measurements. In data monitoring windows, no data will be
displayed until data streaming is started, and no data will be recorded (even if it is being viewed)
until data recording is initiated (armed). In this example, the y-axis of the graph indicates data
points and the x-axis is the measurement units, and there is a tab for each measurement.
1. Right-click on the device in the main window and select Sensor Data Monitoring.
2. Press the Start Streaming icon to start sampling.
