The Thuraya IP terminal must be outside with a clear view of the sky. Line of sight to the satellite must not be blocked by things such as trees or buildings. Power up the terminal by pressing the Power button. The device will then attempt to acquire a GPS location. This may sometimes take a few minutes. For optimum GPS signal reception, make sure Thuraya IP is positioned in a horizontal position with the face up. Since GPS receivers must “see” a large part of the sky without obstructions from buildings, mountains or trees, it may be necessary to take your Thuraya IP out to a clear space to obtain a new GPS location. It may be possible to obtain a new GPS location in a less favorable circumstance, but the time to completion may be longer. The most recent GPS location is stored in Thuraya IP even when powered down. Upon power up, if this stored GPS location is available the display indicates “Using Stored Location.” Even so, Thuraya IP will attempt to update this GPS location since the Thuraya system will only allow access if your GPS location is not too old. If Thuraya IP is able to update the GPS location, the status changes from “Stored” to “Valid.” GPS location is shown as “Invalid” only under special circumstances when the stored information has been erased. In any case, you may wish to attempt network access to see if service will be granted.
