The
When the receiver is in the process of acquiring enough satellite signals for
navigation, the receiver uses satellite orbital data (collected continuously from the
satellites) and last known position to determine the satellites that should be in view.
'Acquiring Satellites' is indicated as the solution until a sufficient number of satellites
have been acquired for computing a solution.
When the receiver is in the process of acquiring a 3D differential solution, '3D GPS
Location' is indicated as the solution until the 3D differential fix has finished acquisition.
SATELLITE INFORMATION
Satellites currently in view are shown at their respective positions on a satellite
constellation diagram. The outer circle of the constellation diagram represents the
horizon, the inner circle represents 45° above the horizon, and the center point shows
the position directly overhead. Each satellite is represented by a square containing the
Pseudo-Random Noise (PRN) number (i.e., satellite identification number).
