GPS Elevation Mask. Use the elevation mask to adjust the minimum elevation above the horizon which the
receiver may use in the position solution. This feature is adjusted in degrees above horizontal and may be used
to force the system to ignore satellites which are too low on the horizon. The default elevation mask is 5°.
Raising the elevation mask may cause the system to lose differential lock or could increase the occurrence of
HDOP issues. Unless instructed to raise the elevation mask by a technician, leave this value at the default value.
Differential/RTK Timeout. If the unit it RTK capable, this will be shows as RTK timeout. For other units it will be
Differential Timeout. Set the Differential/RTK Timeout value to the desired time to wait before the receiver will
switch to the next available differential correction source.
For example, if the receiver is configured to use an RTK correction source and RTK correction messages for this
source are not available for the set timeout setting, the receiver will automatically switch to the next available
correction source to continue field operations. The receiver will automatically resume RTK corrections when the
RTK correction source returns.
SETTING GPS MESSAGE OUTPUTS
NOTE: Raven receivers use NMEA 0183 protocols. NMEA 0183 is a combined electrical and data specification
for communication between marine electronics such as echo sounder, sonars, anemometer,
gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by,
and is controlled by, the National Marine Electronics Association.
To reconfigure NMEA output messages and message rates using the ROS device:
