Update
•Click on the Update button to download Extended Ephemeris (EE) files from a secure
host on the Internet using any interface that has an Internet connection. These files
contain several days worth of ephemeris (orbital) data that can be used if the satellite’s
broadcast ephemeris is not available.
The Status field above the Update button displays the progress of the download, and once
successfully downloaded, the Status field will read Idle.
Settings
•Click on the Settings button to define the AGPS server connection settings.
The AGPS server connection settings drop-down menu allows you to choose from two set-
tings: Use default settings and Use custom settings.
The Use default settings option is generally acceptable for most applications. Note that aside
from the Update field in which you can choose how long the fix is stored in your Omnii, the
field values cannot be edited.
The Use custom settings option is generally used to configure devices that will have access
only to an intranet rather than the Internet and should only be altered with the assistance of
qualified Psion Teklogix personnel. They will be able to help you configure your Psion Tek-
logix devices and web server to retrieve the ephemeris data.
