Special Radio Features
• In temperature extremes outside the operating limits of your RSM.
Even where location information can be calculated in such situations,
it may take longer to do so, and your location estimate may not be as
accurate. Therefore, in any emergency situation, always report your
location to your dispatcher.
Furthermore, please note that even where adequate signals from
multiple satellites are available, your GPS feature will only provide an
approximate location, often within 20-100 meters from your actual
location, but sometimes much further from the actual location.
Keep in mind that the accuracy of the location information and the
time it takes to obtain it varies depending upon circumstances,
particularly the ability to receive signals from an adequate number of
satellites.
The satellites used by the GPS feature are controlled by the U.S.
government and are subject to changes implemented in accordance
with the Department of Defense GPS user policy and the Federal
Radio Navigation Plan. These changes may affect the performance of
the GPS feature on your RSM.
Enhancing GPS Performance
Sometimes, the GPS feature of your RSM may be unable to complete
a location calculation successfully. You will then see a message
indicating that your RSM cannot see enough visible satellites.
To maximize the ability of your RSM to determine a fix, please note
the following guidelines:
• Stay in the open. The GPS feature works best where there is
nothing between your RSM and a large amount of open sky.
• Wear your RSM outside all clothing. Keep it as high on your body
as possible, ideally at shoulder level.
