WAAS/EGNOS
Note: The WAAS or EGNOS button is active only when the GeoSteer is powered up in an area where these signals are
available (North America and Europe).
WAAS (Wide Area Augmentation System) and EGNOS (European Geostationary Navigation Overlay Service) are two space
based correction services that provide deferentially corrected data to improve GPS positions. WAAS is available over North
America and EGNOS is available over Europe. These services are free to use by the public. There are multiple satellites in both
geographies that provide the correction signal.
To learn more about WAAS and its availability refer to: http://www.nstb.tc.faa.gov/RT_WaasSatelliteStatus.htm .
To learn more about EGNOS and its availability refer to: http://www.egnos-pro.esa.int/index.html .
If the system is powered up in a location where the system determines a WAAS or EGNOS signal should be available the user
will have to configure the primary and alternate PRNs for the respective correction source. The WAAS/EGNOS screen enables
you to select the Primary and Alternate PRN for your WAAS configuration. For the latest detailed WAAS/EGNOS
information and availability, please refer to the WAAS or EGNOS websites.
To access the WAAS or EGNOS screen, press the WAAS or EGNOS button from the GPS screen.
Note: The button, screens, etc. in this section will either show WAAS or EGNOS depending on the region the GeoSteer is
located. The GeoSteer requires a GPS position to determine if it should activate the button and which button to display.
