Your Nomad GPS receiver updates its position once every second.
It may take several minutes to start tracking the first time you try to
use it because it needs time to update its position and download
current satellite information from the GPS satellites. This process
will occur faster in a location with open sky.
After your Nomad has downloaded the current satellite information,
Assisted GPS (A-GPS) will retain a memory of the satellite paths
up to 72 hours. Therefore the Nomad can lock on the satellites
quickly, in less than 20 seconds in an open sky.
SatViewer provides a way to quickly start using the GPS
functionality of the Nomad, but it is not a stand-alone mapping, GIS
or navigation program by itself. SatViewer is useful for checking
the GPS configuration and enabling advanced features of your
Nomad GPS receiver when these settings are not made available in
other applications. When changing any GPS settings or other
settings, it is important to wait a few moments after tapping on the
desired option to allow time for your Nomad GPS receiver to
implement the requested change. SatViewer communicates with
your Nomad GPS receiver to compute your current position, speed,
direction (azimuth) and height. This information is displayed at the
top of the screen along with other information about the satellite
signals. Speed and direction measurements are only useful when
your Nomad GPS receiver is in motion. Standing in one position
with your Nomad GPS receiver may result in inaccurate readings in
direction and speed. If you are not moving, direction is reported as ?
and speed is reported as ―0‖. Height calculations from a GPS
receiver are typically not very accurate. Vertical accuracy is about
two to three times worse than the horizontal accuracy). Units of
measurement are only displayed in U.S. feet and heights are only
displayed in height above mean sea level (MSL).
The pages of the application are accessed by tapping the various
tabs, which are laid out in index card format. The information in
each tab is described on the following pages.
