Fix Description
At the lower portion of the screen, just above the Tools menu, the GlobalPoint GPS
application displays the type of fix currently acquired by the GPS receiver. This value can
change over time as the receiver’s viewable sky changes, or if the receiver is re-initialized.
The types of fixes are:
Invalid unavailable solution – This signifies that not enough satellite data is available
to provide a fix. This occurs as the receiver is initialized or when an insufficient
number of satellites are in the viewable sky.
Corrected 3D point solution – This signifies that a three-dimensional GPS fix is
available and that it is corrected using WAAS or EGNOS. If available, WAAS
satellites are displayed in the satellite view as satellite numbers 35, 47. 48 and 51.
EGNOS satellites are displayed as 33. 37, 39 and 44.
Uncorrected 3D point solution - This signifies that a standard three-dimensional GPS
fix is available.
Uncorrected 2D point solution – This signifies that a two-dimensional GPS fix is
acquired.
