Sensor Ranges

GNSS Compass supports dynamic ranging on its sensors. Each of the three sensors have three different range settings. At lower ranges the sensor performance is better, but at higher ranges GNSS Compass can be used in more extreme dynamics. The best performance is achieved by choosing the lowest range that your application won't generate over-range events.

Sensor over-range events can be detected in the Filter Status field. In the web UI and GNSS Compass Manager the status indicator will go orange to indicate that a sensor has gone over-range. When a sensor goes over-range this causes the filter to become inaccurate, and in some cases it can cause the filter to reset.

By default GNSS Compass comes configured to the lowest (most sensitive) sensor ranges. In this configuration it is possible to send the gyroscopes over-range by quickly rotating the unit in your hand. It is recommended to monitor the web UI or GNSS Compass Manager when you do this.

The sensor range can be set using the Sensor Ranges page in the web UI or using the Using GNSS Compass Manager.
