The SV Masking value can be changed from the default value 10 by entering an Elevation
Mask value between 7 and 20 degrees. This value must not be changed by other than
experts from the default value 10.

Click on the checkbox
Enable Range Rate Corrections
to use the DGPS corrections in
the GPS velocity calculations. The default setting is enabled on use of range rate
corrections. Disabling range rate corrections will reduce velocity and attitude noise when
receiving DGPS corrections from a reference station with a noisy range rate.

Click on the checkbox
Use Geo Range in position solution
to enable Seapath to use the
ranges from the Geo stationary satellites in the SBAS system like WAAS, EGNOS or
MSAS. Be aware that the Geos are less accurate than the GPS ranges. Geo ranges should
not be used without differential corrections, such as SBAS. The default setting is without
use of Geo ranges.

For the Seapath 200 RTK version the search mode for the RTK solution be changed from
the default mode "Normal" to "Safe" or "Fast" by pulling down the
RTK Search Mode
menu. The "Safe" mode is recommended used under difficult conditions with much
multipath or ionospheric activity and for long baselines. The "Fast" mode is used when a
fast RTK solution is required. However, in this mode the probability for an incorrect
solution from the system increases.
