GPS Diagnostic View
GPS Diagnostic View, which is only available when a GPS Receiver is
attached to you 900 Series, shows a sky chart and numerical data from the
GPS receiver. The sky chart shows the location of each visible GPS satellite
with its satellite number and a signal strength bar. A dark grey bar indicates
that the satellite is being used to determine your current position. A light gray
bar indicates that the satellite is being monitored, but is not yet being used.
This view also reports the current position, local time and date, and other
numeric information. The current GPS Fix Type is reported as No Fix, 2D Fix,
3D Fix, or Enhanced. An Enhanced fix has been augmented using
information from WAAS, EGNOS, or MSAS. A 3D or Enhanced Fix is required
for navigation. HDOP (the Horizontal Dilution of Precision) is a GPS system
parameter which depends on the current satellite configuration. HDOP is
used to calculate the Estimated Position Error.
