Elev Mask : Displays the elevation mask currently set on
the General card of the Receiver Settings screen.
Note: If the receiver setup has not yet been performed,
the elevation mask will not be displayed. Also, if you
have changed the elevation mask setting, and have not
yet reconfigured this receiver, the value you see on this
display will be the value from the settings, and not the
value the receiver is currently using.
Sat Info
The Sat Info card displays signal quality information for
the satellites used by the receiver, and allows you to
disable tracking specific satellites, which is useful if the
receiver is tracking a ‘noisy’ satellite.
SNR Plot : This card lists all the satellites that are in
view and shows a bar graph that indicates the signal-to-
noise ratio. A longer bar indicates more noise, and a
lower-quality signal.
USI : is the universal identifier number of the satellite
that you wish to disable or re-enable. For GPS satellites,
this will be the Pseudo Random Noise (PRN) number
and will be between 1 and 37. For GLONASS satellites,
this will be the Frequency Channel Number (FCN) + 45,
and will be between 45 and 70.
Enable ALL : enable all the satellites that were disabled.
Disable SV : disables the USI entered above. This satellite will then
no longer be used in any solution until it is re-enabled.
Enable SV : re-enables the USI entered above.
SV List : This card lists signal quality information for each
satellite being used, which is reported by the receiver. The
columns available depend on the receiver being used.
