Damping
This feature is used for achieving a more stable reading on the display if there are fluctuations
in the data received from the sensors.
The effect is accomplished by averaging the received data. A high value will cause delayed
update of the data on the display.
¼ Note: This is an internal damping on the display only. It will not change the data on the
network or on the NMEA 0183 output. It should be used when the sensor has no internal
damping function.
¼ Note: If damping for Heading is high when using the autopilot, the captured heading might
differ from the heading read on the display (heading capture function).
Conguring the GS25 GPS Antenna
The GS25 includes built-in sensors for both heading and position.
When a GS25 is connected to the system, this device will appear in the device list as both
GS25 Antenna and as GS25 Compass. Both the antenna and the compass devices should
be configured from the NSS.
GPS Antenna conguration
1. Tap the GS25 Antenna line in the device list to display the GS25 Antenna device information
dialog
2. Select the Configure button in the device information dialog to get access to the following
settings
Enable WAAS/MSAS/EGNOS
Activates the satellite based augmentation system (SBAS), which can further increase accuracy
of a GPS fix to within approximately 1 m. Coverage is not worldwide, as currently WAAS covers
North America, MSAS covers East Asia (primarily JAPAN), and EGNOS covers Europe. If you are
outside these regions, this function may be turned off in case the SBAS signal is still received
but actually worsens fix data.
