communications settings caused by another software application.
In most cases, the factory reset procedure only needs to be used
when another application has changed the settings of the Nomad
GPS receiver and you would like to set them back to their original
configuration.
NMEA / SiRF Binary: is where you choose to set your Nomad GPS
receiver to NMEA mode or SiRF Binary mode. When in SiRF Binary
mode, DOP values are not available in the Sky page. The mode you
select here will also determine the format for the information that can
be viewed from the Data View page. Most GPS applications require
that your Nomad GPS receiver be set to output NMEA messages.
There are some specialized GPS applications which require the SiRF
Binary output mode. Please consult the documentation of your GPS
application to see which output format you should use and then
choose that option via this setting.
Static Navigation: This feature keeps your Nomad GPS receiver from
showing the normal erratic positions when standing still. When
checked, small changes in your position are interpreted as GPS error
and your computed position will remain unchanged. For applications
where you will be mapping or navigating at walking speed or slower,
it is recommended to disable this feature, so even small changes in
position will be shown.
Smooth Tracking: This feature smoothes the track generated by your
Nomad GPS receiver. When checked, movement is smoothed
mathematically to reduce the seemingly jagged movement resulting
from GPS error. For unfiltered, raw GPS readings, you should leave
this box unchecked. However, if you want to see a smoother overall
position (e.g. while navigating), then turn this feature on via the
checkbox.
NOTE: Both the Static Navigation and Smooth Tracking features
modify your true GPS positions mathematically so these features
should not be used when you need the most accurate GPS positions
available.
